Winter habits of Buteo's Archibutus
For the last three weeks the interior of the country both to the North and West has been buried in snow while a narrow strip bordering on the sea coast and extending inland perhaps eight or ten miles has been left nearly bare.
As a consequence several species of birds have flocked into our section in more than ordinary numbers, Hawks especially have soon occurred in remarkable remoter abundance, and I have had a fine opportunity of studying the habits of three of the larger species side by side - namely - B Boralis, B Lunulatus and Archibutus Lagopus. So begin with the Buteo, They are usually given by authors as possessing the same habits, cry, &c but it is not so, at least in my experience, for in all there I found them to differ essentially.
B Boralis is a bird of the open, All day long it sits in an erect position on some the horizontal branch of some detached close in the meadows, or occasionally on the edge of some little oak grove over a springy "mire" on the sheltered side of a hill watching intently the ground beneath - If it perceives a mouse or other small quadruped it slides swiftly downward with half closed wings, then extending its claws and raising its wing, seizes its prey, and either devours it on the spot or moves with it to some distance - Frequently it misses its aim, stands a moment watching, then as it spies its would be victim making off perhaps several yards ahead, runs clumsily with flapping wings in pursuit and easily strikes again, but in this second attempt I have rarely seen it succeed.
