Abstract

We present the first detailed descriptions of the breeding biology of the Blue-naped Chlorophonia (Fringillidae; Chlorophonia cyanea). In the Santa Marta Mountains, the Blue-naped Chlorophonia builds domed nests on vegetated roadbanks or roadside cliffs. They generally used existing vegetation to form the dome; in one case we inferred that a pair actively excavated a nest. This species lays a clutch of three eggs, white with reddish-brown speckling. The incubation period is 18-20 days, while the nestling period lasts 20-21 days. Both adults provision the nestlings equally, feeding regurgitated fruit in a stereotyped pattern, with an overall feeding rate of 3.5 feeding trips/hr. The main breeding season of the Blue-naped Chlorophonia in the Santa Marta Mountains is February to May.
