Synopsis of the Varieties.

COMMON CHARACTERS. Grayish-brown above, with a more or less

appreciable rufous tinge on the crown. A patch covering the

throat, ochraceous or white, contrasting with the surrounding

portions, and encircled more or less completely, especially

posteriorly, by dusky spots; lores like the chin. Crissum

deep ochraceous, the lower part of abdomen tinged more or

less with the same.

Kieneria fusca_, BP. C. R. XL, 1855, 356.

SP. CHAR. Above dull olive-brown; the top of head having the

central portion of feathers tinged (inconspicuously and

obscurely) with rufous. Chin and throat pale rufous,

bordered by dusky streaks; a single dusky spot in lower part

of jugulum. Belly and flanks behind, anal region and

crissum, rather darker rufous. Sides grayish-olive, lighter

than the back, tingeing the breast, and leaving only a small

patch in the centre of under parts white, shading into the

surrounding ashy-brown. Fourth and fifth quills longest;

first shorter than ninth, or than secondaries.

_Dimensions_ (prepared specimen): Total length, 7.75; wing,

3.80; tail, 4.20; exposed portion of first primary, 2.30; of

longest (measured from exposed base of first primary), 3.03.

Bill: Length from forehead, .65; from nostril, .40. Legs:

Tarsus, .95; middle toe and claw, 1.00; hind toe and claw,

.68; claw alone, .36. _Hab._ Highlands of Mexico.

The specimen described is from the city of Mexico, and

belongs to Mr. G. N. Lawrence; others before us are from

Temiscaltepec (the original locality of Swainson’s type),

Guadalaxara, and Tepic.

While admitting the strong probability that the different

brown _Pipilos_ with rufous throat bordered by black spots,

_P. fuscus_, _crissalis_, _mesoleucus_, _albigula_, and

probably even _albicollis_, are geographical modifications

of the same original type, the large collection before us

vindicates the action of those who have referred the

California species to that described by Swainson as

_fuscus_, and who have distinguished the _P. mesoleucus_

from both. The original description of _fuscus_ agrees

almost exactly with _crissalis_, both actually scarcely

separable; while the _mesoleucus_, intermediate in

geographical position, is decidedly different from either.

The relationships of these different forms will be found

expressed in the general diagnosis already given.

Two descriptions given by Swainson, copied below, of the _P.

fuscus_, differ somewhat from each other, and may not have

been taken from the same specimen. The identification of

either with _P. mesoleucus_ would be a difficult matter;

while the first one expresses the peculiar characters of

_crissalis_ more nearly than any other. The statement of

“white beneath,” without any qualification, applies better

to _mesoleucus_ than to others, but the “pale rufous tinge”

observable in _crissalis_ and _fuscus_ is very different

from the abruptly defined chestnut cap of _mesoleucus_.

_Pipilo fuscus_, SWAINSON, Phil. Mag. I, 1827, 434. “Gray,

beneath paler; throat obscure fulvous, with brown spots;

vent ferruginous. Length, 8.00; bill, .70; wings, 3.50;

tail, 4.00; tarsi, .90; hind toe and claw, .70.” _Hab._

Table land; Temiscaltepec.

_Pipilo fuscus_, SWAINSON, Anim. in Men. 1838, 347.

“Grayish-brown above; beneath white; chin and throat

fulvous, with dusky spots; under tail-coverts fulvous; tail

blackish-brown, unspotted. Bill and legs pale, the latter

smaller, and the claws more curved than in any other known

species; crown with a pale rufous tinge. Length, 7.50;

wings, 3.50; tail, 4.00; tarsus, .90; middle toe and claw

the same; hinder toe, .65. Rather smaller than _maculata_.”

[25] _Pipilo albicollis_, SCLATER. Above uniform

olivaceous-brown; the cap not differently colored. Lores,

chin, and throat white, the two last bordered and defined by

dusky spots; jugulum and breast white, the former clouded

with olivaceous, and with a dusky blotch in middle; middle

of throat crossed by an olivaceous band which curves round

on each side under the ear-coverts; sides grayish. Flanks

behind, anal region, and crissum, rufous. Middle

wing-coverts with a whitish bar across their tips. Fourth

and fifth quills longest; first shorter than ninth and

secondaries. Length, 7.00; wing, 3.30; tail, 3.70. Bill and

legs light. _Hab._ Central Mexico.

This “species” may fairly be considered as one extreme of

the series of which _P. crissalis_ is the other; and differs

from the rest merely in a greater amount of white, and the

absence of rufous tinge on top of head. The fulvous of

throat is concentrated in a band across its middle portion,

leaving chin and lower throat white; this, however, is

foreshadowed in the paler chin of _mesoleucus_, and the

whitish lower throat of _albigula_. The uniformity of

coloring above is nearly equalled by that of _P. crissalis_.

