General:
The black-billed nightingale-thrush (Catharus gracilirostris) is a small thrush endemic to the highlands of Costa Rica and western Panama. Its position in the genus Catharus is somewhat equivocal, but it is apparently closer to the hermit thrush than to the other nightingale-thrushes except the russet nightingale-thrush and/or the ruddy-capped nightingale-thrush (Winker & Pruett, 2006).[2]
