181 I. FIRST ORDER. Rapaces. The first order of birds in the table is represented by two families, Day-Rapaees and Nights Rapaces. The day-rapaces form two tribes : the first—vultures, is repre- sented by only a single species. In the second—falcons—there are four genera of fourteen speeies. The following are the names of aU the species in the first family :— The Turkey-Vulture—Cathartes Aura. The Golden Eagle—Aquila Chrysaetot. The Bald Eagle—Aquila Leucocephela. The Osprey Eagle—Aquila Haliœeta. The Peregrine Falcon—Falco Peregrinus. The Gyr-Falcon—Falco Islandicus. The Little Rusty-crowned Falcon—Falco Sparveriut. The Pigeon-Hawk—Falco Columbarius. The Merlin—Falco ^Esalon. The Goshawk—Accipiter Palumbarius. The Slate-colored Hawk—Accipiter Pennsylvanicus. The Common Buzzard—Buteo Vulgaris. The Red-tailed Buzzard—Buteo Borealis. The Rough-legged Falcon—Buteo Lagopus. The American Hen-Harrier—Buteo Cyaneus.
