Flying insects are an important source of food supply all

through the winter, but with the increase of the number

of insects in March this activity greatly increases. The

observation post for fly-catching is usually the one in

which the nest hole is situated. But I noted at least one

bird that used four tall trees in succession for this

purpose. On February 1, 1927, a red-headed woodpecker was

seen clinging to the side of a telephone pole. Twice it

left the pole, flew out twenty feet, caught an insect each

time, and returned to the pole to eat it. Two weeks later

another bird was seen to make six trips similarly out

and back during six minutes, sometimes going more than a

hundred feet from its perch. As the bird went direct to the

insect, caught it and returned immediately to its perch,

it seemed likely that the insect was seen each time before

the bird started, indicating wonderful eyesight. While not

engaged in thus hawking, this bird hunted the limbs for

prey. Ten days later I found this bird watching for insects

and making ten fly-catching sallies in minute and a half.

Its flights were from ten to one hundred and fifty feet in

length, and all the insects were from forty to sixty feet

above the ground. One of the redheads seen fly-catching in

December, returned to its dead stub where it drilled for

grubs and borers in the usual woodpecker fashion, except

that its strokes were heavy and deliberate. On another

occasion, I saw one of these birds fly down into the road

to catch and eat an earthworm.

E. D. Nauman (1930), in Iowa, watched a red-headed woodpecker feeding

a young bird in the top of a tall tree. “The adult bird was at work,

darting off every few moments into the air in pursuit of insects and

returning after each flight to the young bird on the tree with its

prey. I watched and timed it carefully for an hour. It made from five

to seven trips per minute, always at an elevation of 50 to 100 feet,

and caught at each trip from one to three or more insects. * * *

“A computation based upon careful observation showed that a single

individual Redhead had destroyed over 600 insects in one hour. When I

left, the bird was still at work, and I am, of course, unable to state

how long it had been at work at this place before I came there.”

A. V. Goodpasture (1909), of Nashville, Tenn., made some interesting

observations on the feeding habits of this woodpecker. He watched one

preparing insect food for its young on a stump, some 4 feet high, near

its nest, and says:

When one of the woodpeckers came in, it did not go directly

to the nest, but always alighted first on this stump, where

it hammered away for a time, then proceeded to the nest

with a shapeless mass in its beak. My glass having failed

to disclose their object in thus lighting and hammering

on the stump before feeding their young, I went down to

reconnoiter. The place looked like a field hospital after a

severe engagement. There were wings, and wing-covers, heads

and legs strewn around the stump in great profusion. Then

I understood it all. The stump was their meat-block, and

they were preparing the food for their young by removing

the hard and indigestible parts. They dispatched this work

with much dexterity, without using their feet to confine

the insect; they laid it on the stump, and, with the bill

alone, succeeded in removing the undesirable parts.

The kinds of insects whose remains were found there was a

study. They were almost as gaudy as the woodpecker himself.

* * * Woodpeckers can undoubtedly distinguish between

colors; they find the ruddiest apple and the rosiest

peach in the orchard. In like manner, they seem to be

attracted by bright-colored insects. They prefer beautiful

butterflies, silky moths, and brilliant beetles. The

favorite food of this pair was the June-bug; not the plain

brown beetle of the northern states, but the beautiful

green and gold June-bug of the South--associated in the

mind with sultry summer days, and ripe blackberries, on

which he feeds. * * *

I found not only the dismembered wing-covers of the

June-bug around the Woodpecker’s meat-block, but, in a

pit on the splintered top of the stump, I found a live

June-bug. And what a prison he was in! It was a thousand

times worse than the Black Hole of Calcutta. They had

turned him on his back and pounded him into a cavity that

so exactly fitted him that he could move nothing but his

legs, which were plying like weaver’s shuttles in the empty

air. I always found the June-bugs deposited on their backs,

and always alive.

The red-headed woodpecker also shares with the California woodpecker

the provident habit of storing acorns and nuts. Fannie Hardy Eckstorm

(1901) says:

Lately it has been discovered that they not only eat

beechnuts all the fall, but store them up for winter use.

