Abstract
Nest-record cards (770) of the Eastern Yellow Robin E. australis were available at the end of the 1980-1 breeding season, .apprx. 1/4 being from the Moruya district of New South Wales. They provided details but little new information on habitat, nest and nest sites, except that the birds probably nest high in forest trees more often than was supposed. Laying was at intervals of .apprx. 27 h. Clutch size averaged 2.33 without any detectable differences between years, places or altitudes but increasing from 2.16 before to .apprx. 2.5 after Oct. The incubation period was just under 16 days and the nestling period 10-14 days. Breeding success was .apprx. 30%, apparently decreasing from 33% before Oct. to .apprx. 20% in Nov. and Dec.; the most frequent clutch size (2) was most frequently successful but clutches of 3 raised more young per nest than did clutches of two. The breeding season started at the end of July or in early Aug. and stopped quite abruptly at the end of Dec., with the main peak of laying from mid-Sept. to mid-Oct. More nests were started before 31 Aug. in Victoria than at Moruya. The analysis was dominated and distorted by the quantity and quality of records from Moruya and few useful comparisons could be made between the results from there and from elsewhere.
