Purple Finch
Carpodacus purpureus [Eastern
Purple Finch]
[Published

Bulletin 237 (Part 1): 264-278]
The above name may be misleading to the novice, for it is no
more purple, as we understand the term today, than it is blue or
yellow. Crimson finch would be a more appropriate name. (However,
the "purple" of the Bible and of classical writers was
not very different from the red of the male purple finch.) The
species has also been called "linnet" and even
"purple grosbeak."
Before the introduction and the subsequent increase of the
house sparrow, during the last quarter of the previous century,
the purple finch was a common summer resident in southern New
England, where we now know it almost entirely as a winter visitor.
J. A. Allen (1869) wrote at that time: "Nearly all observers
in Southern New England that I have met remark that this bird has
greatly increased there during the last ten years; especially it
is more numerous in the breeding season." It was certainly
common enough when I was a boy in the 1870s. We could find plenty
of nests in the spruces near our homes and we caught the birds
under sieves, or in cage traps; they made attractive pets as cage
birds, for they sang well in captivity.
But, as the sparrows increased, the finches became steadily
rarer until now, when only an occasional pair can be found nesting
in southeastern Massachusetts. William Brewster (1906) tells a
similar story for the Cambridge region: "Up to within
twenty-five or thirty years the brilliant, ecstatic song of the
Purple Finch might be heard through May, June and early July in
almost every part of Cambridge--including even Cambridgeport. Many
were the nests of this bird that I used to find in our Norway
spruces and other ornamental evergreens, but since the English
Sparrows became numerous the Purple Finches have abandoned one
favorite urban haunt after another, and, excepting at their
seasons of migration, I seldom see or hear them now in the older
settled parts of Cambridge."
This is certainly true of the increasingly densely built up
urban areas, but, reports C. H. Blake, some sizable populations
still breed in the outer ring of suburbs. In Lexington, Mass.,
backyard trapping by Mr. and Mrs. Parker C. Reed has shown a fair
number of breeding birds present. In some (approximately
alternate) years many birds in juvenal plumage come to the traps
in late summer and fall. They banded 343 such in 1954. Of course
these represent the production of a considerable area;
nevertheless singing summer males are not really uncommon 15 to 18
miles from Boston. At the present time the controlling factor is
more likely to be the availability of suitable nesting trees
rather than the house sparrow.
Spring.--Wells W. Cooke (1914)
makes the following interesting observation.
The great bulk of the individuals winter south of the
breeding range, but a small percentage remain at this season,
farther north in the southern part of the breeding range, and
sometimes even to the middle part. There is therefore a broad
belt, covering at least a third of the entire range of the
species, in which migration dates are unsatisfactory, because the
records of real spring migration are so mixed with notes on birds
that have wintered. The case is made more involved by the fact
that the Purple Finch is normally a late migrant, so that there
are, in reality, two sets of notes, one of birds that have
wintered unnoticed in the deep woods and are recorded when they
spread to the open country during the first warm days of spring,
and the other of migrants from the south that arrive two to six
weeks later.
As Cooke implies, the spring migration is later than one might
suppose. In Pennsylvania (Groskin, 1950) it is in March and April;
in eastern Massachusetts, in April and May. While there is
certainly a generally northward movement, it is questionable as to
what extent migrating finches set even a roughly true north
course. The data presented by Groskin (1950) show a northwestward
course toward Michigan and a northeastward one into New England
from his station in southeast Pennsylvania; northward recaptures
of his banded birds were few and the distances mostly less than
100 miles. He was also able to show that an occasional bird makes
a fairly long southward trip in spring.
Courtship.--Much has been
written about the ecstatic and colorful courtship display of the
purple finch. One of the best accounts of it is in the following
note sent to me by Kenneth C. Parkes, who observed the performance
at Ithaca, N.Y., at 5:30 a.m., daylight saving time, on May 19,
1940: "When I first approached the pair, the male bird was
hopping around with dangling wings and thrown-up chest, much in
the fashion of the male house sparrow. The female was feeding on
the grass nearby, not paying the least bit of attention to the
male. His wings beat faster and faster until quite blurred. His
tail was cocked up in the air like that of a wren. All this time
he was chippering softly. Finally, with wings beating seemingly
fully as fast as those of a hummingbird, he rose a foot or so
straight up in the air.
