摘要:

SUMMARYRecher, H. F. 1971. Sharing of habitat by three congeneric honeyeaters. Emu 71: 147–152.Two very similar honeyeatersPhylidonyris nigraandP. novaehollandiaeprefer somewhat different habitats and have very different distributions, but in an area of overlap on the central coast of New South Wales both species frequent the same food-plants and may nest in the same habitats. Differences in their use of a common nesting area are not significant, and the species maintain mutually exclusive territories. However, peak-nesting of the birds occurs at different times of the year and the presence of large numbers ofnigranesting in the early spring may reduce the nesting opportunities ofnovaehollandiae.A third species,P. melanops, also occurs withnigraandnovaehollandiae, but it forages differently and nests in a different part of the habitat.
