Family PICIDÆ.—The Woodpeckers

Char. Outer toe turned backwards permanently, not versatile laterally, the basal portion of the tongue capable of great protrusion.

The preceding characters combined appear to express the essential characters of the Picidæ. In addition, it may be stated that the tongue itself is quite small, flat, and short, acute and horny, usually armed along the edges with recurved hooks. The horns of the hyoid apparatus are generally very long, and curve round the back of the skull, frequently to the base of the bill, playing in a sheath, when the tongue is thrown forward out of the mouth to transfix an insect.

There are twelve tail-feathers, of which the outer is, however, very small and rudimentary (lying concealed between the outer and adjacent feathers), so that only ten are usually counted. The tail is nearly even, or cuneate, never forked, the shafts very rigid in the true Woodpeckers; soft in Picumninæ and Yunginæ. The outer primary is generally very short, or spurious, but not wanting. The bill is chisel or wedge shaped, with sharp angles and ridges and straight culmen; sometimes the culmen is a little curved, in which case it is smoother, and without the ridges. The tarsi in the North American forms are covered with large plates anteriorly, posteriorly with small ones, usually more or less polygonal. The claws are compressed, much curved, very strong and acute.

The Picidæ are found all over the world with the exception of Madagascar, Australia, the Moluccas, and Polynesia. America is well provided with them, more than half of the described species belonging to the New World.

The subfamilies of the Picidæ may be most easily distinguished as follows, although other characters could readily be given:—

Picinæ. Tail-feathers pointed, and lanceolate at end; the shafts very rigid, thickened and elastic.

Picumninæ. Tail soft and short, about half the length of wing; the feathers without stiffened shafts, rather narrow, linear, and rounded at end.

Yunginæ. Tail soft and rather long, about three fourths the length of wing; the feathers broad, and obtusely rounded at end.

Of these subfamilies the Picinæ alone occur north of Mexico. The Yunginæ, to which the well-known Wryneck of England (Jynx torquilla) belongs, are exclusively Old World; the Picumninæ belong principally to the tropical regions of America, although a few species occur in Africa and India. One species, Picumnus micromegas, Sundevall, belongs to St. Domingo, although erroneously assigned to Brazil. This is the giant of the group, being about the size of the White-bellied Nuthatch (Sitta carolinensis) the other species being mostly very diminutive, varying from three to four inches in length.

Subfamily PICINÆ

The diagnosis on the preceding page will serve to distinguish this group from its allies, without the necessity of going into greater detail. It includes by far the largest percentage of the Picidæ, and in the great variations of form has been variously subdivided by authors into sections. Professor Sundevall, in his able monograph,¹²⁴ establishes the following four series, referring all to the single genus Picus:—

I. Angusticolles. Neck slender, elongated. Nostrils concealed by bristles. Tail-feathers black or brownish, immaculate.

II. Securirostres. Neck not slender, and shorter. Nostrils concealed by bristles. Bill stout, cuneate, with the nasal ridges widely distant from each other.

III. Ligonirostres. Neck not slender. Nostrils covered, nasal ridges of bill placed near the culmen (or at least nearer it than the lower edge of the upper mandible), for the most part obsolete anteriorly.

IV. Nudinares. Nostrils open, uncovered by bristly hairs. Neck and bill various.

Of these series, the first and second correspond with Piceæ, as given below, while Centureæ and Colapteæ both belong to Ligonirostres. The Nudinares are not represented in North America, and by only one group, Celeus, in any portion of the continent.

In the following account of the Picinæ, we shall not pretend to discuss the relationship of the North American species to the Picinæ in general, referring to Sundevall’s work, and the monographs of Malherbe and Cassin, for information on the subject. For our present purposes they may be conveniently, even if artificially, arranged in the following sections:—

Piceæ. Bill variable in length; the outlines above and below nearly straight; the ends truncated; a prominent ridge on the side of the mandible springing from the middle of the base, or a little below, and running out either on the commissure, or extending parallel to and a little above it, to the end, sometimes obliterated or confluent with the lateral bevel of the bill. Nostrils considerably overhung by the lateral ridge, more or less linear, and concealed by thick bushy tufts of feathers at the base of the bill. Outer posterior toe generally longer than the anterior.