"The female flew over at this point, and the male came
down directly on top of her, although she immediately slipped out
from under him. The male leaned over backward at an almost
impossible angle, with his wings dangling against the ground and
his bill pointed straight up in the air. The female gave a little
jump and hit the male's bill with hers. Both birds immediately
flew into the branches of a small birch, under which the
performance had taken place. Although I was no more than 15 or 20
feet from the birds during the performance, and was right out in
the open, they took absolutely no notice of me."
Gordon B. Wellman (1920) gives a similar account of the
display, but adds some interesting features. When the male
"was about two inches from and in front of" the female
he picked up a straw, dropped it and picked up a piece of
grass which hung from each side of his bill. This seemed to be the
signal for the greatest agitation on his part; with ecstatic
dance, full song and vibrating wings he moved slowly on beating
feet, back and forth before the female; then he rose six inches in
the air, poured forth glorious song notes and dropped to the
ground at one side of the female. He landed on his feet but
instantly took a most dramatic pose by holding stiffly his spread
tail to the ground and tilting back on that support with head held
high, the raised crest and carmine ruff adding to the effect. Then
like a little tragedian he rolled over on his side, apparently
lifeless; the song ceased and the straw fell from his bill. Up to
this time the female had remained oblivious as far as outward
manifestation showed, but now she turned quickly and gave the male
as he lay "dead" a vicious peck in the breast, whereat
he came to and flew up in the tree, a normal bird once more, and
was soon singing in the usual deliberate fashion from a high
perch. The female busied herself about the spot where he had just
danced and soon finding the straw and grass which he had dropped
she picked them up in her bill and flew into the tree where she
went searching from place to place for a spot to start a nest.
Sometimes the courtship consists largely of competition in
song. Rev. J. H. Langille (1884) quotes an observation made by
Eugene Ringueberg, who saw a female alight on a branch, after
having been chased by two males, singing as hard as they could;
the males alighted near her, and each "faced the female with
neck outstretched and crest raised to its fullest dimensions, and
leaned forward far enough to show conspicuously its bright rump,
and to aid in this display, spread both wings and tail to the
widest extent; and moving, or more properly dancing, up and down,
poured forth such a volume of song as I did not think them capable
of producing."
Mrs. Louise de Kiriline Lawrence, writing from Rutherglen,
Ontario, says she watched a male dance before a female. The male
had a piece of nesting material, a pine needle in his bill. His
crest was raised like a plume; his wings drooped and vibrated like
a hummingbird's; his tail was raised. He uttered a continuous,
soft warbling song with the most exquisite whistles and passages.
The display continued for at least a minute and a half. The female
paid no attention. The next day, June 3, a generally similar
performance took place. This time the female flew up onto a rock,
"tucked" softly, sank herself down, lifted her tail, and
began trembling her wings. The male, in an ecstasy, flew toward
her. He had nothing in his bill. She sank down deeper, rippled her
wings faster. The male lifted himself from the rock on wings
fluttering so rapidly as to be practically invisible and descended
upon her for about two seconds, a fairy union on the rock in the
sun. When the act was ended, both birds sat motionless, facing
each other for several seconds. Then the female shook herself and
flew off. A moment later the male followed.
Nesting.--Nearly all the nests of
the purple finch that I have seen or read about have been placed
in coniferous trees, mainly spruces. In my egg-collecting days, we
boys could always find one or more nests in a row of white
spruces, built along a suburban road as a windbreak. The nests
were fairly well concealed in the thickest parts of the trees and
not far from the tops, perhaps 15 or 20 feet from the ground. But
I once found one in an apple tree in an orchard. The nests were
made of fine twigs and rootlets and were lined with finer rootlets
and horsehair.
In the Cambridge region of Massachusetts, William Brewster
(1906) found purple finches nesting "in hilly pastures
sprinkled with Virginia junipers among the dense foliage of which
they love to conceal their nests." They bred there so
commonly at one time that he "found no less than six nests
containing eggs or young within a space of half an acre," on
June 6, 1869.
