A corotú tree (Enterolobium cyclocarpum) was observed from April to September, 2000, at the University of Panama in order to determine the migrant birds related with the tree and how they were distributed in its different sections or strata: ground level, roots, trunk, branches, leaves, flowers and fruits. We detected sixteen species, seven families and two orders in the total plant. No species used all strata, and no stratus had all species. The most exploited strata were branches and leaves, while roots, trunk and fruits were the less used. Feeding was the most frequent activity, and insects were the main food. Migrant birds that subsist supported by E. cyclocarpum can contribute to the control of its insect populations and pollination. The biggest quantity in species and visits were observed when the tree was flourished.
