There is little difference in form between the single species of Galeoscoptes and Mimus polyglottus, beyond the less degree of definition of the tarsal plates; and but for the difference in coloration (uniform plumbeous instead of gray above and white beneath), we would hardly be inclined to distinguish the two generically.
The single species known is lead-colored, with black cap, and chestnut-red under tail-coverts.

Western specimens have not appreciably longer tails than Eastern. Central American examples, as a rule, have the plumbeous of a more bluish cast than is usually seen in North American skins.
Habits. The Catbird has a very extended geographical range. It is abundant throughout the Atlantic States, from Florida to Maine; in the central portion of the continent it is found as far north as Lake Winnepeg.
On the Pacific coast it has been met with at Panama, and also on the Columbia River. It is occasional in Cuba and the Bahamas, and in the Bermudas is a permanent resident. It is also found during the winter months abundant in Central America, It breeds in all the Southern States with possibly the exception of Florida. In Maine, according to Professor Verrill, it is as common as in Massachusetts, arriving in the former place about the 20th of May, about a week later than in the vicinity of Boston, and beginning to deposit its eggs early in June. Near Calais it is a less common visitant.
The Northern migrations of the Catbird commence early in February, when they make their appearance in Florida, Georgia, and the Carolinas. In April they reach Virginia and Pennsylvania, and New England from the 1st to the 10th of May. Their first appearance is usually coincident with the blossoming of the pear-trees. It is not generally a popular or welcome visitant, a prejudice more or less wide spread existing in regard to it. Yet few birds more deserve kindness at our hands, or will better repay it. From its first appearance among us, almost to the time of departure in early fall, the air is vocal with the quaint but attractive melody, rendered all the more interesting from the natural song being often blended with notes imperfectly mimicked from the songs of other birds. The song, whether natural or imitative, is always varied, attractive, and beautiful.
The Catbird, when once established as a welcome guest, soon makes itself perfectly at home. He is to be seen at all times, and is almost ever in motion. They become quite tame, and the male bird will frequently apparently delight to sing in the immediate presence of man. Occasionally they will build their nest in close proximity to a house, and appear unmindful of the presence of the members of the family.
The Catbird’s power of mimicry, though limited and imperfectly exercised, is frequently very amusing. The more difficult notes it rarely attempts to copy, and signally fails whenever it does so. The whistle of the Quail, the cluck of a hen calling her brood, the answer of the young chicks, the note of the Pewit Flycatcher, and the refrain of Towhee, the Catbird will imitate with so much exactness as not to be distinguished from the original.
The Catbirds are devoted parents, sitting upon their eggs with great closeness, feeding the young with assiduity, and accompanying them with parental interest when they leave the nest, even long after they are able to provide for themselves. Intruders from whom danger is apprehended they will boldly attack, attempting to drive away snakes, cats, dogs, and sometimes even man. If these fail they resort to piteous cries and other manifestations of their great distress.
Towards each other they are affectionate and devoted, mutually assisting in the construction of the nest; and as incubation progresses the female, who rarely leaves the nest, is supplied with food, and entertained from his exhaustless vocabulary of song, by her mate. When annoyed by an intruder the cry of the Catbird is loud, harsh, and unpleasant, and is supposed to resemble the outcry of a cat, and to this it owes its name. This note it reiterates at the approach of any object of its dislike or fear.
The food of the Catbird is almost exclusively the larvæ of the larger insects. For these it searches both among the branches and the fallen leaves, as well as the furrows of newly ploughed fields and cultivated gardens. The benefit it thus confers upon the farmer and the horticulturist is very great, and can hardly be overestimated.
The Catbird can with proper painstaking be raised from the nest, and when this is successfully accomplished they become perfectly domesticated, and are very amusing pets.