Centureæ. Bill rather long; the outlines, that of the culmen especially, decidedly curved. The lateral ridge much nearest the culmen, and, though quite distinct at the base, disappearing before coming to the lower edge of the mandible; not overhanging the nostrils, which are broadly oval, rounded anteriorly, and not concealed by the bristly feathers at the base. Outer pair of toes nearly equal; the anterior rather longer.

Colapteæ. Bill rather long, much depressed, and the upper outline much curved to the acutely pointed (not truncate) tip. The commissure considerably curved. Bill without any ridges. The nostrils broadly oval, and much exposed. Anterior outer toe longest.

PLATE XLVIII.

1. Geococcyx californianus ♂ Cal., 12925.

2. Crotophaga ani. ♀ Fla., 8639.

3. Coccygus americanus. ♂ Penn., 1541.

4. Coccygus minor.

5. Coccygus erythrophthalmus. 27028.

The preceding diagnoses will serve to distinguish the three groups sufficiently for our present purposes; the bill being strongest in the Picinæ and best fitted for cutting into trees by its more perfect wedge-shape, with strengthening ridges, as well as by the lateral bevelling of both mandibles, which are nearly equal in thickness at the base, and with their outlines nearly straight. The lateral ridge is prominent, extending to the edge or end of the bill, and overhangs the nostrils, which are narrow and hidden. The Centureæ and the Colapteæ have the upper mandible more curved (the commissure likewise), the lower mandible smaller and weaker, the bill with little or no lateral bevelling. The nostrils are broadly oval and exposed. In the former, however, there is a distinct lateral ridge visible for a short distance from the base of the bill; while in the other there is no ridge at all, and the mandible is greatly curved.

In all the species of North American Woodpeckers, there is more or less red on the head in the male, and frequently in the female. The eggs of all are lustrous polished white, without any markings, and laid in hollow trees, upon a bed of chips, no material being carried in for the construction of the nest.

Section PICEÆ

With the common characters, as already given, there are several well-marked generic groups in this section of Woodpeckers which may be arranged for the United States species as follows:—

A. Posterior outer toe longer than the anterior outer one. (Fourth toe longer than third.)

a. Lateral ridge starting above the middle of the base of the bill, and extending to the tip.

1. Campephilus. Lateral ridge above the middle of the lateral profile of the bill when opposite the end of the nostrils, which are ovate, and rounded anteriorly. Bill much depressed, very long; gonys very long. Posterior outer toe considerably longer than the anterior. Primaries long, attenuated towards the tip. Spurious quill nearly half the second. Shafts of four middle tail-feathers remarkably stout, of equal size, and abruptly very much larger than the others; two middle tail-feathers narrower towards bases than towards end.¹²⁵ A pointed occipital crest.

 

2. Picus. Lateral ridge in the middle of the lateral profile opposite the end of the nostrils, which are ovate and sharp-pointed anteriorly. Bill moderate, nearly as broad as high.

Outer hind toe moderately longer than the outer fore toe. Primaries broad to the tip, and rounded. Spurious primary not one third the second quill.

3. Picoides. Lateral ridge below the middle of the profile, opposite the end of the ovate acute nostrils, which it greatly overhangs. Bill greatly depressed; lower mandible deeper than the upper. Inner hind toe wanting, leaving only three toes. Tufts of nasal bristles very full and long.

b. Lateral ridge starting below the middle of the base of the bill, and running as a distinct ridge into the edge of the commissure at about its middle; the terminal half of the mandible rounded on the sides, although the truncate tip is distinctly bevelled laterally.

4. Sphyropicus. Nostrils considerably overhung by the lateral ridge, very small, linear. Gonys as long as the culmen, from the nostrils. Tips of tail-feathers elongated and linear, not cuneate. Wings very long; exposed portion of spurious primary about one fourth that of second quill.

B. Posterior outer toe considerably shorter than the anterior outer one. (Fourth toe shorter than third).

5. Hylotomus. Bill depressed. Lateral ridge above the middle of the lateral profile near the base. Nostrils elliptical, wide, and rounded anteriorly. Tail almost as in Sphyropicus. A pointed occipital crest, as in Campephilus, and not found in the other genera.

