Crissal Thrasher
Toxostoma crissale
Dark grayish thrasher with distinctive rufous undertail coverts. Bill long and strongly curved. Tail long and dark. Obvious dark line separating white mustache and white throat. Yellow eye. Secretive and uncommon, although perches conspicuously when singing. Found in brushy deserts. With a good view, easily distinguished from more common Curve-billed Thrasher by darker gray color and rufous undertail coverts. Listen for jumbled, rambling song.
识别特征
The bird grows to 32 centimetres (13 in), and has a deeply curved bill. The eyes are dull yellow. Bird expert Roger Tory Peterson described its singing as sweeter and less spasmodic than other thrashers. It can be found near desert streams in dense underbrush, mesquite thickets, willows, scrub oak, high elevations in manzanita, and in the low desert near canyon chaparral. The bird seldom flies in the open. As such, the crissal thrasher rarely flies, preferring to walk or run around its territory and will mostly run for cover when disturbed by a potential predator. The bird's name is derived from the characteristic bright coloring, in contrast to the balance of its plumage, of the area between its tail and vent—a region known as the crissum.

Yellow-throated Fiji Whistler
Pachycephala graeffii
A brightly colored songbird with a bright golden belly and throat, a black hood and chest band, and an olive upperside and wings. Female is dull overall, with brown upperparts, pale belly, off-white throat, and no breast band. Endemic to northern and western Fiji, where mostly inhabits mature forest, but also secondary growth. Song consists of a melodic whistled series, typically concluded with a decisive-sounding “whit!” note. Formerly treated as part of more broadly-defined “Fiji Whistler” alongside White-throated Fiji Whistler.

Williams's Lark
Mirafra williamsi
A small, compact lark with variable dark- to rusty-brown upperparts, sometimes with darker streaks or feather centers, pale eyebrows and throat, and a pale belly that contrasts with the heavily streaked chest, often washed rufous. The tail is brownish with white outer feathers that are conspicuous in flight. Restricted to a very specific habitat, rocky lava-strewn plains in semi-desert, in two areas of Kenya. Vocalizations are poorly known, but a loud “tsireet” has been recorded during the display flight. Other similar larks are generally less rusty and less streaked on the chest.

Summer Tanager
Piranga rubra
Large tanager with a hefty bill. Adult males are completely red; immature males are dull yellow-olive with blotchy patches of red. Females are variable in color, ranging from pale dull yellow to brighter orange. Can be confused with female Scarlet Tanager; Summer has a longer, paler bill and less contrast between wing and body color. Also compare with dustier-looking, stouter-billed Hepatic Tanager. Breeds in mature forests, favoring mixed deciduous and pine in the southeastern U.S. and riparian corridors in the western U.S. and northern Mexico. Extensive winter range from Mexico to Bolivia, where it can be found in any wooded area. Often gives a short, descending rattle “pit-a-tuck.”