E. A. Samuels (1883) says: "The nest is usually built in a
pine or cedar tree, and is sometimes thirty or even forty feet
from the ground--oftener about fifteen or twenty. It is
constructed of fine roots and grasses, and is lined with horsehair
and hog's bristles. One specimen in my collection has the cast-off
skin of a snake woven in the rest of the fabric; and I have seen
nests lined with mosses."
Eggs.--The eggs laid by the purple
finch vary from three to six, with four or five most commonly
found. They are slightly glossy and ovate, sometimes tending to
short-ovate. The ground color may be "pale Niagara
green," or "Etain blue," and they are sparingly
speckled and spotted with shades of "olive-brown,"
"deep olive," "citrine drab," "mummy
brown," and black. The usual type has sharp and clearly
defined spots of black and browns scattered over the entire egg.
Less frequently the eggs are marked with clouded spots of the
lighter tones such as "citrine drab" and "deep
olive," but all show a tendency to concentration of spots
toward the large end where they often form a loose wreath.
The measurements of 50 eggs average 20.2 by 14.6 millimeters;
the eggs showing the four extremes measure 22.4 by 14.2,
19.8 by 16.8, 17.8 by 13.7, and 20.1 by 13.5
millimeters.
Young.--Ora W. Knight (1908) writes:
"Both male and female assist in building the nest, but I have
only once caught the male assisting in the task of incubation, and
then he was perched on the eggs half standing and literally
bursting with melody. . . . The male frequently feeds the female
while she is incubating, and when not so engaged is perched on the
top of some nearby tree singing his best.
"Incubation requires about
thirteen days and the young leave in fourteen more. Both parents
Feed them for a considerable while after they have left the
nest."
Francis H. Allen wrote in his notes for June 25, 1911: "A
young one in a shad bush, fed by its father, makes a constant
sweet little pee-wee note. The old bird gathers the
June-berries industriously for a long time, doubtless swallowing
many, but apparently retaining some in the mouth or gullet, for
the feeding process is a prolonged one. The young when being fed
is very eager and vociferous and follows its parent up when the
latter starts away. The old bird chews the berries, sometimes if
not always, and sometimes picks off only part of one at a time,
perhaps when the fruit is not ripe enough to be easily detached.
The pee-wee note seems to be characteristic. I hear it from
others of the young. The syllables are about evenly
accented."
Plumages.--Dwight (1900)
describes the juvenal plumage of the eastern purple finch as
follows: "Above, wood-brown, broadly streaked with
olive-brown and showing whitish streaks if the feathers be so
disarranged as to expose a lighter portion. Below, dull white
streaked with paler olive-brown, least on the chin, throat and
middle of abdomen and crissum, the last two areas often unmarked.
An indistinct whitish superciliary line. Wings and tail deep
olive-brown, edged with pale buff deepest and broadest on
tertiaries and wing coverts. . . ."
Minor exceptions may be taken to Dwight's description,
according to C. H. Blake (1955). The throat is completely streaked
but the streaks are very narrow. In fact, all the streaking of the
under parts in the juvenal plumage is narrower than in first
winter plumage. Finally, among birds handled in eastern
Massachusetts, streaks occur on the juvenal under tail coverts in
nearly 90 percent of the individuals.
The first winter plumage is acquired by a partial postjuvenal
molt involving the contour plumage and the wing coverts, but not
the rest of the wings or the tail. This is not very different from
the juvenal plumage, but "the streaks are bolder, the brown
usually with a greenish yellow tinge merging into the buffy
edgings" (Dwight, 1900).
In eastern Massachusetts, according to Blake, the inception of
postjuvenal molt is quite evenly distributed over the period from
August 4 to September 8. The duration of this molt is probably
about 8 weeks. In the Lexington, Mass., sample of 343 juvenile
birds 26 percent (roughly half the males) showed some ruddy or
pinkish tints in the first winter plumage. The available evidence
from returns of banded birds is that all such birds are males.
This ruddy coloring varies in intensity from a very faint tinting
to color approaching that of the adult male. Its area may be very
restricted or may extend to practically all the regions that are
red or rosy in the fully colored male.
The first nuptial plumage is acquired by wear, most of the
buffy tints being lost and the edgings becoming whitish. The birds
breed in this plumage and the males sing.