The arrangement in the preceding diagnosis is perhaps not perfectly natural, although sufficiently so for our present purpose. Thus, Hylotomus, in having the lateral ridge extending to the end of the bill, is like Picus, but the nostrils are broader, more open, and not acute anteriorly. The tail-feathers of Sphyropicus differ greatly from those of the others in being abruptly acuminate, the points elongated, narrow, and nearly linear, instead of being gently cuneate at the ends. Campephilus and Hylotomus belong to Sundevall’s Angusticolles, with their long slender neck, and elongated occipital crest (Dryocopinæ, Cab.); the other genera to Securirostres, with shorter, thicker neck, and no crest (Dendrocopinæ, Cab.). But no two genera in the subfamily are more distinct than Campephilus and Hylotomus.

Genus CAMPEPHILUS, Gray

Campephilus, Gray, List of Genera? 1840. (Type, C. principalis.)

Megapicus, Malherbe, Mém. Ac. de Metz, 1849, 317.

Gen. Char. Bill considerably longer than the head, much depressed, or broader than high at the base, becoming somewhat compressed near the middle and gradually bevelled off at the tip. Culmen very slightly curved, gonys as concave, the curve scarcely appreciable; commissure straight. Culmen with a parallel ridge on each side, starting a little above the centre of the basal outline of the bill, the ridge projecting outwards and downwards, and a slight concavity between it and the acute ridge of the culmen. Gonys considerably more than half the commissure. Nostrils oval below the lateral ridge near the base of the bill; concealed by the bristly feathers directed forward. Similar feathers are seen at the sides of the lower jaw and on the chin.

Campephilus principalis.

3869 ♂

Feet large; outer hind toe much longest; claw of inner fore toe reaching to middle of outer fore claw; inner hind toe scarcely more than half the outer one; its claw reaching as far as the base of the inner anterior claw, considerably more than half the outer anterior toe. Tarsus rather shorter than the inner fore toe. Tail long, cuneate; shafts of the four middle feathers abruptly much larger than the others, and with a deep groove running continuously along their under surface; webs of the two middle feathers deflected, almost against each other, so that the feathers appear narrower at the base than terminally. Wings long and pointed, the third, fourth, and fifth quills longest; sixth secondary longest, leaving six “tertials,” instead of three or four as usual; primaries long, attenuated. Color continuous black, relieved by white patches. Head with a pointed occipital crest.

This genus embraces the largest known kind of Woodpecker, and is confined to America. Of the two species usually assigned to it, only one occurs within the limits of the United States, C. imperialis, given by Audubon, and by subsequent authors on his credit, really belonging to Southern Mexico and Central America. The diagnoses of the species are as follows:—

Common Characters. Bill ivory-white. Body entirely glossy blue-black. A scapular stripe, secondaries, ends of inner primaries, and under wing-coverts, white. Crest scarlet in the male, black in the female.

1. C. principalis. A white stripe on each side of the neck. Bristly feathers at the base of the bill white.

White neck-stripe not extending to the base of the bill. Black feathers of crest longer than the scarlet. Wing, 10.00; culmen, 2.60. Hab. Gulf region of United States … var. principalis.

White stripe reaching the base of the bill. Scarlet feathers of crest longer than the black. Wing, 9.50; culmen, 2.40. Hab. Cuba … var. bairdi.¹²⁶

2. C. imperialis. No white stripe on the sides of the neck. More white on the wings. Bristly feathers at the base of the bill black. Hab. South Mexico; Guatemala.

Sp. Char. Fourth and fifth quills equal; third a little shorter. Bill horn-white. Body entirely of a glossy blue-black (glossed with green below); a white stripe beginning half an inch posterior to the commissure, and passing down the sides of the neck, and extending down each side of the back. Under wing-coverts, and the entire exposed portion of the secondary quills, with ends of the inner primaries, bristles, and a short stripe at the base of the bill, white. Crest scarlet, upper surface black. Length, 21.00; wing, 10.00. Female similar, without any red on the head, and with two spots of white on the end of the outer tail-feather.

Hab. Southern Atlantic and Gulf States. North to North Carolina and mouth of the Ohio; west to Arkansas and Eastern Texas. Localities: Brazos and Trinity Rivers, Texas (Dresser, Ibis, 1865, 468, breeds).

