Speckle-fronted Weaver

Extremely similar to widespread Rufous Hummingbird; identical in plumage except for males' solid green back (which can be shown by Rufous too). Breeds only along a narrow strip of coastal California and southern Oregon. On females and immature males, the only way to separate them from Rufous is by the shape of the tail feathers, which is extremely difficult to determine without good photographs.

Small earthcreeper with long tail and curved bill. Inhabits the ground and low vegetation in dense Chaco spiny woodlands and shrubby slopes, where it generally forages alone. Both sexes have uniform orangish-brown plumage. Note the white throat and the dark supercilium. Feeds on small insects and caterpillars gleaned out of the ground. Voice is a series of 5–10 loud notes increasing in volume.

Slender, long-tailed thrush of humid evergreen forest in foothills and highlands. Best known for is ethereal, fluty song; thus, sadly, often sought for the cage bird trade. Usually seen singly, perched quietly and rather upright at low to high levels in forest, but a few may gather at fruiting trees with other species. Plumage slaty gray overall. Broken white eyering is thicker than Brown-backed Solitaire, which is more often a bird of pine-oak forest.