The adult winter plumage is acquired by a complete postnuptial
molt, beginning in July or early August, at which old and young
birds become indistinguishable, the males assuming the pink
plumage. Dwight (1900) describes the male as follows: "Above,
pale geranium-red (often carmine or brick-red), hoary on the
pileum and nape, the feathers of the back with dusky shaft lines
and broad greenish buff edgings. Below, a hoary geranium-pink
blending into white on abdomen and crissum, the flanks buffy with
a few dusky streaks. Wings and tail clove-brown the edgings tinged
with pale brick-red."
The adult nuptial plumage is acquired by wear, the hoary effect
disappearing and the reds and pinks becoming clearer and brighter.
C. H. Blake reports that the molts of the female are the same
as those of the male and that for 2 years or more she resembles
closely the brown first winter plumage. Thereafter, in at least
some populations, the female acquires a coloration very like that
of the reddened first winter males described above. On the average
such old females are a little less extensively reddened than the
young males. A very few females develop a general yellowing the
the plumage.
Dwight (1900) remarks: "In captivity pink adults assume
golden or bronzed feathers at their first moult, never reassuming
the pink dress."
Several articles have been published by bird banders who have
noticed abnormal coloring in portions of the plumages of purple
finches. Notable among these is the veteran bird-bander, M. J.
Magee, of Sault Ste. Marie, Mich., who had banded and examined no
less than 6,157 purple finches up to 1927, and as many as 1,168 in
a single year. ***
Charles L. Whittle (1928) and Helen G. Whittle (1928) have
noted such abnormal coloring in banded purple finches. The former
writes: "Buffiness and bright yellow olive are common on the
upper parts of many birds of this race, the latter usually
appearing of greatest intensity on the rump of old females, and
the former usually regularly placed on the sides of or including
the breast of both young and old birds, especially noticeable on
old birds in fresh postnuptial plumage, when they can hardly be
distinguished from juvenile birds. Such buffy color is also not
infrequently irregularly placed on the breast, one example being a
well-marked band nearly one-half inch wide crossing it
diagonally."
Helen G. Whittle (1928) refers to these as color-phases,
"erythrism and xanthochroism." A female, "banded
June 15, 1924, was a return-3 in 1927, at which time it was an
olivaceous bird having a 'dull rosy rump with a central patch of
rich olive-yellow.' As a return-4, May 9, 1928, the crown had a
few crimson feathers, and the rump and upper tail-coverts were
yellow with patches of rich reddish brown in the latter
area."
Magee (1924) lists a number of females and young males showing
some yellow or red in the plumage.
Some patches of yellowish or olive color, particularly on adult
males, are evidently a result of feather replacement at a time
when the bird's diet cannot provide the red pigment (C. H. Blake).
Food.--Ora W. Knight (1908) sums up
the food of this finch very well as follows: "As to the food
of the Purple Finch, the species is primarily a seed eater during
the winter and spring, eating all sorts of weed and grass seeds,
also to a lesser extent a few buds of apple, maple and birch as
well as other tree buds. In late spring they eat some insects,
such as beetles, green caterpillars and small larvae of various
sorts. In summer they are fruit eaters to quite an extent,
partaking of strawberries, raspberries, blackberries, cherries,
both wild and cultivated and many other fruits. They seem to
relish the fruit of the dogwoods, elders and viburnums very
much."
Alexander F. Skutch writes to me: "In Maryland on October
27, 1929, I watched a purple finch feeding on the dry 'cones' of
the tulip poplar. One by one it pulled the winged scales from the
cluster, and with one deft bite cut out the seed from the thicker
end of each, then allowed the empty wing to flutter slowly to the
ground."
Hervey Brackbill observed that, near Baltimore, Md., its food
included berries of the Japanese honeysuckle, seeds of tulip tree,
white ash, American elm, and Chinese elm, and buds of oaks and red
maple.
Charles H. Blake of Lincoln, Mass., says that it "eats
buds of Populus tremuloides, Prunus serotina, and Ulmus
americana in early spring. In winter, feeds on fruits of Juniperus
virginiana and Ilex verticillata."
Mrs. Amelia R. Laskey, of Nashville, Tenn., has seen purple
finches feeding on the berries of a privet hedge and perched on a
twig, nibbling at hackberries.
