Brewer's Blackbird
Euphagus cyanocephalus
Breeding males are glossy black with purplish head and greenish sheen on body. Nonbreeding males have pale eyebrows and staring yellow eye. Females are plain dark brown and typically have dark eyes. Forages by walking on ground. Sometimes in mixed flocks with other blackbirds at feedlots. Also, walks along parking lots, golf courses, or roadsides. Females similar to Brown-headed Cowbird, but with longer, thinner bill and longer tail than cowbird.
Identification
Adult males have black plumage with an iridescent purple head and neck and glossy bluish-green highlights on the rest of the body. The feet and legs are black and the eye is bright yellow. The female is brownish-grey with slight hints of the male's iridescence. The female's eye is dark brown, while the male's is bright yellow. Overall, they resemble the eastern member of the same genus, the rusty blackbird; Brewer's blackbird, however, has a shorter bill and the male's head is iridescent purple. This bird is often mistaken for the common grackle but has a shorter tail. The call is a sharp check which is also distinguishable. This bird is in a different family from the Eurasian blackbird.

Range and habitat
Their breeding habitat is open and semi-open areas, often near water, across central and western North America. They are also very common in parking lots or around schools, and easily acclimate to the presence of people. They can live in low elevation, as low as below sea level in Southern California, and elevation as high as 8,000 feet. They are capable of surviving in diverse environments, including marshlands and forests. <p>These birds are often permanent residents in the west. Other birds migrate to the Southeastern United States and Mexico in Spring. The range of this bird has been expanding east in the Great Lakes region. They've expanded their habitat as recently as the 20th century.

Behavior
When Brewer's blackbirds identify threats, such as hawks or even humans, they dive towards them and omit an alarm call. Sometimes, when particularly threatened, they will use physical force on predators. <p>Brewer's blackbirds often walk along the ground. They can be seen making jerking motions with their heads. In colder months, these birds tend to flock together and forage. Sometimes, other species of blackbirds will join these flocks. During nesting season, their foraging behavior becomes more independent. Brewer's blackbirds have been seen cleverly following vehicles plowing fields, eating the churned up insects.

Other Birds
Puff-backed Bulbul
Microtarsus eutilotus
Brown bulbul with a sparse, wispy crest. Darker above and paler below. Grayish face, thick black bill, and plain coloration make this a readily identifiable species, albeit an unremarkable one. Gives a sweet, quiet warble: “chee-wee’li’li’wee”. Primarily a lowland species, but ascends into hill forest in some areas. Found in mature forest, forest edges, and tall secondary growth. Often joins other species in mixed flocks, usually at mid-level.
Rock Earthcreeper
Ochetorhynchus andaecola
Common earthcreeper of wooded and shrubby parts of the high Andes and Altiplano from NW Argentina to N Bolivia, including ravines and Polylepis woodland. Despite its name, prefers low vegetation, and is generally absent from open desert areas (where Straight-billed Earthcreeper is more common). From other earthcreepers by thick streaks on belly and rufous tail. Song a series of rising, squeaky nasal “weep!” notes.
Andean Cock-of-the-rock
Rupicola peruvianus
One of the iconic birds of the Andes. Fairly large, significantly larger and chunkier than a thrush. Found in cloud forest at middle elevations, most often at a dawn display site where males make piglike squeals and jump and dance for females. Sometimes seen elsewhere in the forest, especially at fruiting trees. Males can be either brilliant crimson or orange, always with black wings and broad silver tertials, orange legs, and puffy rounded crest. Female duller brown with smaller crest; note staring pale eye. Nests on large rocks or cliff faces. Only similar species is Guianan Cock-of-the-rock, but no range overlap.
