_The Goat-sucker, caprimulgus Europeus._—This is the fern owl, nightjar, or night-hawk, a bird, as an English writer has observed, particularly ill-named, its last title only being consistent with its character. When hawking for bats it flies within a few feet of the ground, but when in pursuit of moths it glides round and round the trunk of some tree, the haunt of its prey, with great perseverance. The term goat-sucker is derived from a strange notion very prevalent in olden times that this bird was in the habit of taking the milk of the goat for its own use. Our American night-hawk differs in some particulars from that of Europe. _The Bustard, otis tarda._—This is a large bird of the _cursores_ or running tribe, four feet in length, and nine in breadth, weighing as much as thirty pounds in some instances. The plumage is reddish orange, spotted and barred with black, with the more conspicuous wing and tail feathers, brown and black. Under the neck there is a sort of skin pouch, capable of containing half a gallon. The flesh is much prized. The bustard is now a very rare bird in England, but in France they are less uncommon. They will probably soon become extinct in Great Britain, like the wood-grous, which, within the last eighty years, has disappeared from that country. _The Grous, tetrao._—There were, until recently, three well known species of grous in Great Britain. 1st. The Black Grous or heath cock, a bird of wholly black plumage, found in the heathy districts of the three kingdoms. 2d. The Red Grous, or moor fowl, very abundant in the Scotch moors, and found in no other part of Europe, being the only bird peculiar to Britain. 3d. The Wood-Grous, formerly by no means uncommon, but which has recently become quite extinct in Great Britain, although it is still found on the continent of Europe. _The Titmouse, parus._—The titmice are dispersed more or less over the whole world, excepting some portions of the southern hemisphere, as South America, and New Holland. In England, they have seven or eight different species: the great tit, _p. major_; colemouse, _p. ater_; marshtit, _p. palustris_; long-tailed tit, _p. caudatus_; blue tit, _p. cæruleus_; bearded tit, _p. biarmicus_; crested tit, _p. cristatus_. In the United States, we have three species: the common chicadee, _p. atricapillus_; the caroline titmouse, _p. carolinensis_; and the crested titmouse, _p. bicolor_. This last is found in Europe also, but in England it is very rare. All three species belong to the birds of New York.