Purple finches are very fond of the seed balls of the sycamore
and the sweet gum in the south, and farther north they feed on
sumac berries and the buds of the balsam fir, in addition to the
items mentioned above. Their well-known habit of feeding on the
buds and blossoms of fruit trees is discussed under their economic
status, below.
Economic Status.--When we see the
purple finches flocking into our orchards in the spring and a
shower of blossoms falling to the ground, we are apt to condemn
them as detrimental to the interests of the orchardist. But here
is what Edward H. Forbush (1913) has to say in its defense:
This Finch appears at first sight to be destructive, for it
devours buds and the blossoms of apple, cherry, peach, and plum
trees, feeding on the stamens and pistils. . . . They feed also
upon the blossoms of the red maple, the seeds of such trees as the
white ash, and the berries of the red cedar, mountain ash, and
other trees. But, as with the Grosbeak, the pruning or cutting of
buds, blossoms, and seeds of trees is not ordinarily excessive. On
the other hand, this bird eats many of the seeds of the most
destructive weeds, ragweed being a favorite. The Purple Finch also
destroys many orchard and woodland caterpillars. It is
particularly destructive to plant lice and cankerworms. Its quest
of weed seeds is sometimes rewarded by some insects which it finds
on the ground, among them ground beetles and perhaps a few
cutworms.
In further exoneration of the purple finch as a bud and blossom
eater, M. J. Magee (1926a) published two photographs of one of his
apple trees, one showing the tree in full blossom and the other
showing it so heavily laden with apples that the branches had to
be supported. Eleven bushels of apples were taken from that tree,
better apples than ever and "hardly a wormy one in the lot. I
doubt if their budding does any harm, certainly not to apples in
any event." More purple finches were in his trees that year
than ever before.
Another exonerator, Horace Groskin (1938), who raises seckel
pears in Pennsylvania, writes: "I have found, during the past
three years, that the pruning the birds give the tree is decidedly
beneficial. In the fall of each year when the birds were present
in the spring, I have noted a very marked improvement in the
amount of fruit on the tree, and last year we not only had the
largest number of pears on this tree we ever had before, but a
great many of the pears were double the size of the normal seckel
pear, and the flavor seemed to be decidedly improved. Let us be
fair to the Purple Finch."
Behavior.--Purple finches are
more or less gregarious at times, especially in winter; they are
sociable and friendly at such times, except when feeding causes
rivalry. Then they become selfish and belligerent. When several of
them are eating at a feeding station they often seem quite hostile
toward any new arrival, raising the feathers of the crown and
rushing at him with wide-open bill. Occasional pecking may result,
which seems to produce no great damage. The attacked one usually
retreats somewhat and proceeds to feed only a few inches from his
pursuer.
Hervey Brackbill says in his notes: "On one occasion a
migrant in the female or immature plumage flew against the window
at which my feeding tray is placed, in what appeared to be
shadow-boxing. There were three such finches on the tray, the
floor of which is above the window frame and runs within 6 inches
of the pane. After all the birds had eaten for a while, the one
nearest the window apparently noticed its reflection there. It
stopped feeding and began moving back and forth along the very
inside edge of the tray, with now one eye and now the other cocked
toward the pane; sometimes it stood still for appreciable periods
and stared. Once it rubbed one side of its head and then after a
bit the other, against the edge of the shelf; the impression it
gave was that of rubbing its eyes, as if to see whether the bird
in the glass would then still be there. Then it resumed its
movement back and forth along the edge of the tray, always looking
at the window. Finally, perhaps 1 to 2 minutes after it had first
caught sight of its reflection, it flew up and struck the window
pane once and then flew away. The other birds went on
eating."
Sun-bathing, common with robins and some other birds, is
sometimes indulged in by purple finches. Mrs. Herman F. Straw
(1919) describes it as follows:
One day I noticed one of the birds squatting on the shelf,
tail and one wing spread out to the fullest extent, one leg
stretched as far as possible to one side, its neck turned so far
around that the head seemed upside down, mouth open, and feathers
fluffed out all over the body. Such a strange position! I felt
sure this Finch was dying, and feared I had given it something
that had poisoned it. . . . Consequently I was much relieved when
another Finch, flying to the shelf just at this time, pecked the
first bird, instantly restoring him to life and flight. Since then
I have often seen seven or eight birds at the same time, in as
many ungainly and ludicrous positions, "sunning"
themselves in the bright, hot sunshine.
