Chestnut-crested Cotinga

Large arboreal spinetail restricted to the upper Cotacajes river valley in NW Bolivia, where primarily known from the Inquisivi area in open woodland near treeline. From the similar Ash-browed Spinetail by whitish breast and pale nape. Song a very high, accelerating series of about 20 squeaks given over ~1.5 seconds that drops slightly in pitch over the course of the song.

Not closely related to Northern Mockingbird. Skulking and heard far more often than seen, this fairly large and ample-tailed songbird might be better named "denim catbird" for its overall dull blue plumage, mewing calls, and retiring behavior. Favors thickets, dense scrubby woodlands, and forest understory in foothills and highlands; locally to western lowlands in winter. Tosses leaves on the ground and also feeds at all levels in dense fruiting bushes and trees. Most often seen in short flights across roads or trails from cover to cover. Voice notably varied.

A medium-sized bird of foothill forest midstory. Brown back, pale cinnamon belly, gray head and white throat. Similar to Little Shrikethrush, but Rusty Whistler is smaller and usually has a contrasting white throat. Often found in pairs foraging for insects. A vocal species with a typical whistler array of notes, including various warbles and a ringing, high-pitch note, often followed by a downward “chew chew!” or a sharp upward “wik wik!”.
