Two Regent Honeyeater Xanthomyza phrygia nests were watched for six days before both nests
disappeared. Observations on nest building, copulation, incubation, feeding, vocalizat1on and aggressive
interactions with other avian species are presented. There was frequent aggression between the
Regent Honeyeaters and other species of honeyeaters. lt is possible that habitat fragmentation coupled
with frequent and intense interspecific aggression during breeding are contributing factors 111 the
decline of Regent Honeyeater populations.