Voice.--Aretas A. Saunders
contributes the following thorough study of the beautiful song of
this finch: "The song of the purple finch is loud, clear,
highly musical, and pleasing. There are three distinct ways of
singing, more or less separated by the seasons of the year. The
warbling song of early spring is probably the best known of these.
This song is used while the birds are in flocks, and there are
often several birds in the flock singing at once, in a chorus. The
territory or nesting song comes a little later, after the birds
are separated into pairs. The least common song is the 'vireo
song,' which comes very early in the spring, or rarely in late
fall or other seasons.
"The warbling song, according to 21 records in my
collection, consists of from 6 to 23 notes. The notes are very
rapid, and connected, with no two in succession on the same pitch.
Liquid consonant sounds are common between the notes and
connecting them. There is great variation in the song. Each song
by one individual is likely to be followed, after a short pause,
by another that is quite different in its notes and the
arrangement of them. If a bird ever repeats one of these warbling
songs again, exactly as it was, I have been unable to detect it.
The pitch varies, in my records, from C''' to C''''. Songs vary in
length from 1 to 3 1/5 seconds, and average about seven notes to a
second. It is heard chiefly from February to April, but I have
some records, from the Adirondacks, dated in July, after the
nesting was over.
"The territory song is heard commonly from late April till
July, wherever there are breeding birds. It is quite different
from the warble. A few groups of notes in it are warbled, but
there is a series of rapid notes, all on the same pitch, near the
beginning of the song, and a high-pitched, strongly accented note,
usually near the end. The song does not vary in the individual, as
does the warble, but is the same in all details when repeated.
When it is sung the birds are not in flocks so that, ordinarily,
only a single individual is heard at one time. The bird often
sings the song over and over, several times in succession, without
a pause, a habit that is also common to the entirely unrelated
ruby-crowned kinglet. I have 18 records of this song. The pitch
varies from E''' to D'''', and the length from 2 3/5 to 3 1/5
seconds. But when the song is repeated over and over, it is, of
course, much longer than this. I once watched a bird singing this
repeated song in flight, holding its wings up at an angle and
floating in the air, somewhat after the manner of the flight song
of a longspur.
"The 'vireo song' is the least common of the three, and is
usually to be heard in early March, or in late October or
November. This song is made up of phrases of two to five notes
each, and these phrases are alternated, with short pauses between
them, in much the same manner as red-eyed and yellow-throated
vireos. The song is less variable than any of the vireos, however,
generally consisting of three different phrases only. While
usually a spring or fall song, I once heard it in July in the
Adirondacks, and then the bird singing it was in the plumage of a
female, though probably an immature male.
"I have one record, from such an immature male, of a song
of primitive character--a mixture of warbles, trills, and series
of rapidly repeated notes, lasting about 5 seconds and varying in
pitch from A''' to D''''.
"The chief season of singing in this species lasts from
late February or early March to July. There is occasional singing
in October or early November.
"The call note of this bird is a short, sharp tip
or tick. A young bird, out of the nest calling for food,
used a two-note phrase that sounded like yo wee, the second
note two and one-half tones higher than the first."
Francis H. Allen writes to me: "I have records of several
unusual purple finch songs. Perhaps the strangest of them was
heard in West Roxbury, Mass., May 9, 1939. It seemed to be a
medley of goldfinch song-notes with a recurrent imitation of the
towhee's call, usually followed by a high-pitched trill suggesting
the trill of the towhee's song but very rapid and beady in
quality, and with a long, high-pitched, even note that suggested
the cowbird."
Field marks.--The adult male
purple finch is easily recognized by its color; no other
sparrowlike bird of that size is similarly colored in rosy
crimson. The female is marked more like a sparrow, but its
markings are more like stripes, its bill is much heavier, and its
tail is sharply emarginate. The immature male resembles the
female. [EDITOR'S NOTE: See House Finch Field
marks.]
