摘要：Red-crowned Ant-Tanager (Habia rubica) inhabits the pacific foothills in Costa Rica. Here I report a new breeding
location for the species, in a river side forest in the north of Central Valley of Costa Rica, 1400 m.a.s.l. Data about a
female nest-helper are included, and this information is the first record of nest-helpers for the species.