This time the observation was made in Indiana. There, when

the nuts were abundant, the red-heads were seen busily

carrying them off. Their accumulations were found in all

sorts of places; cavities in old tree-trunks contained nuts

by the handful; knot-holes, cracks, crevices, seams in the

barns were filled full of nuts. Nuts were tucked into the

cracks in fence-posts; they were driven into railroad ties;

they were pounded in between the shingles on the roofs; if

a board was sprung out, the space behind it was filled with

nuts, and bark or wood was often brought to cover over the

gathered store.

Unlike the California woodpecker, it does not make holes for the

reception of the nuts but uses what cavities it can find. Dr. Thomas

S. Roberts (1932) says that, on the outskirts of St. Paul, “a redhead

spent most of October putting acorns into cracks and climbing-iron

holes in a telephone pole and under the shingles of a near-by house.

One crack was closely plugged for a distance of twenty feet. When the

nuts were too large for the cracks they were split and driven in in

pieces.”

George A. Dorsey (1926) tells of an amusing attempt of a young redhead

to fill a hole in a telephone pole:

Finally he found a hole to his liking, and, chattering as

he worked, he drove the acorn in. Imagine my surprise when

I saw a couple of acorns fall out on the other side of the

pole! The hole was bored straight through the pole, and

the Woodpecker was wasting his time by pushing the acorns

through. He seemed to know that something was wrong, but

couldn’t quite reason it out. He would chatter agitatedly

and hitch around the pole to examine the other side of the

pole, but would finally give it up and go off for another

acorn. I watched him poke acorns in the hole several times,

only to have some of the ones he had previously placed

there fall out on the other side. On the ground under the

pole was about a double handful of acorns that had fallen

out.

E. D. Nauman (1932) saw a house mouse running across a paved street,

but it had not gone very far when a red-headed woodpecker “darted down

out of the grove and made an attack upon it. The woodpecker struck

the mouse several hard and vicious blows with its stout bill, rolling

and tossing it over and over. It appeared that a moment more of such

treatment must have finished the mouse, had not a vehicle approached

just at that instant, threatening to crush both the red-head and its

prey. The bird darted away just in time to save itself, and the mouse,

not having been struck by the wheels, hurriedly limped to the edge

of the pavement, got over the curb with difficulty, and hid in the

grass. The red-head flew back immediately to see what had become of its

prospect for dinner, but the mouse was so well hidden that the bird had

to give up the chase.”

Mr. DuBois writes to me that “a red-headed woodpecker was observed

hanging upside down from the small twigs at the end of a branch of a

large oak, evidently gleaning insect life of some sort from the twigs.

It flew to another tree and repeated this method of feeding.”

Lewis O. Shelley tells me that he observed one “feeding on ants in a

dry, harvested oat piece, obtaining the ants by thrusting the bill

into an ant tunnel entrance and working the bill to form a cone-shaped

opening, up through which the ants emerged at the disturbance, and were

licked up without the bill being withdrawn from this foodhopper.”

_Behavior._--Audubon (1842) writes attractively of the behavior of this

woodpecker:

With the exception of the mocking-bird, I know of no

species so gay and frolicksome. Indeed, their whole life

is one of pleasure. They find a superabundance of food

everywhere, as well as the best facilities for raising

their broods. * * * They do not seem to be much afraid of

man, although they have scarcely a more dangerous enemy.

When alighted on a fence-stake by the road, or in a field,

and one approaches them, they gradually move sidewise out

of sight, peeping now and then to discover your intention;

and when you are quite close and opposite, lie still until

you are past, when they hop to the top of the stake, and

rattle upon it with their bill, as if to congratulate

themselves on the success of their cunning. Should you

approach within arm’s length, which may frequently be done,

the woodpecker flies to the next stake or the second from

you, bends his head to peep, and rattles again, as if to

provoke you to a continuance of what seems to him excellent

sport. * * *

They chase each other on wing in a very amicable manner,

in long, beautifully curved sweeps, during which the

remarkable variety of their plumage becomes conspicuous,

and is highly pleasing to the eye. When passing from one

tree to another, their flight resembles the motion of a

great swing, and is performed by a single opening of the

wings, descending at first, and rising towards the spot

on which they are going to alight with ease, and in the

most graceful manner. They move upwards, sidewise, or

backwards, without apparent effort, but seldom with the

head downwards. * * *

On the ground, this species is by no means awkward, as it

hops there with ease, and secures beetles which it had

espied whilst on the fence or a tree.

