Buff-throated Foliage-gleaner (Automolus ochrolaemus) [map] [media] [my records] is split into two species, a bird of the same name that mostly occurs on the Atlantic (Caribbean) slope of Central America to eastern Panama and South America, and the newly described Chiriqui Foliage-gleaner (Automolus exsertus) [map] [media] [my records] endemic to southern Costa Rica and western Panama.

As opposed to genus Dryobates, the three species of Picoides obtain most (some 85%) of their insect prey by pecking live or dead wood. We do this update once each year, taking into account the past 12 months worth of recent taxonomic knowledge on splits, lumps, name changes, and changes in the sequence of the species lists. The males of all three species have yellow on the crown, though this feature is also present in some other pied woodpeckers, namely brown-fronted and yellow-crowned. across western Canada, Alaska and the midwestern United States, and across northern Eurasia from Norway to Korea.

Ecology 64(6), 1437-1443. Its small size makes it versatile, and it may forage on weed stalks as well as in large trees.