Enemies.--Man is, or rather was,
one of the worst enemies of this fine bird; in my boyhood days, it
was easy to trap all the purple finches in the neighborhood in
cagetraps baited with a singing male; in those days, there was
considerable traffic in trapped cagebirds, and these
"linnets" made most attractive ones; but, happily, this
traffic has now been stopped, in this country at least.
Evidently, the purple finch is not very often imposed upon by
the cowbird. Friedmann (1929) says: "This species is
occasionally imposed upon by the Cowbird, there being several
cases on record. . . .
"As many as four eggs of the Cowbird have been found in a
single nest of this bird together with seven of the owner."
Considerable has been published on the longevity of purple
finches, based on the records of birdbanders. While the lifespan
of the species apparently does not average more than 3 or 4 years,
many individuals have managed to escape their enemies for 6 or 7
years, and a few have lived to be 8 or even 10 years old.
Fall.--The fall migrations of purple
finches are somewhat erratic and irregular, varying in direction
and extent. M. J. Magee (1924) writes from Michigan: "In the
fall there is a tendency for the sexes to flock separately.
Several times late in the fall flocks of from twenty to thirty,
all crimson males, have dropped in for from a few hours to a day
or two and then moved on. The following is from my 1922 notes:
'Have not had a crimson male at house from Aug. 23 to Oct. 4,' and
my banding records show that after Aug. 7 I banded no crimson
males although I trapped and banded 111 birds."
The migration route is usually from north to south, but
Frederick C. Lincoln (1939) says that "banding studies have
demonstrated that in addition to the normal north-and-south
journeys there is also an east-and-west movement, since birds
banded in Michigan have been subsequently recaptured at banding
stations in New England."
Winter.--Most of us in New England
have recently come to regard the purple finch as mainly a winter
visitor since it has ceased to be a common summer resident here.
We cannot always count on seeing it, as its visits are somewhat
uncertain, being abundant some winters and scarce or entirely
absent in others. When it does come, we welcome the little bands
of rosy-colored males and striped females that flock to our
feeding shelves, quarreling among themselves for the sunflower
seeds and other food.
On rare occasions they have come in such large numbers as to be
referred to as invasions. Such a visitation is described by
Richard Lee Weaver (1940) as follows:
In the winter and spring of 1939, January to May, an unusual
invasion of Purple Finches (Carpodacus purpureus) occurred
throughout the northeastern United States and the Maritime
Provinces. . . . Hundreds, and in many places thousands, of the
birds congregated and fed on weed seeds and buds, or on grain
supplied at many feeding stations. Sunflower seed was preferred to
most other foods, and thousands of pounds of it were consumed. In
one small town, over one thousand pounds of the seed were sold in
one week during the invasion.
In the seven years prior to 1939, an average of 4,700 Purple
Finches were banded throughout the country. In 1939 there were
21,592 birds banded. . . . Each of six or seven banders was
responsible for banding over one thousand of the birds. Several
people banded almost two thousand.
During their stay with us in New England, they are sometimes
seen roving over the open country with flocks of siskins or
goldfinches, feeding on weed seeds, wild fruits, buds, catkins,
and such seeds as remain on the trees. But, where they are
encouraged to do so, they congregate about our houses and
grounds, where they can find food. They are hardy birds and can
live through severe winter weather if well fed.
Forbush (1929) says: "They bathe in brooks with the
temperature below freezing point and some have been known to sing
in the clearing weather directly after a blizzard. Nevertheless a
few are overcome by starvation and cold, as occasionally one has
been picked up from the snow helpless or dead. . . . Purple
Finches spend winter nights in dense evergreen trees or thickets,
or even in some open buildings or under the shelter of a cupola
roof."
They wander as far south in winter as Louisiana and northern
Florida. Arthur T. Wayne (1910) says that, in South Carolina, they
"inhabit only forests which are of a deciduous growth and
feed upon the seed of the sweet gum (Liquidamber styraciflua),
and sycamore (Platanus occidentalis) during November,
December, and a portion of January. The birds evidently migrate to
points to the southward of South Carolina during midwinter for few
are to be seen until the ash (sp?) and red maple (Acer rubrum)
begin to flower about the middle of February, when there is a
distinct migration."
