Copper Sunbird

Small, distinctive falcon of the Chaco from central Argentina to SE Bolivia and W Paraguay, often seen on tall, exposed perches. Small size and bold white supercilium and malar distinctive. Generally uncommon and in low density throughout range. Call distinctive for a raptor: a slightly warbled, full “skyoot” note given repeatedly.

Small, yellowish-olive flycatcher that ranges mainly in northern and eastern South America as well eastern Panama. Distinguishing features include its yellow throat and breast, orange face, thick wingbars, and wide bill. Similar to Olive-faced Flycatcher, which used to be considered the same species and called Yellow-breasted Flycatcher. Note their different ranges, which mostly do not overlap. Ochre-lored Flycatcher has a brighter face with a hint of orange, more distinct wingbars, and has a different voice. Its most common call is a piercing whistle given alone or in a slow series. Occasionally also gives well-spaced rasping calls. Inhabits secondary forest and light woodland, usually avoiding the interior of mature forest.

An uncommon migrant songbird through Taiwan, rarely encountered anywhere away from breeding grounds on Izu and Tokara Islands, Japan. Olive above and whitish below; best distinguished from similar species by narrow bill with yellowish lower mandible, brownish-pink legs, and weak head pattern. Prefers mature coastal broadleaf forests but uses bamboo patches and conifers during migration as well. Smaller than Eastern Crowned Leaf Warbler, with thinner bill and no crown stripe. Song consists of a series of trills; calls, given often, include a descending “twee” or quiet “pee.”