They construct their nests on clusters of vines or low bushes, on the edges of small thickets, and in retired places, though almost always near cultivated ground. The usual materials of their nests are dry leaves for the base, slender strips of long dry bark, small twigs, herbaceous plants, fine roots, and finer stems. They are lined with fine dry grasses, and sedges. Their nests average 4 inches in height by 5 in diameter. The diameter and depth of the cavity are 3½ inches. The eggs are of a uniform deep bluish-green, and measure .97 in length and .69 of an inch in breadth.
Family CINCLIDÆ.—The Dippers
On page 2 will be found the characteristics of this family, which need not be here repeated. There is only a single genus, Cinclus, with four American species, and several from Europe and Asia.

Cinclus mexicanus.
8117
Gen. Char. Bill without any bristles at the base; slender, subulate; the mandible bent slightly upward; the culmen slightly concave to near the tip, which is much curved and notched; the commissural edges of the bill finely nicked towards end. Feet large and strong, the toes projecting considerably beyond the tail; the claws large. Lateral toes equal. Tail very short and even; not two thirds the wings, which are concave and somewhat falcate. The first primary is more than one fourth the longest. Eggs white.
Cinclus mexicanus.
The slightly upward bend of the bill, somewhat as in Anthus, renders the culmen concave, and the commissure slightly convex. The maxilla at base is nearly as high as the mandible; the whole bill is much compressed and attenuated. The lateral claws barely reach the base of the middle one, which is broad; the inner face extended into a horny lamina, with one or two notches or pectinations somewhat as in Caprimulgidæ. The stiffened sub-falcate wings are quite remarkable. The tail is so short that the upper coverts extend nearly to its tip.
The species are all dull-colored birds, usually brown, sometimes varied with white on the head, back, or throat. They inhabit mountainous subalpine regions abounding in rapid streams, and always attract attention by their habit of feeding under water, searching among the gravel and stones for their insect prey.
The only other species at all allied to the single North American one are the C. ardesiacus of Central America, and C. pallasi of Eastern Asia. They may be easily distinguished by the following characters:—
Plumage beneath scarcely lighter than that above; head and neck brownish, darkest above. Wing, 4.00; tail, 2.15; bill, .50; tarsus, 1.20; middle toe, .85. Legs (in life), pinkish white (8,496 Fort Mass. N. M.). Hab. Mountains of Middle Province from Sitka, south to Guatemala … var. mexicanus.
Plumage beneath much lighter than that above,—very light along the median line; head not brownish, the contrast in shade between upper and lower surfaces very marked. Wing, 3.50; tail, 2.05; bill, .45; tarsus, 1.30; middle toe, .90. Legs yellow. (42,788 ♂ Costa Rica). Hab. Guatemala and Costa Rica … var. ardesiacus.24
Plumage uniform dusky-brown, middle of belly blackish; back and rump squamated with black; wings and tail blackish-brown. Total length, 8.00; wing, 4.00; tail, 2.50; tarsus, 1.25; bill (to rictus), 1.10 (Salvin). Hab. Lake Baikal to Kamtschatka; Amoorland; S. E. Siberia; Japan (Salvin) … var. pallasi.25

Sp. Ch. Above dark plumbeous, beneath paler; head and neck all round a shade of clove or perhaps a light sooty-brown; less conspicuous beneath. A concealed spot of white above the anterior corner of the eye and indications of the same sometimes on the lower eyelid. Immature specimens usually with the feathers beneath edged with grayish-white; the greater and middle wing-coverts and lesser quills tipped with the same. The colors more uniform. Length, 7.50; wing, 4.00; tail, 2.55.
Young. Similar to the adult, but much mixed with whitish medially beneath; this in form of longitudinal suffusions.
Autumnal and winter specimens have numerous transverse crescents of whitish on lower parts and wings,—these very especially conspicuous posteriorly; the secondaries are also conspicuously terminated with a white crescent. Bill brown, paler toward base of lower mandible. In spring and summer the bill entirely black, and the whitish markings almost entirely disappear; the young bird has a greater amount of white beneath than the adult in winter dress, and this white is disposed in longitudinal, not transverse, suffusions. The color of the legs appears to be the same at all seasons.

