THE BREEDING CYCLE OF THE YELLOW-BELLIED SEEDEATER IN PANAMA
Author(s): CORA C. ALDERTON
This report on the Yellow-bellied Seedeater (Sporophila nigricollis) is part of a fiveyear study of the life histories of some common tropical birds of the Panama Canal Zone. The species is widely distributed in the tropics and occurs in a variety of habitats over a great range of altitude. On the Isthmus of Panamh, it is a “common open-country species” (Eisenmann, Smiths. Misc. Coll., 117, no. 5, 1952: 58).