In the male the entire crown (with its elongated feathers) is black. The scarlet commences just above the middle of the eye, and, passing backwards a short distance, widens behind and bends down as far as the level of the under edge of the lower jaw. The feathers which spring from the back of the head are much elongated above; considerably longer than those of the crown. In the specimen before us the black feathers of the crest do not reach as far back as the scarlet.

Reference has already been made to the Cuban variety of the Ivory-billed Woodpecker named C. bairdi by Mr. Cassin, and differing in smaller size; extension of the white cheek-stripe to the very base of the bill, and the excess in length of the upper black feathers of the crest over the scarlet. These features appear to be constant, and characteristic of a local race.

For the reasons already adduced, we drop C. imperialis from the list of North American birds, although given as such by Audubon.

Campephilus principalis.

Habits. So far as we have information in regard to the geographical distribution of the Ivory-billed Woodpecker, it is chiefly restricted in its range to the extreme Southern States, and especially to those bordering on the Gulf of Mexico. Wilson states that very few, if any, are ever found north of Virginia, and not many even in that State. His first specimen was obtained near Wilmington, N. C. It is not migratory, but is a resident where found.

Mr. Audubon, who is more full than any other writer in his account of this bird, assigns to it a more extended distribution. He states that in descending the Ohio River he met with it near the confluence of that river with the Mississippi, and adds that it is frequently met with in following the windings of the latter river either downwards towards the sea, or upwards in the direction of the Missouri. On the Atlantic he was inclined to make North Carolina the limit of its northern distribution, though now and then individuals of the species have been accidentally met with as far north as Maryland. To the westward of the Mississippi he states that it is found in all the dense forests bordering the streams which empty into it, from the very declivities of the Rocky Mountains. The lower parts of the Carolinas, Georgia, North Florida, Alabama, Louisiana, and Mississippi, are, however, its favorite resorts, and in those States it constantly resides.

It was observed by Dr. Woodhouse in the timber on the Arkansas River, and in Eastern Texas, but quite rarely in both places. It was not, however, met with in any other of the government expeditions, either to the Pacific, in the survey of the railroad routes, or in that for the survey of the Mexican boundary line. It is given as a bird of Cuba by De la Sagra, in his catalogue of the birds of that island, as observed by him, October, 1850, and by Dr. John Gundlach, in his list of the birds that breed in Cuba. It is not mentioned by Gosse among the birds of Jamaica, nor by the Newtons as found in St. Croix. As it is not a migratory bird, it may be regarded as breeding in all its localities, except where it is obviously an accidental visitant.

Wilson, who never met with the nest of this Woodpecker, states, on the authority of reliable informants, that it breeds in the large-timbered cypress swamps of the Carolinas. In the trunks of these trees at a considerable height from the ground, both parents working alternately, these birds dig out a large and capacious cavity for their eggs and young. Trees thus dug out have frequently been cut down with both the eggs and the young in them. The hole was described to Wilson as generally a little winding, to keep out the rain, and sometimes five feet deep. The eggs were said to be generally four, sometimes five in number, as large as pullets’, pure white, and equally thick at both ends. The young make their appearance about the middle or end of June.

Mr. Audubon, whose account of the breeding-habits of the Ivory-bill is given from his own immediate observations, supplies a more minute and detailed history of its nesting. He states that it breeds earlier in spring than any other species of its tribe, and that he has observed it boring a hole for that purpose as early as the beginning of March. This hole he believed to be always made in the trunk of a live tree, generally an ash or a hackberry, and at a great height. It pays great regard to the particular situation of the tree and the inclination of the trunk, both with a view to retirement and to secure the aperture against rains. To prevent the latter injury, the hole is generally dug immediately under the protection of a large branch. It is first bored horizontally a few inches, then directly downward, and not in a spiral direction, as Wilson was informed. This cavity is sometimes not more than ten inches in depth, while at other times it reaches nearly three feet downward into the heart of the tree. The older the bird, the deeper its hole, in the opinion of Mr. Audubon. The average diameter of the different nests which Mr. Audubon examined was about seven inches in the inner parts, although the entrance is only just large enough to admit the bird. Both birds work most assiduously in making these excavations. Mr. Audubon states that in two instances where the Woodpeckers saw him watching them at their labors, while they were digging their nests, they abandoned them. For the first brood, he states, there are generally six eggs. These are deposited on a few chips at the bottom of the hole, and are of a pure white color. The young may be seen creeping out of their holes about a fortnight before they venture to fly to any other tree. The second brood makes its appearance about the 15th of August. In Kentucky and Indiana the Ivory-bill seldom raises more than one brood in a season. Its flight is described by Audubon as graceful in the extreme, though seldom prolonged to more than a few hundred yards at a time, except when it has occasion to cross a large river. It then flies in deep undulations, opening its wings at first to their full extent, and nearly closing them to renew their impulse. The transit from tree to tree is performed by a single sweep, as if the bird had been swung in a curved line from the one to the other.

