摘要

Little is known about the breeding biology of Bridled White-eyes (Zosterops conspicillatus), especially the federally endangered Rota Bridled White-eye (Z c. rotensis). Here, we report on the breeding behavior, nest-site characteristics, and nest dimensions of Rota Bridled White-eyes. From 1997 to 1999, we found 20 Rota Bridled White-eye nests in Elaeocarpus joga (35%), Hernandia lahyrinthica (30%), Merrillio-dendron megacarpum (20%), and introduced Acacia confusa (15%) trees between 320 and 460 m in elevation. Nests were 2.5-12.8 m above the ground (n = 18) in trees 3.3-14.6 m tall (n = 16). Clutch size ranged from one to two eggs (n = 7) and the breeding season was from at least December through August. Nest dimensions (n = 4) were 36-44 x 57.7-60.8 mm (outer height x diameter) and 25-29 x 44.6-47.7 mm (cup depth x diameter).
