Chestnut-backed Sparrow-Lark

One of the most common and widespread sparrows in North America. Fairly large with a long, rounded tail. Overall coarsely patterned with gray and brown, usually with more reddish-brown wings and tail. Look especially for thick brown streaks on the underparts and a broad dark mustache stripe. Significant variation in plumage geographically: relatively pale and rusty in the southwestern U.S.; blacker streaking in California; overall dusky in the Pacific Northwest. Larger, longer-tailed and usually more rusty than Savannah Sparrow. Found in a variety of scrubby habitats both near and far from human development, especially edges of fields, often near water. Listen for husky "chimp" calls and melodic song with chips and trills.

Chunky finch-like tanager of high elevations. Males are yellow with a gray head, wings, and tail; females are similar but duller. Found in a variety of dry, open habitats including scrub, agricultural areas, and Polylepis woodlands. Often forages in groups on the ground, and may associate with other sierra-finches and similar species. Distinctive within its range; replaced by the similar Black-hooded Sierra-Finch farther south.

Stunning hummingbird with a short straight bill. Males have a dark blue crown with red, blue, and gold tufted “horns” on the side. Otherwise largely metallic green above and white below with a black throat. Females have a green cap and lack the horns. Found in riverine belts and open savanna grasslands; may venture into adjacent human-modified habitats.
