Western Screech-Owl
Megascops kennicottii
Pint-sized, cryptically patterned gray owl with fine streaks of black and white; short ear tufts. Found in a variety of wooded habitats, but favors riparian and deciduous areas. Can be found in urban areas and parks. Feeds mostly on small mammals, birds, and insects. Nests in cavities. Listen for its voice at night: a series of short whistled notes that accelerates at the end. Unlike counterpart, Eastern Screech-Owl, they do not have a rufous color morph, only gray morph.
识别特征
Length averages 22 cm (8.7 in), wingspan 55 cm (22 in), and weight 143 g (5.0 oz). Weight ranges from 88 to 220 g (3.1 to 7.8 oz). Females are larger than males and northern populations are notably larger than southern populations. Adults are larger than whiskered screech owls, with larger feet and a more streaked plumage pattern.<p>There are several morphs: brown Pacific, grey Pacific, Great Plains, Mojave, and Mexican. All have either brown or dark gray plumage with streaking on the underparts. There is no red morph. This brown and gray streaky coloring allows the owl to camouflage with trees and hide from predators.<p>They have a round head with ear tufts, yellow eyes, and a yellowish bill. Their appearance is quite similar to whiskered and eastern screech owls, so it is best to identify them by their calls. They were previously considered to be the same species as the eastern screech owl.

Tataupa Tinamou
Crypturellus tataupa
Small tinamou with a red bill, purplish legs, purple back, gray head, and a black-and-white vent. Similar to Small-billed Tinamou, but the song starts with a fast trill “trri trri trri” and ends with a loud descending “trru trru trru.” Prefers moist forests including second growth and dense forest edges.
Gray Falcon
Falco hypoleucos
Seldom-seen pale gray falcon of inland Australia found in arid grassland and woodland habitats, where it sometimes perches high on communication towers. Pale gray upperparts and white underparts, with faint dark streaks below. Legs fully feathered (unlike the long, bare legs of Brown Falcon). In flight, outer upperwing (“hand”) is noticeably darker than the inner wing and back. Wings not as pointed as hobby or Peregrine Falcon. Pale inland Brown Falcons are often misidentified as this species: note that Gray Falcon is unlikely to be seen perched in low bushes or feeding from the ground.
Sykes's Warbler
Iduna rama
Plain brown warbler with pale legs. Breeds in Central Asia; winters primarily on the Indian peninsula. Prefers trees with sparse canopy in open, dry habitat. Can be told from Blyth’s Reed Warbler by its leaf-warbler-like behavior and longer tail, and from Booted Warbler by its less compact appearance; flatter stance; longer pale bill (mostly without a dark tip); longer, more loosely attached tail; more pointy face; harder call; and preference for canopy tops. Call is a hard, fast, continuous arrhythmic “thk…thk, thk, thk.”
