Էջ 67 - Hawk is destructive to poultry, but the writer in all his field experience has never seen one attack, a fowl, nor has he found the remains of one in the stomachs of those examined.
Էջ 162 - Owl is nocturnal in its habits, remaining quiet during the day in the thick foliage of the trees or bushes. In fact, its vision is apparently so affected by bright light that many specimens have been captured alive by persons walking up and taking them in their hands. On this account the Eskimo in Alaska have given it the name of 'blind one.
Էջ 42 - Northwest," p. 338). Dr. BH Warren writes : " Of the thirty-four birds which I have examined, sixteen showed the food taken to have been chickens ; ten revealed small birds — sparrows, warblers, and meadowlarks ; two, quail ; one, bull-frog; three, mice and insects; two, hair and other remains of small quadrupeds " (" Birds of Pennsylvania," 1888, p. 80). Three stomachs examined by the author were all empty, but one bird was shot while killing a chicken. .The Pigeon Hawk (Falco columbarius columbarius)...
Էջ 200 - ... the trouble of digging for themselves. Community of interest makes them gregarious to an extent unusual among rapacious birds; while the exigencies of life on the plains cast their lot with the rodents.

A brant or duck is carried off bodily to the nearest marsh or sandbar. But a Canada goose is too heavy to be thus easily disposed of ; the two great birds fall together to the water beneath, while the eagle literally tows his prize along the surface until the shore is reached. In this way one has been known to drag a large goose for nearly half a mile.
Էջ 30 - In fourteen examinations made by myself, seven hawks had only field mice in their stomachs; three, frogs; two, small birds (warblers) ; one, a few feathers, apparently of a sparrow (Mclospiza), and fragments of insects; one, a large number of grasshoppers, with a small quantity of hair, undoubtedly that of a young rabbit.
Էջ 195 - The hawk owl is strictly diurnal, as much so as any of the hawks, and like some of them often selects a tall stub or dead-topped tree in a comparatively open place for a perch, where it sits in the bright sunlight watching for its prey. Although the flight is swift and hawk-like, it has nevertheless the soft, noiseless character common to the other owls. .When starting from any high place, such as the top of a tree, it usually pitches down nearly to the ground, and flies off rapidly above the tops...
Էջ 31 - The Marsh Hawk is unquestionably one of the most beneficial as it is one of our most abundant Hawks, and its presence and increase should be encouraged in every way possible, not only by protecting it by law, but by disseminating a knowledge of the benefits it confers. It is probably the most active and determined foe of meadow mice and ground squirrels, destroying greater numbers of these pests than any other species, and this fact alone should entitle it to protection, even if it destroyed no other...
Էջ 30 - ... the last-named animals that the writer rarely has examined a stomach from the West which did not contain their remains. In addition to the above it preys upon lizards, frogs, snakes, insects, and birds; of the latter, the smaller grounddwelling species usually are taken.
