In the accompanying cut we give outline of the bill of the two

varieties of _Pyranga æstiva_ as compared with a near ally, _P.

saira_, of South America. (13,190, _P. æstiva_; 34,344, _P. æstiva_

This species is one of wide distribution; its habitat in the United

States including the “Eastern Province,” north to Nova Scotia, and

west toward the Rocky Mountains, along the streams watering the

plains, through Texas, into Eastern Mexico, Central America, and the

northern part of South America, as well as some of the West India

islands.

In the different regions of its habitat the species undergoes

considerable variations as regards shades of color and proportions.

Specimens from Texas and Eastern Mexico exhibit a decided tendency to

longer bills and more slender forms than those of the Eastern United

States; the tails longer, and colors rather purer. In Central America

and New Granada the species acquires the greatest perfection in the

intensity and purity of the red tints, all specimens being in this

respect noticeably different from those of any other region.[107]

Specimens in the collection of the Smithsonian Institution, from Peru

(39,849 ♂, 39,849 ♂, and 39,850 ♀, head-waters Huallaga River), are

undistinguishable from those killed in the eastern United States.

The young male exhibits a variegated plumage, the red appearing in

patches upon the other colors of the female; in its changing plumage,

the red generally predominates on the head, and often individuals may

be seen with none anywhere else. In this condition there appears to be

a great resemblance to the _P. erythrocephala_ (see synoptical table),

judging from the description, but which appears to be considerably

smaller, and perhaps has the red of the head more continuous and

sharply defined.

The young male in first summer resembles the female, but has the

yellow tints deeper, the lower tail-coverts approaching orange.

HABITS. The Summer Redbird is found chiefly in the Southern States, as

far north as Southern New Jersey and Illinois. Mr. Audubon speaks of

their occurring in Massachusetts, but Mr. Lawrence has never known of

their having been found farther north than the Magnolia Swamps near

Atlantic City, N. J. One or two recent instances of the capture of

these birds in Massachusetts, as also in New Brunswick and Nova

Scotia, have occurred, but these must be regarded as purely accidental.

This species is said by Mr. Salvin to enjoy an almost universal range

throughout Guatemala. It occurred in December at the mouth of the Rio

Dulce, in the pine ridges near Quisigua, and along the whole road from

Isabel to Guatemala, a distance of eighty leagues.

Mr. C. W. Wyatt met with these birds also, in all varieties of

plumage, throughout Colombia, South America, at Herradura, Cocuta

Valley, and Canta. Mr. Boucard obtained them at Plaza Vicente, Mexico.

Dr. Woodhouse observed this species throughout the Indian Territory,

Texas, and New Mexico, where it seemed solitary in its habits,

frequenting the thick scrubby timber. It has been known to breed at

various points in Florida, Georgia, South Carolina, Louisiana, and

Texas. To the northward it breeds more or less abundantly, as far as

Washington, D. C., on the east, and Southern Illinois and Kansas on

the west, being much more common in the Mississippi Valley than in the

States on the Atlantic in the same parallel of latitude.

Mr. Dresser found it quite common about San Antonio, Texas, during the

summer season, arriving there about the middle of April, which is just

about the period at which the three specimens were taken near Boston.

It is comparatively rare in Pennsylvania, though abundant in the

southern counties of New Jersey, and in Delaware, Eastern Maryland,

and Virginia. It is also abundant in the Carolinas, in Georgia,

Florida, and the Gulf States.

Wilson, in describing the nest and eggs of this species, has evidently

confounded them and some of their habits with those of the Blue

Grosbeak. Their eggs are not light-blue, nor are the nests, so far as

I know, as described by him. Audubon and Nuttall copy substantially

his errors.

The food of this species during the spring and early summer is chiefly

various kinds of large coleopterous insects, bees, wasps, and others.

Later in the season, when whortleberries are ripe, they feed chiefly

on these and other small fruit. In taking its food it rarely alights

on the ground, but prefers to capture its insects while on the wing.

The usual note of this bird, which Mr. Audubon pronounces unmusical,

resembles the sounds “_chicky-chucky-chuck_.” The same writer states

that during the spring this bird sings pleasantly for nearly half an

hour in succession, that its song resembles that of the Red-eyed

Vireo, and that its notes are sweeter and more varied and nearly equal

to those of the Orchard Oriole.

The late Dr. Gerhardt of Varnell’s Station, in Northern Georgia,

informed me that these birds are quite common in that section of

country. The nest is usually built on one of the lower limbs of a

post-oak, or in a pine sapling, at a height of from six to twenty

feet. They are usually constructed toward the extremity of the limb,

and so far from the trunk as to be very difficult of access. They are

generally built from the middle to the end of May. The eggs are four

in number.

In Southern Illinois, according to Mr. Ridgway, the Summer Redbird

arrives about the 20th of April, staying until the last of September.