Specimens, of any age, from the coast of Oregon and the Cascade Mountains, have the head more deeply brownish than those from other regions.
Hab. Found through the mountainous region of the central and western part of North America, from Fort Halkett south into Mexico and Guatemala. Orizaba (Alpine region) Sumich. None received from the coast region of California. Abundant on the N. W. coast, Laramie Peak and Deer Creek, Neb.
This species has a wide range along the mountainous region of North and Middle America. Mexican specimens are darker.
Habits. This interesting bird inhabits exclusively the mountainous portions of North America west of the Mississippi from Alaska south to Guatemala. It does not appear to have been obtained on the coast of California, nor in the valley of the Mississippi. In the British Possessions specimens have been procured on Fraser’s River, at Fort Halkett, and at Colville. At the latter place Mr. J. K. Lord states that a few remain and pass the winter. They are found among the mountain streams of Vera Cruz, and probably throughout Mexico, and no doubt may be met with in all the highlands between these extreme points. Dr. Newberry met with it in the rapid streams of the Cascade Mountains. He describes it as flitting along in the bed of the stream, from time to time plunging into the water and disappearing, to appear again at a distant point, up or down the stream, skipping about from stone to stone, constantly in motion, jerking its tail and moving its body somewhat in the manner of a wren.
Dr. Cooper observed this species both on the Columbia and its tributaries, and also among the mountain streams of the Coast Range west of Santa Clara. At the latter place he found a pair mated as early as March 16th. At sunset he heard the male singing very melodiously, as it sat on one of its favorite rocks in the middle of the foaming rapids, making its delightful melody heard for quite a long distance above the sound of the roaring waters.
“This bird,” adds Dr. Cooper, “combines the form of a sandpiper, the song of a canary, and the aquatic habits of a duck. Its food consists almost entirely of aquatic insects, and these it pursues under water, walking and flying with perfect ease beneath a depth of several feet of water.” He also states that they do not swim on the surface, but dive, and sometimes fly across streams beneath the surface; that their flight is rapid and direct, like that of a sandpiper; also that they jerk their tails in a similar manner, and generally alight on a rock or log.
Dr. Cooper on the 5th of July found a nest of this bird at a saw-mill on the Chehalis River, built under the shelving roots of an enormous arbor-vitæ that had floated over, and rested in a slanting position against the dam. The floor was of small twigs, the sides and roof arched over it like an oven, and formed of moss, projecting so as to protect and shelter the opening, which was large enough to admit the hand. Within this nest was a brood of half-fledged young. The parents were familiar and fearless, and had become accustomed to the society of the millers. They had previously raised another brood that season.
The same observant naturalist, some time afterwards, in May, found the nest of another pair, a few miles north of Santa Clara. This was built near the foot of a mill-dam, resting on a slight ledge under an overhanging rock, from which water was continually dropping. It was, in shape, like an oven, with a small doorway, and it was built externally of green moss, which, being still living, prevented the easy discovery of the nest. It was lined with soft grass, and contained young.
These birds are found singly or in pairs, and never more than two together. They are never found near still water, and frequent only wild mountain-streams, cascades, eddies, and swift currents.
According to Mr. Dall’s observations in Alaska, the species is essentially solitary. He obtained several specimens in January, February, and March, always near some open, unfrozen spots in the Nulato River. It was only found in the most retired spots, and almost invariably alone. When disturbed, it would dive into the water, even in midwinter.
Mr. Ridgway describes the Dipper as remarkably quick, as well as odd, in its movements,—whether walking in the shallow bed of the stream, or standing on a stone along the edge, continually tilting up and down, now chattering as it flies rapidly along the stream, again alighting into the water, in which it wades with the greatest facility. Its flight is remarkably swift and well sustained, and in manner is very unusual, the bird propelling itself by a rapid buzzing of the wings, following in its flight every undulation in the course of the stream into which it drops suddenly. Its song is described as remarkably sweet and lively, in modulation resembling somewhat that of the Harporhynchus rufus, but less powerful, though sweeter in effect.