The whitish band across the middle wing-coverts is the most

positive character.

[Illustration: _Pipilo fuscus_, var. _crissalis_.]

SP. CHAR. Above dark olive-brown, the crown with a very slight tinge

of scarcely appreciable dark rufous. Under parts with the color

somewhat similar, but of a lighter shade, and washed with grayish;

middle of the belly only whitish; the under tail-coverts pale rufous,

shading into lighter about the vent and sides of lower belly; chin and

throat well-defined pale rufous, margined all round by brown spots, a

few of them scattered within the margin. Eyelids and sides of head,

anterior to the eye, rufous like the throat. One or two feathers on

the lower part of the breast with a concealed brown blotch. Outer

primary not edged with white. Fifth quill longest; first shorter than

ninth, or even than secondaries. Bill pale brown, darker above; legs

light. Length, 8.50 inches; wing, 4.00; tail, 4.60.

HAB. Coast region of California.

The bill is sinuated, as in _P. aberti_, differing from that of _P.

erythrophthalmus_.

This race is very similar to the original _P. fuscus_ of Mexico, the

original description of Swainson answering almost exactly. It is,

however, considerably larger; the proportions of wing are similar; and

there is no decided indication of whitish in the middle of the body

beneath, such as is always distinctly appreciable in _fuscus_, and

still more in _mesoleucus_.

A young bird differs but little from the adult except in having

obsolete dusky streaks below; the upper parts are uniform.

HABITS. The Brown, or Cañon Finch of California is found nearly

throughout the State of California. Mr. Xantus obtained it at Fort

Tejon, and Mr. Ridgway observed it among the chaparrals on the

foothills of the western slope of the Sierras.

Dr. Cooper considers the name of Cañon Finch ill applied to this

species, as it is equally plentiful in level districts, wherever trees

and shrubbery exist. He regards it as one of the most abundant and

characteristic birds of California, residing in all the lower country

west of the Sierras, and extending up the slopes of the Coast Range to

the height of three thousand feet. They are said to have habits very

similar to those of all the other species, living much upon the

ground, and seeking their food among the dead leaves, which they

greatly resemble in color. This resemblance Dr. Cooper regards as a

great protection to them from Hawks; their hues also correspond with

those of the earth and the dusky foliage during most of the year. They

are thus less conspicuous in the light, and they venture more

fearlessly forth and feed in open grounds.

They have but little song, and only utter a few faint chirps and

hurried notes, as they sit perched upon some low bush, in the spring.

At San Diego Dr. Cooper saw the first nest with eggs on April 17, but

some birds had laid much earlier, as he found young hatched by the

20th. He afterwards observed other nests, all of which were built in

bushes, from two to four feet from the ground, and all but one

contained three eggs; the other had four. He has found them built in

low trees, and one in a vine growing over the porch of a house. The

nest is formed of coarse twigs, bark, and grass, is thick and large,

and is lined with fine root-fibres and finer grasses. The eggs are

pale blue, spotted with purplish-brown blotches, mostly small and

scattered. He gives the measurement of the eggs as .90 by .65 of an

inch. In the more northern part of the State they are said to lay four

eggs oftener than three. They are supposed by him to have two broods

in a season.

Colonel McCall has no doubt that they are found throughout California,

as he has met with them from the upper waters of the Sacramento to the

mouth of the Gila; the former having its origin in the extreme north,

and the latter touching the extreme southern boundary of the State. It

is most abundant south of Santa Barbara.

Colonel McCall states that its habits and manners differ somewhat from

those of the common Towhee and the Arctic Finches. Its flight is more

even and regular, and is without that violent jerking of the tail from

side to side, which gives such a singular appearance of awkwardness to

the movements of the Towhee. It is less shy and suspicious than the

Arctic. It is also much less decidedly a Ground Finch than either of

the others. Its favorite abode he found to be the vicinity of

watercourses, where it is generally to be seen in pairs, though he

has, at times, surprised eight or ten together under the shade of a

large bush at noon in a summer day, when he has had no difficulty in

procuring three or four specimens before the party dispersed. It is at

all times a familiar bird, boldly coming into the roads to feed, and

permitting a close approach. If compelled to retreat, it darts

suddenly into the thicket, but returns as soon as the cause of alarm

has disappeared. Near Santa Barbara he found thirty or forty of these

birds, in the month of July, dispersed over an old field of some five

acres in extent, contiguous to a sea-beach, through which flowed a

small stream of fresh water. They were feeding on the ground,

sheltered by a rank growth of weeds. When one was flushed it flew into

a neighboring tree instead of seeking shelter again in the weeds. The

young at that time were fully fledged, and scarcely differed in the

color of their plumage from the adults.