Red-headed woodpeckers are quite quarrelsome at times with other

species; besides attacking various small birds, driving them away from

their nests, or robbing them of their eggs or young, they contend

with other hole-nesting birds, such as starlings and the smaller

woodpeckers, for the possession of nesting holes. They are jealous of

their food supply and will drive other birds away from their favorite

feeding places or from any choice morsel of food. They are generally

the winners in such encounters, even against such aggressive rivals as

blue jays and starlings. But toward birds of their own species they

are often solicitous, friendly, and helpful to birds in trouble. Mr.

DuBois writes to me: “A wounded female, after several attempts to fly,

fluttered to the ground; and while she was fluttering in the air, her

mate flew to her and apparently tried to help her to a place of safety.

After reaching the ground, the female lay still in the grass, although

only winged; but her mate clung to a nearby tree, from which he flew

down to her repeatedly, showing great distress.”

H. M. Holland (1931) tells the following story:

A red-head was caught by one wing, and possibly a foot,

in a crack formed at the tip of a tall, dead tree where

the trunk had been broken off and left a splintered stub.

Perhaps a dozen red-heads were present, all flying here

and there, evidently much excited, and make a great ado, a

veritable woodpecker hubbub.

First one and then another would alight just below and

apparently peck at, or more often while in flight would

strike or brush against the hapless victim, whose struggles

were renewed at each encounter. The clamor became actually

distressing. At times two or three were simultaneously

fluttering close to the captive. These activities continued

for several minutes when suddenly the bird was freed, to

accomplish which it would seem that a concerted effort

had been made. Quiet was restored almost at once and the

participants dispersed.

Julian K. Potter (1912) noticed that sparrows bothered his woodpeckers

considerably about their roosting holes and saw one of them fighting

two starlings for the possession of a cavity, but all were eventually

driven away and learned the lesson of “no trespass.” He says: “On one

occasion, when I watched the woodpeckers until dark, I found that one

went to roost in the nesting-hole about dusk, and the other, probably

the male, shortly after went into an old hole in the same dead tree

higher up.”

Mrs. John Franklin Kyler (1927) gives an interesting account of a

red-headed woodpecker that she raised by hand from the nest, beginning

before the young bird had opened its eyes; it developed into a very

satisfactory pet, with marked affection for its foster mother; anyone

who wants to try raising young birds could learn much by reading her

story.

_Voice._--Bendire (1895) writes: “Its ordinary call note is a loud

‘tchur-tchur’; when chasing each other a shrill note like ‘chärr-chärr’

is frequently uttered, and alarm is expressed by a harsh, rattling

note, as well as by one which, according to Mr. Otto Widmann, is

indistinguishable from the note of the Tree-frog (_Hyla arborea_). He

tells me that both bird and frog sometimes answer each other.”

Describing their spring notes, W. L. Dawson (1903) says:

Then the woods and groves soon resound with their loud

calls, _Quee-o--quee-o--queer_. These _queer_ cries are not

unpleasant, but the birds are a noisy lot at best. When one

of them flies into a tree where others are gathered, all

set up an outcry of _yarrow, yarrow, yarrow_, which does

not subside until the newcomer has had time to shake hands

all around at least twice. Besides these more familiar

sounds the red-heads boast an unfathomed repertory of

chirping, cackling, and raucous noises. The youngsters,

especially,--awkward, saucy fellows that most of them

are--sometimes get together and raise a fearful racket

until some of the older ones, out-stentored, interpose.

_Field marks._--The red-headed woodpecker is so conspicuously marked

that it hardly could be mistaken for anything else. The large white

areas in the wings and on the rump are much in evidence, in any

plumage, especially in flight. The bright red of the entire head and

neck and the plain white breast of the adult are also very conspicuous.

_Enemies._--The red-headed woodpecker has some bad habits, which have

at times caused considerable damage to property, arousing the enmity

of those who have suffered from its depredations and resulting in the

destruction of large numbers of these birds. Raids on cultivated fruits

have given these woodpeckers a bad name and many have been killed by

fruit growers. Audubon (1842) asserts that as many as “a hundred have

been shot upon a single cherry tree in one day. Pears, peaches, apples,

figs, mulberries, and even peas, are thus attacked.”