Dr. E. Baldamus, of Halle, who possesses specimens of the eggs of this species, describes them as pure white in color, oval in shape, and hardly distinguishable from those of the European C. aquaticus.
A nest of this bird obtained by Mr. J. Stevenson, of Hayden’s Expedition, in Berthoud’s Pass, Colorado, is a hemisphere of very uniform contour built on a rock, on the edge of a stream. Externally it was composed of green moss, in a living state; within is a strong, compactly built apartment, arched over, and supported by twigs, with a cup-like depression at the bottom, hemispherical and composed of roots and twigs firmly bound together. The structure is 7 inches in height externally, and has a diameter of 10½ inches at the base. Within, the cavity has a depth of 6 inches; the entrance, which is on one side, is 3½ in breadth by 2½ in height. The eggs were three in number, uniform, dull white, and unspotted. They measure 1.04 inches by .70. They have an elongated oval shape, and are much pointed at one end.
Family SAXICOLIDÆ.—The Saxicolas
The general characters of this family have already been given on p. 2, as distinguished from the Turdidæ. The relationships are very close, however, and but little violence would be done by making it a subfamily of Turdidæ or even a group of Turdinæ, as was done in the “Birds of North America.”
While the group is very well represented in the Old World, America has but one peculiar genus Sialia, and another Saxicola, represented by a single species, a straggler, perhaps, from Greenland on the one side and Siberia on the other. The diagnostic characters of these are as follows, including Turdus to show the relationships of the three genera:—
Turdus. Tarsi long, exceeding the middle toe; wings reaching to the middle of the tail, which is about four fifths the length of the wings. Bill stout; its upper outline convex toward the base. Second quill shorter than fifth.
Saxicola. Tarsi considerably longer than the middle toe, which reaches nearly to the tip of the tail. Tail short, even; two thirds as long as the lengthened wings, which reach beyond the middle of the tail. Second quill longer than fifth. Bill attenuated; its upper outline concave towards the base.
Sialia. Tarsi short; about equal to the middle toe. Wings reaching beyond the middle of the tail. Bill thickened.
Genus SAXICOLA, Bechstein

Gen. Char. Commissure slightly curved to the well-notched tip. Culmen concave for the basal half, then gently decurving. Gonys straight. Bill slender, attenuated; more than half the length of head. Tail short, broad, even. Legs considerably longer than the head; when outstretched reaching nearly to the tip of tail. Third quill longest; second but little shorter. Claws long, slightly curved; hind toe rather elongated.
As already stated, America possesses but a single member of this group of birds, so well represented in the Old World. The color is bluish-gray, with wings, a stripe through the eye, and the middle of exposed tail-feathers black.

Saxicola œnanthoides, Vigors, Zoöl. Blossom, 1839, 19 (N. W. America).—Cassin, Ill. I, 1854, 208, pl. xxxiv (Nova Scotia).
Sp. Char. (Description from European specimen.) Male in spring, forehead, line over the eye, and under parts generally white; the latter tinged with pale yellowish-brown, especially on the breast and throat. A stripe from the bill through, below, and behind the eye, with the wings, upper tail-coverts, bill and feet, black. Tail white, with an abrupt band of black (about .60 of an inch long) at the end, this color extending further up on the middle feather. Rest of upper parts ash-gray; quills and greater coverts slightly edged with whitish. Length, 6.00; wing, 3.45; tail, 2.50; tarsus, 1.05.
Autumnal males are tinged with rusty; the black markings brown. The female in spring is reddish-gray; lores and cheeks brown; the black markings generally brownish, and not well defined. Eggs pale light blue. Nest on ground.
Hab. An Old World species (Europe, Northern Africa, and Asia), abundant in Greenland, found probably as an autumnal migrant in Labrador, Canada, Nova Scotia, Bermuda, etc. Occurs also on Norton Sound, near Behring’s Straits. Very occasional in the Eastern States: Long Island.