Dr. Heermann once met with a nest of this bird built in a grapevine

overhanging the Sacramento River. He describes the eggs of this

species as differing entirely from any of this genus he had ever met

with, and as having so great a resemblance to the eggs of the three

different species of Blackbirds inhabiting California that they were

liable to be confounded with them unless marked when taken from the

nest.

Dr. Newberry, who found this bird very common in the Sacramento

Valley, states that when he first met with it, a strange bird to him,

its habit of scratching among the dry leaves under the bushes, as well

as its long tail and jerking flight from one clump of bushes to

another, at once indicated to him its affinities.

Among the memoranda made by Mr. Xantus at Fort Tejon are the following

in reference to this species: “474, nest and two eggs, found May 19 on

a small thorn-bush in a very dark thicket, about six feet from the

ground; 1,675, nest and one egg, on a thick thorny bush, six feet from

the ground; 1,851, nest and two eggs, May 12, on a rose-bush, four

feet from the ground, eggs already incubated.”

The eggs of this species measure one inch by .75, have a light ground

of robin-blue, and are spotted and blotched with varying shades of

dark and light purple. In some the color of the blotches is so deep as

not to be distinguishable from black, except in a strong light. The

lighter shades are a faint lavender.

SCLATER & SALVIN, P. Z. S. 1869, 361 (city of Mexico).

SP. CHAR. Above very dull olivaceous-brown, with a grayish tinge; hood

dull chestnut, conspicuously different from the back. Sides like the

back, but paler; posteriorly, and about the vent and under

tail-coverts, pale brownish-red. The ashy olive-brown of the sides

scarcely meeting across the breast, the lower portion of which, with

the upper belly, is rather pure white. The loral region, chin, throat,

and upper part of the breast, pale yellowish-rufous, finely spotted on

the sides and more coarsely across the breast with brown; an obscure

spot in the middle of the breast; edge of outer primary white. Bill

pale brown; legs flesh-color; first quill about equal to eighth, third

and fourth longest. Length, 8.50 inches; wing, 3.80; tail, 4.70.

HAB. Valley of Upper Rio Grande and across to the Gila River. East to

Santa Caterina, New Leon.

This race is similar in general appearance to _P. crissalis_, but the

olive-brown and rufous are both of a lighter shade. The crown is of a

decided rufous, conspicuously different from the back, instead of

nearly the same tint. The light reddish under the head is wider

throughout, and extends down to the upper part of the breast, blending

with the colors of the breast and belly, instead of being narrower,

more sharply defined, and restricted to the chin and throat; it is

palest anteriorly, the chin and lore being almost white. The isolated

larger spot on the breast is more conspicuous; the breast and belly

are quite pure white, shaded with obsolete brownish blotches, instead

of being uniform grayish-brown, with only an approach to whitish in

the very middle. The edges of the wing and tail feathers are a good

deal lighter, the outer web of the first primary being sharply edged

with pure white, instead of obscure grayish-brown. The size generally

is rather smaller, the wings more pointed.

Compared with _P. fuscus_, we find the tail decidedly longer; the wing

more pointed; the first quill about equal to the eighth, instead of

shorter than the secondaries. The colors generally are paler; the cap

of head bright distinct rufous in strong contrast with the other

plumage, instead of being only very obscurely tinged with that color.

The white of belly is purer, and extends farther forward, displacing

the ashy tinge almost to the buff of the throat.

If we consider all the brown _Pipilos_ as modifications of one

primitive species, it will be well to consider the Arizonan and New

Mexican bird as the central figure around which the others are

grouped. The common character will then be varied in the California

race, _crissalis_, by the absence of decided rufous on crown, a darker

shade of color, and an extension of the gray of sides over the whole

under parts, almost entirely displacing the white. The wing is more

rounded, and the general dimensions larger southward on the central

plains of Mexico; the general tints are almost precisely as in the

California bird, except that the white of belly is very evident; but

the chestnut cap and extended whiteness of belly, together with the

pointed wing of _mesoleucus_, are wanting. In _P. albigula_ of Cape

St. Lucas we have the general characters of _mesoleucus_, with paler

colors, more restricted spots encircling throat, and a tendency to

white in its lower part. In this it approaches _albicollis_ of

Southwestern Mexico.

HABITS. This little-known form was first obtained by Dr. Kennerly,

naturalist to the Pacific Railroad Expedition on the 35th parallel,

under Lieutenant Whipple. He met with it at Bill Williams Fork, in

Arizona, February 5, 1854. It was described by Professor Baird the

following June. Dr. Kennerly furnished at the time no information in

regard to its habits.

