The food of the Mocking-Bird is chiefly insects, their larvæ, worms, spiders, etc., and in the winter of berries, in great variety. They are said to be very fond of the grape, and to be very destructive to this fruit. Mr. G. C. Taylor (Ibis, 1862, p. 130) mentions an instance that came to his knowledge, of a person living near St. Augustine, Florida, who shot no less than eleven hundred Mocking-Birds in a single season, and buried them at the roots of his grape-vines.
Several successful attempts have been made to induce the Mocking-Bird to rear their young in a state of confinement, and it has been shown to be, by proper management, perfectly practicable.
In Texas and Florida the Mocking-Bird nests early in March, young birds appearing early in April. In Georgia and the Carolinas they are two weeks later. In Pennsylvania they nest about the 10th of May, and in New York and New England not until the second week of June. They select various situations for the nest; solitary thorn-bushes, an almost impenetrable thicket of brambles, an orange-tree, or a holly-bush appear to be favorite localities. They often build near the farm-houses, and the nest is rarely more than seven feet from the ground. The base of the nest is usually a rudely constructed platform of coarse sticks, often armed with formidable thorns surrounding the nest with a barricade. The height is usually 5 inches, with a diameter of 8. The cavity is 3 inches deep and 5 wide. Within the external barricade is an inner nest constructed of soft fine roots.
The eggs, from four to six in number, vary in length from .94 to 1.06 inches, with a mean length of .99. Their breadth varies from .81 to .69 of an inch, mean breadth .75. They also exhibit great variations in the combinations of markings and tints. The ground color is usually light greenish-blue, varying in the depth of its shade from a very light tint to a distinct blue, with a slight greenish tinge. The markings consist of yellowish-brown and purple, chocolate-brown, russet, and a very dark brown.
Galeoscoptes, Cabanis, Mus. Hein. I, 1850, 82. (Type Muscicapa carolinensis, L.)
Gen. Char. Bill shorter than the head, rather broad at base. Rictal bristles moderately developed, reaching to the nostrils. Wings a little shorter than the tail, rounded; secondaries well developed; fourth and fifth quills longest; third and sixth little shorter; first and ninth about equal, and about the length of secondaries; first quill more than half the second, about half the third. Tail graduated; lateral feather about .70 shorter than the middle. Tarsi longer than middle toe and claw by about an additional half-claw; scutellate anteriorly, more or less distinctly in different specimens; scutellæ about seven.
The conspicuous naked membranous border round the eye of some Thrushes, with the bare space behind it, not appreciable.

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 СКАЧАТЬ