Saxicola œnanthe.
This bird appears to be abundant in Norton Sound, from which region Mr. Dall has recently brought specimens in full spring plumage. These are decidedly smaller than birds from Labrador and Greenland, but not distinguishable, and seem to agree precisely with skins from Central Europe.
Habits. The well-known Wheat-ear is entitled to a place in our fauna, not only as an accidental visitor, but also as an occasional resident. Dr. H. R. Storer, of Boston, found them breeding in Labrador in the summer of 1848, and procured specimens of the young birds which were fully identified by Dr. Samuel Cabot as belonging to this species. In the following year Andrew Downs, of Halifax, gave me the specimen described and figured by Mr. Cassin. This was secured late in the summer near Cape Harrison, Labrador, where it had evidently just reared its brood. In 1860 Mr. Elliott Coues obtained another specimen on the 25th of August, at Henley Harbor. It was in company with two others, and was in immature plumage. Its occurrence in considerable numbers on the coast of Labrador is further confirmed by a writer (“W. C.”) in “The Field,” for June 10, 1871, who states that when in that region during the months of May and June he saw a number of “White Ears,” the greater proportion of them being males. He inferred from this that they breed in that country, the apparent scarcity of females being due to their occupation in nesting. Mr. Lawrence has one in his cabinet from Long Island, and the Smithsonian Institution one from Quebec. Specimens have also been obtained in the Bermudas.
Holböll, in his paper on the fauna of Greenland, is of the opinion that the individuals of this species that occur there come from Europe, make their journey across the Atlantic without touching at Iceland, and arrive in South Greenland as early in the season as it does at the former place, the first of May. It reaches Godhaven a month later, at times when all is snowbound and the warmth has not yet released the insects on which it feeds. It is found as far north as the 73d parallel, and even beyond. In September it puts on its winter dress and departs.
Mr. Dall states that several large flocks of this species were seen at Nulato, May 23 and 24, 1868, and a number of specimens obtained. They were said to be abundant on the dry stony hill-tops, but were rare along the river.
The Wheat-ear is one of the most common birds of Europe, and is found, at different seasons, throughout that continent as well as in a large portion of Western Asia. It breeds throughout the British Islands as well as in the whole of Northern Europe and Asia.
Its food is principally worms and insects, the latter of which it takes upon the wing, in the manner of a fly-catcher. The male bird is said to sing prettily, but not loudly, warbling even when on the wing, and hovering over its nest or over its partner. In confinement its song is continued by night as well as by day.
The Wheat-ear begins to make its nest in April, usually concealing it in some deep recess beneath a huge stone, and often far beyond the reach of the arm. Sometimes it is placed in old walls, and is usually large and rudely constructed, made of dried bents, scraps of shreds, feathers, and rubbish collected about the huts, generally containing four pale blue eggs, uniform in color, and without spots, which measure .81 of an inch in length by .69 in breadth.

Habits. The Bluebird is abundant throughout the eastern portion of North America, breeding in nearly every part, from Georgia and Louisiana to the Arctic regions, with only this exception, that near the seaboard its migrations do not extend so far to the north as in the interior. It is very rarely to be met with beyond the Penobscot, although Professor Verrill mentions it as very common in the western part of Maine. It is found throughout the year in the Bermudas, and occasionally in Cuba. The Selkirk Settlement is the most northern locality to which it has been traced. It is not known to occur farther west than the highlands west of the Mississippi.
Through all the Eastern States the Bluebird is one of the most familiar and welcome of the earliest visitors of spring, usually making its appearance as early as the first of March. In mild seasons they come in the latter part of February, long before there is any apparent relaxation of the severity of winter. In 1857, in consequence of the unusual mildness of the season, Bluebirds appeared in large numbers as early as the 15th of February, and remained apparently without suffering any inconvenience, although the weather subsequently became quite severe. In 1869 their first appearance was observed as early as the 28th of January, the earliest period of which I can find any record.