Except during the love-season it never utters a sound when on the wing. On alighting, or when, in ascending a tree, it leaps against the upper parts of the trunk, its remarkable voice may be constantly heard in a clear, loud, and rather plaintive tone, sometimes to the distance of half a mile, and resembling the false high note of a clarionet. This may be represented by the monosyllable pait thrice repeated.

The food of this Woodpecker consists principally of beetles, larvæ, and large grubs. They are also especially fond of ripe wild grapes, which they eat with great avidity, hanging by their claws to the vines, often in the position of a Titmouse. They also eat ripe persimmons, hackberries, and other fruit, but are not known to disturb standing corn nor the fruits of the orchard.

These birds attack decaying trees so energetically as often to cause them to fall. So great is their strength, that Audubon has known one of them to detach, at a single blow, a strip of bark eight inches long, and, by beginning at the top branch of a dead tree, tear off the bark to the extent of thirty feet in the course of a few hours, all the while sounding its loud notes.

Mr. Audubon further states that this species generally moves in pairs, that the female is the least shy and the most clamorous, and that, except when digging a hole for the reception of their eggs, they are not known to excavate living trees, but only those attacked by worms. When wounded, they seek the nearest tree, and ascend with great rapidity by successive hops. When taken by the hand, they strike with great violence, and inflict severe wounds with their bills and claws.

Mr. Dresser states that these birds were found on the Brazos River, and also on the Trinity, where they were by no means rare.

Wilson dwells at some length and with great force upon the great value of these birds to our forests. They never injure sound trees, only those diseased and infested with insects. The pine timber of the Southern States is often destroyed, thousands of acres in a season, by the larvæ of certain insects. In Wilson’s day this was noticeable in the vicinity of Georgetown, S. C., and was attributed by him to the blind destruction of this and other insect-eating birds.

An egg of this species (Smith. Coll., No. 16,196) taken near Wilmington, N. C., by Mr. N. Giles, measures 1.35 inches in length by .95 of an inch in breadth. It is of a highly polished porcelain whiteness, and is much more oblong in shape and more pointed than are the eggs of Hylotomus pileatus.

Genus PICUS, Linnæus

Picus, Linn. Syst. Nat. 1748. (Type, Picus martius, L.)

Picus villosus.

884 ♂

Gen. Char. Bill equal to the head, or a little longer; the lateral ridges conspicuous, starting about the middle of the base of the bill; the basal elongated oval nostrils nearest the commissure; the ridges of the culmen and gonys acute, and very nearly straight, or slightly convex towards the tip; the bill but little broader than high at the base, becoming compressed considerably before the middle. Feet much as in Campephilus; the outer posterior toe longest; the outer anterior about intermediate between it and the inner anterior; the inner posterior reaching to the base of the claw of the inner anterior. Tarsus about equal to the inner anterior toe; shorter than the two other long toes. Wings rather long, reaching to the middle of the tail, rather rounded; the fourth and fifth quills longest; the quills rather broad and rounded.

In the genus Picus, as characterized above, are contained several subdivisions more or less entitled to distinct rank, and corresponding with peculiar patterns of coloration. Thus, taking the P. villosus as the type, P. borealis has proportionally much longer primaries; the spurious primary smaller; the bill is considerably more attenuated, and even concave in its lateral outlines. The wings are still longer in P. albolarvatus. The species may be arranged as follows:—

A. Black above, and white beneath. Wings spotted with white; a black maxillary stripe.

a. Two white stripes on the side of the head, one above, and the other below, the ear-coverts, which are mostly black. First quill shorter than sixth. Tail-feathers broad and obtuse at ends, the narrowed tips of middle feathers very short.

