Australia's Regent Honeyeater has declined so far that young males are forgetting their own species song. Here is what field biologists are doing about it.

A ground-dwelling tapaculo from Brazil's Atlantic Forest has become a test of how much conservation can do when almost no birds remain.
A short lower chisel and a long upper probe let this Hawaiian honeycreeper work wood in a way no other living bird quite matches.