They do considerable damage to pole lines by excavating their nests in

them. An editorial in The Osprey (vol. 1, p. 147) quotes, as follows,

from an article in the Kansas City Star:

The little red-headed woodpecker has become such a nuisance

on the electric lines of the metropolitan street railway

system, that it has become necessary to appoint an official

woodpecker exterminator. The title has been conferred on

Coffee Rice, an Independence young man, and yesterday

he killed nineteen of the destructive birds on the

Independence line. The woodpeckers attack the large poles

which hold up the feed cables and dig holes into the center

and downward to a depth of more than a foot. * * * The

result is that in a season the water gets into the heart of

the pole and it rots off and breaks, requiring a new pole

to be set up; whereas, ordinarily, the life of the big pole

is several years. A large number of the electric line poles

have been ruined this way, and there was a threatened loss

of many thousand dollars unless the pest was checked.

Red-headed woodpeckers seem to be oftener killed on highways by

speeding automobiles than any other species, as attested by several

observers. Dr. Dayton Stoner (1932) made some observations on this

point on an automobile trip, on July 15, 1924, for a distance of 211

miles on well-graveled roads in Iowa. He says:

En route, 105 dead animals representing fifteen species

were counted; of these, thirty-nine were red-headed

woodpeckers. The mortality in this species was higher than

for any other species of vertebrate animal noted and I

believe that several contributory factors are responsible

for it. First, these birds have a propensity for feeding

upon insects and waste grain in and along the roads;

second, they delay taking wing before the approaching car,

in all probability being poor judges of its speed; and

third, they have a slow “get-away,” that is, they can not

quickly gain sufficient speed to escape the oncoming car.

However, I feel certain that a speed as high as thirty-five

to forty miles an hour is necessary in order to overtake

these birds.

Alexander Wilson (1832) writes:

Notwithstanding the care which this bird, in common with

the rest of its genus, takes to place its young beyond the

reach of enemies, within the hollows of trees, yet there

is one deadly foe, against whose depredations neither

the height of the tree nor the depth of the cavity, is

the least security. This is the black snake (_Coluber

constrictor_), who frequently glides up the trunk of the

tree, and, like a skulking savage, enters the woodpecker’s

peaceful apartment, devours the eggs or helpless young, in

spite of the cries and fluttering of the parents; and, if

the place be large enough, coils himself up in the spot

they occupied, where he will sometimes remain for several

days.

_Fall._--The fall migration is often well marked. A. H. Helme (1882),

writing from Millers Place, Long Island, N. Y., where the bird occurs

mainly as a migrant, says:

The first one observed this season was on the 10th of

September. On the 12th I saw three, and on the 20th I saw

one. Early on the morning of the 24th of September they

began to pass over in large numbers, and continued to pass

until about 10 o’clock, after which very few were seen,

except straggling groups of three or four, and occasionally

a single one was seen to pass over during the day. The

flight must have consisted of several hundred, principally

young birds. They came from the east and were flying west.

Many of them in their flight would alight for a few minutes

in the orchards and corn fields to feed on the half-ripened

corn, or search among the apple trees for the larva or eggs

of insects but would soon continue on their journey, and

their places would be supplied by others. I noticed one

or two to dart out and seize an insect in the manner of a

flycatcher. The following day but two or three were seen. A

few stragglers, however, were occasionally met with up to

the 10th of October, and one was seen as late as the 23rd

of November.

John B. Semple (1930) writes:

On September 16, 1929, a flight of red-headed woodpeckers

(_Melanerpes erythrocephalus_) was observed passing over

the marshes at the head of Sandusky Bay, Ohio. The birds

were flying in little groups of two to five against a

stiff southwest wind heading nearly south and at an

elevation of sixty to eighty yards. Rather more than half

of them were immature birds but the old and young were not

segregated. I was hunting ducks at the time and counted

forty-eight woodpeckers passing in a little more than two

hours. They apparently came from Ontario and probably

crossed Lake Erie by way of Point Pelee and Bass Island

which would make the flight over water only about nine

miles. It was interesting to note that each successive

group of birds followed exactly the same route over the

marshes although those that had gone before were well out

of sight.

