Western Wood-Pewee

Contopus sordidulus

Drab grayish-brown flycatcher found in deciduous and mixed forests and edges. Nondescript overall with two pale wingbars; bill is usually mostly dark with only limited orange at the base. Note very long wings and larger size than Empidonax flycatchers. Typically seen on a high perch, occasionally sallying out to snatch an insect. Essentially identical to Eastern Wood-Pewee; averages darker overall with weaker upper wingbar, but reliably distinguished only by voice. Listen for buzzy tones, especially the “BREeerr” song.

分布与栖息地

Their breeding habitat is open wooded areas in western North America. These birds migrate to South America at the end of summer. The female lays two or three eggs in an open cup nest on a horizontal tree branch or within a tree cavity; California black oak forests are examples of suitable nesting habitat for this species of bird. Both parents feed the young.

Olive Bushshrike

Olive Bushshrike

Chlorophoneus olivaceus

A bushshrike that has two color morphs: an easily identified “buff morph” that has a pink-fawn chest and throat, and an “olive morph” that has an olive crown and yellow-orange underparts. Females are duller than males, with less distinct facial masks. Singles and pairs often join mixed-species flocks in coastal and montane forest, thickets, and dense woodland. The species hops and creeps stealthily in the canopy and mid-canopy, foraging for insects and fruit. It typically sings a distinctive series of 10 to 15 short musical notes, and also gives a strident alarm call and metallic croaking notes.

Rusty-crowned Babbler

Rusty-crowned Babbler

Sterrhoptilus capitalis

A fairly small bird of lowland and foothill forest and edge, with a rufous crown and a gray back and cheek, all with whitish streaks. Also has dark wings and tail with white outer tail feathers, and off-white underparts blending to a pale orange throat. Note the slender black bill. Often joins mixed-species flocks and sometimes hangs upside down while feeding. Somewhat similar to Brown Tit-Babbler, but slightly larger, with a rufous crown and a white belly. Flocks give a jumble of squeaky chattering notes.

Brewer's Sparrow

Brewer's Sparrow

Spizella breweri

Small, drab sparrow of scrubby areas in western North America, from Alaska to Mexico. Slender and long-tailed, similar in shape and size to Chipping and Clay-colored Sparrows. Note the pale gray nape, pale lores, and plain facial pattern. Breeds mostly in sagebrush; winters in loose flocks in any brushy or grassy area, often with other sparrows. Song is a long series of buzzy, reedy notes mixed with trills; tones and long duration of song are unique.
