XI. A FELLOW OF EXPEDIENTS.

[Illustration]

Among the birds there is one whose personal appearance is rapidly

changing. He illustrates in his present life a process well known

historically to all naturalists, viz., the modification of form

resulting from changed environment. I refer to the golden-winged

woodpecker, perhaps the most beautifully marked bird of the North,

whose names are as varied as his habits and accomplishments.

Nature intended him to get his living, as do the other woodpeckers, by

boring into old trees and stumps for the insects that live on the

decaying wood. For this purpose she gave him the straight, sharp,

wedge-shaped bill, just calculated for cutting out chips; the very

long horn-tipped tongue for thrusting into the holes he makes; the

peculiar arrangement of toes, two forward and two back; and the stiff,

spiny tail-feathers for supporting himself against the side of a tree

as he works. But getting his living so means hard work, and he has

discovered for himself a much easier way. One now frequently

surprises him on the ground in old pastures and orchards, floundering

about rather awkwardly (for his little feet were never intended for

walking) after the crickets and grasshoppers that abound there. Still

he finds the work of catching them much easier than boring into dry

old trees, and the insects themselves much larger and more

satisfactory.

A single glance will show how much this new way of living has changed

him from the other woodpeckers. The bill is no longer straight, but

has a decided curve, like the thrushes; and instead of the

chisel-shaped edge there is a rounded point. The red tuft on the head,

which marks all the woodpecker family, would be too conspicuous on the

ground. In its place we find a red crescent well down on the neck, and

partially hidden by the short gray feathers about it. The point of the

tongue is less horny, and from the stiff points of the tail-feathers

lamina are beginning to grow, making them more like other birds'. A

future generation will undoubtedly wonder where this peculiar kind of

thrush got his unusual tongue and tail, just as we wonder at the

deformed little feet and strange ways of a cuckoo.

The habits of this bird are a curious compound of his old life in the

woods and his new preference for the open fields and farms. Sometimes

the nest is in the very heart of the woods, where the bird glides in

and out, silent as a crow in nesting time. His feeding place meanwhile

may be an old pasture half a mile away, where he calls loudly, and

frolics about as if he had never a care or a fear in the world. But

the nest is now more frequently in a wild orchard, where the bird

finds an old knot-hole and digs down through the soft wood, making a

deep nest with very little trouble. When the knot-hole is not well

situated, he finds a large decayed limb and drills through the outer

hard shell, then digs down a foot or more through the soft wood, and

makes a nest. In this nest the rain never troubles him, for he very

providently drills the entrance on the under side of the limb.

Like many other birds, he has discovered that the farmer is his

friend. Occasionally, therefore, he neglects to build a deep nest,

simply hollowing out an old knot-hole, and depending on the presence

of man for protection from hawks and owls. At such times the bird very

soon learns to recognize those who belong in the orchard, and loses

the extreme shyness that characterizes him at all other times.

Once a farmer, knowing my interest in birds, invited me to come and

see a golden-winged woodpecker, which in her confidence had built so

shallow a nest that she could be seen sitting on the eggs like a

robin. She was so tame, he said, that in going to his work he

sometimes passed under the tree without disturbing her. The moment we

crossed the wall within sight of the nest, the bird slipped away out

of the orchard. Wishing to test her, we withdrew and waited till she

returned. Then the farmer passed within a few feet without disturbing

her in the least. Ten minutes later I followed him, and the bird flew

away again as I crossed the wall.

The notes of the golden-wing--much more varied and musical than those

of other woodpeckers--are probably the results of his new free life,

and the modified tongue and bill. In the woods one seldom hears from

him anything but the rattling _rat-a-tat-tat_, as he hammers away on a

dry old pine stub. As a rule he seems to do this more for the noise it

makes, and the exercise of his abilities, than because he expects to

find insects inside; except in winter time, when he goes back to his

old ways. But out in the fields he has a variety of notes. Sometimes

it is a loud _kee-uk_, like the scream of a blue jay divided into two

syllables, with the accent on the last. Again it is a loud cheery

whistling call, of very short notes run close together, with accent on

every other one. Again he teeters up and down on the end of an old

fence rail with a rollicking _eekoo, eekoo, eekoo_, that sounds more

like a laugh than anything else among the birds. In most of his

musical efforts the golden-wing, instead of clinging to the side of a

tree, sits across the limb, like other birds.

A curious habit which the bird has adopted with advancing civilization

is that of providing himself with a sheltered sleeping place from the

storms and cold of winter. Late in the fall he finds a deserted

building, and after a great deal of shy inspection, to satisfy himself

that no one is within, drills a hole through the side. He has then a

comfortable place to sleep, and an abundance of decaying wood in which

to hunt insects on stormy days. An ice-house is a favorite location

for him, the warm sawdust furnishing a good burrowing place for a nest

or sleeping room. When a building is used as a nesting place, the bird

very cunningly drills the entrance close up under the eaves, where it

is sheltered from storms, and at the same time out of sight of all

prying eyes.