It is more abundant than the Scarlet Tanager, and much less retiring

in its habits, frequenting the open groves instead of the deeper woods

and the forests of the bottom-lands, being especially attached to the

parks and groves within the towns. From its similarity in appearance,

manners, and notes to the Scarlet Tanager, it is seldom distinguished

by the common people from that bird, and those who notice the

difference in color between the two generally consider this the

younger stage of plumage of the black-winged species. Its song is said

to be somewhat after the style of the Robin, but in a firmer tone and

more continued. It differs from the song of the _P. rubra_ in being

more vigorous, and delivered in a manner less faltering. Its ordinary

note of anxiety when the nest is approached is a peculiar

_pa-chip´it-tūt-tūt-tūt_, very different from the weaker _chip´-al,

rā-rēē_ of the _P. rubra_. The nest is placed on a low horizontal or

drooping branch, near its extremity, the tree being generally an oak,

or sometimes a hickory, and situated near the roadside or at the edge

of a grove. In its construction it is described as very thin, though

by no means frail, permitting the eggs to be seen through the

interstices from below. Mr. Ridgway never found more than three eggs

in one nest.

A nest of this species (Smith. Coll., 589) from Prairie Mer Rouge,

Louisiana, has a diameter of four inches and a height of two. Like all

the nests of this family, the cavity is very shallow, its deepest

depression being hardly half an inch. So far from corresponding with

the descriptions generally given of it, this nest is well and even

strongly put together, although a portion of the base and some of the

external parts are somewhat openly interwoven, as if for ventilation.

These materials are fragments of plants, catkins, leaves, stems, and

grasses. These seem to constitute a distinct part of the nest, and are

of unequal thicknesses in different parts of the structure. Within

this external frame is a much more artistic and elaborately interwoven

basket, composed entirely of fine, slender, and dry grasses,

homogeneous in character, and evidently gathered just at the time its

seed was ripening. It is of a bright straw-yellow, and forms the whole

internal portion of the nest.

The eggs vary somewhat in size and shape, from an oblong to a rounded

oval. Their length is from .80 of an inch to an inch, and their

breadth averages .68. Their color is a bright light shade of

emerald-green, spotted, marbled, dotted, and blotched with various

shades of lilac, brownish-purple, and dark-brown. These are generally

well diffused equally over the entire egg.

SP. CHAR. Length, 8.60 (fresh specimen); extent, 13.50; wing, 4.24;

tail, 3.68; culmen, .84; tarsus, .80. _Male._ Generally rich pure

vermilion, similar to that of _æstiva_, but lighter, brighter than in

eastern examples, and less rosaceous than in Central American

specimens. Upper surface scarcely darker than lower, the head above

being hardly different from the throat, and abruptly lighter than the

back, which, with the wings and tail, is of a much lighter dusky-red

than in _æstiva_; exposed tips of primaries pure slaty-umber,

primaries faintly margined terminally with paler (in the type, this

character is not apparent, owing to the feathers being somewhat worn;

in other specimens, however, it is quite a noticeable feature,

although possibly not to be entirely relied on). _Female._ Above

orange-olivaceous, beneath more light yellowish, purest medially;

crissum richer yellow than other lower parts, being in some

individuals (young males?) intense Indian-yellow, with the inner webs

of the tail-feathers margined with the same; quite distinct line of

orange-yellow over the lores.

HAB. Upper Rio Grande and Colorado region of Southern Middle Province;

south, in winter, along Pacific coast of Mexico as far as Colima.

This bird, quite different from Eastern _æstiva_, is, however,

probably only a representative form of the same species in the

Colorado and Upper Rio Grande region, migrating south in winter,

through Western Mexico to Colima, as specimens from Texas and Middle

Mexico appear to be quite intermediate, at least in form.

HABITS. This is a new form, whose claim to distinctness was first made

known by Mr. Ridgway, in 1869. In appearance, it most resembles the

_P. æstiva_, but is larger. It has been found in the Middle Province

of the United States, from Fort Mohave at the north, to Colima and

Mazatlan in Mexico.

Dr. Cooper found this bird quite common near Fort Mohave, after April

25, in the Colorado Valley, latitude 35°. They chiefly frequented the

tall cottonwood, feeding on insects, and occasionally flew down to the

_Larrea_ bushes after a kind of bee found on them. He states also that

they have a call-note sounding like the words _ke-dik_, which, in the

language of the Mojave Indians, signifies “come here.” They sing in a

loud, clear tone, and in a style much like that of the Robin, but with

a power of ventriloquism which makes the sound appear much more

distant than it really is. The only specimens of this species known to

have been obtained in the United States were taken at Los Pinos, New

Mexico, by Dr. Coues, and at Fort Mohave by Dr. Cooper. Other

specimens have been procured from Western Mexico.