Dr. Heermann, in his Report on the birds observed in Lieutenant

Parke’s expedition, mentions having met with this species in the

vicinity of Tucson. Its habits, so far as he could judge of them from

his opportunities, appeared very similar to those of _Pipilo aberti_.

Lieutenant Couch met with this species at Santa Catalina, Mexico, in

April, 1853, but furnishes no information in reference to its manners.

Mr. J. H. Clark, who obtained a specimen near the Copper Mines of the

Mimbres, states that they were met with in abundance in the deep

valleys or cañons of that region. They were almost always in or about

the thick clumps of bushes, several usually being in company.

Dr. Kennerly, who met with them on a second trip, in June, 1855, near

Los Nogales, in Mexico, speaks of them as not very common in that

region. He found them preferring the dense bushes in the valleys. When

approached, they became very restless, flying from one bush to

another, accompanying their motions with very peculiar notes, which he

does not describe.

Dr. Coues found this species abundantly distributed throughout the

warmer portions of New Mexico and Arizona, from the valley of the Rio

Grande to that of the Colorado. He did not observe any at Fort

Whipple, though they were found breeding some twenty-five miles to the

southward. He found them associating freely with _Pipilo aberti_, and

inhabiting the same regions. The two birds have very similar habits.

Dr. Henry also states that this species is common in New Mexico both

summer and winter, and, so far as he has observed, dwelling almost

entirely among the mountains. It appeared to him very retiring in its

habits, and seemed to prefer the cañons. He has seldom, if ever,

observed it far from shady gorges, where, like its relative of the

Eastern States, the Towhee Bunting, it passes the greater part of its

time on the ground, and is generally accompanied by its congener, the

Arctic Finch. When disturbed, it seeks the thickest cover, though it

is by no means shy or difficult to approach. Its nest is usually

constructed in the branches of a thick cedar or dwarf oak, and he has

never known it to produce more than one brood in a season.

Dr. Cooper states that these birds are very abundant in Southern

Arizona, that their habits closely resemble those of _P. aberti_, and

that their eggs are similar to those of _Pipilo fuscus_.

Pipilo fuscus, var. albigula, BAIRD.

CAPE TOWHEE.

_Pipilo albigula_, BAIRD, P. A. N. S. Nov. 1859, 305 (Cape St.

Lucas).—ELLIOT, Illust. Am. Birds, I, pl. xv (“= _P.

mesoleucus_”).—COOPER, Orn. Cal. 1, 248.

SP. CHAR. Similar to var. _mesoleucus_, having, like it, a distinctly

rufous crown and white abdomen. Differing, however, in the following

respects: The pale ochraceous gular area is more sharply defined, the

buff being confined within the encircling series of dusky spots; the

buff is palest posteriorly, instead of directly the opposite. The

rufous of the crissal region is more restricted, only tingeing the

anal region instead of invading the lower part of the abdomen, the

white beneath also is shifted farther back, covering the abdomen

alone, instead of the breast, the whole jugulum being distinctly ashy,

like the sides. Wing, 3.80; tail, 4.25.

HAB. Cape St. Lucas.

A very large series of specimens from Cape St. Lucas agree in

possession of the characters pointed out above, distinguishing them

from _mesoleucus_, to which race the present one is most nearly

related.

HABITS. The White-throated or Cape Towhee of Cape St. Lucas was first

met with by Mr. Xantus in the southern extremity of the peninsula of

Lower California, and described by Professor Baird in 1859. Its close

resemblance to _P. mesoleucus_ suggests an equal similarity as to its

habits, in regard to which we possess no actual knowledge. Mr. Xantus

has furnished us with no memoranda as to the manners of the bird. We

have only the brief mention among his notes to the effect that No.

4,855 is the nest with four eggs of this _Pipilo_, found in a wild

_Humulus_ thicket; and that No. 5,076 is a nest with eggs of the same,

found in a thicket of wild roses in the garden fence.

Judging from the large number of the nests and eggs of this species

collected by that gentleman at Cape St. Lucas, it would seem to be

very abundant in that locality.

The eggs of this variety measure .95 of an inch in length and .72 in

breadth. They bear a strong resemblance to those of the _P. fuscus_,

but the markings are darker and more distinctly defined, standing out

with a clear and striking effect, in marked contrast with the light

background. The ground-color of the egg is a light tint of robin-blue.

The markings of dots, dashes, and lines are all about the larger end,

and are of a deep dark shade of purplish-brown, so dark as, except in

a strong light, to be undistinguishable from black.