During the winter several birds often occupy one building together. I

know of one old deserted barn where last year five of the birds lived

very peaceably; though what they were doing there in the daytime I

could never quite make out. At almost any hour of the day, if one

approached very cautiously and thumped the side of the barn, some of

the birds would dash out in great alarm, never stopping to look behind

them. At first there were but three entrances; but after I had

surprised them a few times, two more were added; whether to get out

more quickly when all were inside, or simply for the sake of drilling

the holes, I do not know. Sometimes a pair of birds will have five or

six holes drilled, generally on the same side of the building.

Two things about my family in the old barn aroused my curiosity--what

they were doing there by day, and how they got out so quickly when

alarmed. The only way it seemed possible for them to dash out on the

instant, as they did, was to fly straight through. But the holes were

too small, and no bird but a bank-swallow would have attempted such a

thing.

One day I drove the birds out, then crawled in under a sill on the

opposite side, and hid in a corner of the loft without disturbing

anything inside. It was a long wait in the stuffy old place before one

of the birds came back. I heard him light first on the roof; then his

little head appeared at one of the holes as he sat just below, against

the side of the barn, looking and listening before coming in. Quite

satisfied after a minute or two that nobody was inside, he scrambled

in and flew down to a corner in which was a lot of old hay and

rubbish. Here he began a great rustle and stirring about, like a

squirrel in autumn leaves, probably after insects, though it was too

dark to see just what he was doing. It sounded part of the time as if

he were scratching aside the hay, much as a hen would have done. If

so, his two little front toes must have made sad work of it, with the

two hind ones always getting doubled up in the way. When I thumped

suddenly against the side of the barn, he hurled himself like a shot

at one of the holes, alighting just below it, and stuck there in a way

that reminded me of the chewed-paper balls that boys used to throw

against the blackboard in school. I could hear plainly the thump of

his little feet as he struck. With the same movement, and without

pausing an instant, he dived through headlong, aided by a spring from

his tail, much as a jumping jack goes over the head of his stick, only

much more rapidly. Hardly had he gone before another appeared, to go

through the same program.

Though much shyer than other birds of the farm, he often ventures up

close to the house and doorway in the early morning, before any one is

stirring. One spring morning I was awakened by a strange little

pattering sound, and, opening my eyes, was astonished to see one of

these birds on the sash of the open window within five feet of my

hand. Half closing my eyes, I kept very still and watched. Just in

front of him, on the bureau, was a stuffed golden-wing, with wings and

tail spread to show to best advantage the beautiful plumage. He had

seen it in flying by, and now stood hopping back and forth along

the window sash, uncertain whether to come in or not. Sometimes he

spread his wings as if on the point of flying in; then he would turn

his head to look curiously at me and at the strange surroundings, and,

afraid to venture in, endeavor to attract the attention of the stuffed

bird, whose head was turned away. In the looking-glass he saw his own

movements repeated. Twice he began his love call very softly, but cut

it short, as if frightened. The echo of the small room made it seem so

different from the same call in the open fields that I think he

doubted even his own voice.

[Illustration]

Almost over his head, on a bracket against the wall, was another bird,

a great hawk, pitched forward on his perch, with wings wide spread and

fierce eyes glaring downward, in the intense attitude a hawk takes as

he strikes his prey from some lofty watch tree. The golden-wing by

this time was ready to venture in. He had leaned forward with wings

spread, looking down at me to be quite sure I was harmless, when,

turning his head for a final look round, he caught sight of the hawk

just ready to pounce down on him. With a startled _kee-uk_ he fairly

tumbled back off the window sash, and I caught one glimpse of him as

he dashed round the corner in full flight.

What were his impressions, I wonder, as he sat on a limb of the old

apple tree and thought it all over? Do birds have romances? How much

greater wonders had he seen than those of any romance! And do they

have any means of communicating them, as they sing their love songs?

What a wonderful story he could tell, a real story, of a magic palace

full of strange wonders; of a glittering bit of air that made him see

himself; of a giant, all in white, with only his head visible; of an

enchanted beauty, stretching her wings in mute supplication for some

brave knight to touch her and break the spell, while on high a fierce

dragon-hawk kept watch, ready to eat up any one who should dare enter!

And of course none of the birds would believe him. He would have to

spend the rest of his life explaining; and the others would only

whistle, and call him _Iagoo_, the lying woodpecker. On the whole, it

would be better for a bird with such a very unusual experience to keep

still about it.