_Winter._--The red-headed woodpecker is generally considered to be

a migratory species throughout the northern portion of its breeding

range, but its movements seem to depend almost entirely on the

abundance or scarcity of its winter food supply, mainly acorns and

beechnuts; when these nuts are available in considerable quantities,

this woodpecker is to be found in reasonable numbers within its summer

range in the northern States. When Dr. C. Hart Merriam (1878) referred

to it as remaining occasionally in northern New York, Lewis County, in

winter, some of his ornithological friends were skeptical. He says:

I therefore wrote to my friend, Mr. C. L. Bagg, asking

him to send me a lot of red-headed woodpeckers as soon as

possible, and in a week’s time received a box containing

over twenty specimens,--all killed in Lewis County and when

the snow was three feet deep! This was proof positive.

Notes kept by Mr. Bagg and myself during the past six

years show that they were abundant here during the winters

1871-72, 1873-74, 1875-76, and 1877-78; while they were

rare or did not occur at all during the winters of 1872-73

and 1876-77. Their absence was in no way governed by the

severity of the winters, but entirely dependent upon the

absence of the usual supply of beechnuts. While the greater

portion of nuts fall to the ground and are buried beneath

the snow far beyond the reach of the woodpeckers, yet

enough remain on the trees all winter to furnish abundant

subsistence for those species which feed on them. * * *

During the autumn the scattered pairs for several miles

around usually congregate in some suitable wood, containing

a plenty of beech-trees, and here spend the long cold

winter in company, chattering and chasing one another about

among the trees to keep warm, and to help while away the

time. “Coe’s woods,” in this immediate vicinity, has long

been famous as the great winter resort for the red-headed

woodpeckers of the neighborhood, and it is certainly the

most suitable place for their purposes to be found for many

miles around. This piece of woods, not over an eighth of

a mile in extent, contains, besides hundreds of beeches

(_Fagus ferruginea_), a large number of elms (_Ulmus

americana_), and white ash-trees (_Fraxinus americana_) of

great size, most of the tops of which are now dead. What

more favorable location than this woods could a woodpecker

desire? Here they have beechnuts in abundance and a

bountiful supply of dead limbs and tree-tops far above the

reach of the small charges commonly used by bird-collectors.

James B. Purdy (1900) says that “the presence of the Red-headed

Woodpecker (_Melanerpes erythrocephalus_) during the winter months in

Michigan does not depend upon the temperature, but entirely upon the

food supply, viz.: the crop of acorns and beechnuts which precedes the

winter. If these nuts are plenty, the red-headed woodpeckers will

always be found during the winter months, but in no great abundance. If

there are no acorns or beechnuts, this bird will be entirely absent in

our Michigan forests.”

Robert Ridgway (1881) writes:

Ordinarily this species (_Melanerpes erythrocephalus_)

is decidedly the most numerous of the Woodpeckers in

Southeastern Illinois, while during the winter season it is

often so excessively common in the sheltered bottom-lands

as to outnumber all other species together, and, in fact,

is voted a decided nuisance by the hunter, sportsman,

or collector, on account of its well known habit of

following any one carrying a gun, and annoying him by its

continued chatter; at intervals sweeping before him and

thus diverting attention. Being at this season always

semi-gregarious, while they are of all woodpeckers the most

restless and sportive, the annoyance which they thus cause

is really no trifling matter.

Evidently, they do not always spend the winter even here, for he says:

“In the early part of October, 1879, I paid my usual yearly visit to my

old home, and scarcely had arrived at the house ere my father informed

me, as a bit of news which he was well aware would both interest and

surprise me, that the red-headed woodpeckers had all migrated; that for

a number of nights preceding he had heard overhead their well-known

notes as they winged their way to some more or less distant region; in

short, that the woods that had been their home ‘knew them now no more.’”

Even as far south as South Carolina, according to Arthur T. Wayne

(1910): “The controlling influence upon the migration of this species

in winter is the presence or absence of acorns of the live and water

oaks. If the crop of acorns is large, this woodpecker is abundant

during the winter months, but if there are no acorns, the bird is

entirely absent, no matter whether the season is mild or severe.”

DISTRIBUTION

_Range._--Southern Canada and the United States east of the Rocky

Mountains; irregularly migratory in the northern parts of its range.
