West Mexican Chachalaca

Small dainty gull. Dark-eyed and long-winged with a rounded head. Breeding adults are white-headed with an unmarked bill; non-breeding adults are smudged on the head and bill. Younger birds are brownish, with black-tipped pink bills. Occurs in western North America, primarily breeding in Alaska and Canada and wintering to Baja. Breeds in wetlands, meadows, and beaches; winters in waterside habitats and fields. Does not frequent large urban centers as much as some other gulls.

A typical black, white, and dark-gray batis. Note the chest band, which is black in males and chestnut in females. Found in woodland and moist savanna, often in pairs. Very similar to Gray-headed Batis, and best distinguished by voice, but also usually shows a darker gray crown. Also similar to Senegal and Pale Batises, but has a narrower white eyebrow stripe than the former and is darker overall than the latter. The distinctive song is a series of hollow whistles on the same pitch. 

Medium-sized, rather slender owl with long "ear" tufts. Extensive range across Northern Hemisphere. North American birds are rather dark and coarsely marked, with pumpkin-colored face patches and yellow eyes. Eurasian populations are paler overall, especially on the face, and have reddish eyes. Strictly nocturnal; rarely seen foraging at dusk and dawn. Found in areas with a mix of dense cover for roosting, such as brushy thickets or conifer groves, and open spaces for hunting. Generally uncommon to rare and seldom-seen, but can gather in communal winter roosts with dozens of individuals (if you're lucky enough to find a roost, do not disturb the birds). Compare with Short-eared Owl. Typical vocalization is a single low “woop” repeated every few seconds; also gives a wide range of maniacal catlike screeches and doglike barks.