DRYOBATES, Boie. Middle of back streaked longitudinally and continuously with white. Maxillary and auricular black stripes not confluent; the latter running into the black of the nape. Beneath white without spots. Red of head confined to a narrow nuchal band.

All the quills, with middle and greater wing-coverts, with large white spots. Hab. Eastern North America … var. villosus.

Innermost quills and some of the coverts entirely black, or unspotted with white. Remaining spots reduced in size. (Var. jardini similar, but much smaller, 7.00, and lower parts smoky-brown.) Hab. Middle and western North America, and south to Costa Rica … var. harrisi.

2. P. pubescens. Outer tail-feather white, with transverse black bands; length about 6.25.

All the quills, with middle and greater wing-coverts, with large white spots. Hab. Eastern North America … var. pubescens.

Innermost quills and some of the coverts entirely black; remaining white spots reduced in size. Hab. Western North America … var. gairdneri.

DYCTIOPICUS, Bon. Whole back banded transversely with black and white. Beneath white, with black spots on sides. Maxillary and auricular black stripes confluent at their posterior ends, the latter not running into the nape. In the males at least half of top of head red. Length, about 6.50.

3. P. scalaris. Anterior portion of the back banded with white; lores and nasal tufts smoky brown. Black stripes on sides of the head very much narrower than the white ones, and not connected with the black of the shoulders. Male with the whole crown red.

Outer web of lateral tail-feathers barred with black to the base. White bands on back exceeding the black ones in width; red of the crown very continuous, on the forehead predominating over the black and white. (Sometimes the black at base of inner web of lateral tail-feather divided by white bars.) Hab. Southern and Eastern Mexico, and Rio Grande region of United States … var. scalaris.

Outer web of lateral tail-feather barred with black only toward end. Red of crown much broken anteriorly, and in less amount than the black and white mixed with it. White bands of the back not wider, generally much narrower than the black ones.

Bill, .90; tarsus, .70. Red of crown extending almost to the bill. Hab. Western Mexico, up to Western Arizona … var. graysoni.

Bill, 1.10; tarsus, .75. Red of crown disappearing about on a line above the eye. Hab. Cape St. Lucas … var. lucasanus.

4. P. nuttalli. Anterior portion of back not banded with white; lores and nasal tufts white. Black stripes on side of the head very much broader than the white ones, and connected by a narrow strip with the black of the shoulders. Male with only the nape and occiput red. Hab. California (only).

b. One white stripe, only, on side of head, and this occupying whole auricular region. Tail-feathers narrowed at ends, the points of the middle ones much elongated. First quill longer than sixth. Bill very small, much shorter than head.

PHRENOPICUS, Bonap. Back and wings transversely banded with black and white, and sides spotted with black, as in Dyctiopicus.

5. P. borealis. Red of male restricted to a concealed narrow line on each side of the occiput, at the junction of the white and black. Maxillary black stripe very broad and conspicuous, running back to the series of black spots on sides of breast. Three outer tail-feathers more or less white, with a few bars of black near their ends, principally on inner webs. Hab. South Atlantic States.

B. Body entirely continuous black; head all round immaculate white. First quill shorter than sixth.

XENOPICUS, Baird. Tail and primaries as in “A,” but much more lengthened. Bill as in Dryobates, but more slender.

6. P. albolarvatus. Red of male a narrow transverse occipital crescent, between the white and the black. Basal half, or more, of primaries variegated with white, this continuous nearly to the end of outer webs; inner webs of secondaries with large white spots toward their base. Hab. Sierra Nevada and Coast Ranges, Pacific Province, United States.

Subgenus DRYOBATES, Boie

Dryobates, Boie, 1826. (Type, Picus pubescens, fide Cabanis, Mus. Hein.)

Trichopicus, Bonap. 1854.

Trichopipo, Cab. & Hein. Mus. Hein. 1863, 62.

According to Cabanis, as above cited, Dryobates, as established by Boie in 1826, had the Picus pubescens as type, although extended in 1828 to cover a much wider ground. As a subgeneric name, therefore, it must take preference of Trichopicus of Bonaparte, which, like all the allied names of this author, Cabanis rejects at any rate as hybrid and inadmissible.
