TERRITORIALISM AND CO-OPERATIVE BREEDING OF THE EASTERN YELLOW ROBIN Eopsaltria australis

Posted: 21/09/2021
Author(s): S. MARCHANT

I studied the Eastern Yellow Robin Eopsaltria australis from 1975 to 1986 near Moruya. N.S.W. The birds were distributed in territories of 1 to 2 hectares. A fire in 1980 did not at once reduce breeding numbers; they declined next season. Established pairs held territories while breeding. In the non-breeding season they lived in the […]

Rufous Whistlers Pachycephala rufiventris and Leaden Flycatchers Myiagra rubecula are breeding visitors to the area. Some individuals return to the same territory in successive years. Yellow-faced Honeyeaters Lichenostomus chrysops and Silvereyes Zosterops lateralis are common passage migrants and winter visitors. Both have small breeding populations near Armidale and remain within, or return to, the same […]

POPULATION OF THE SILVER GULL Larus novaehollandiae ON THE CAPRICORN AND BUNKER ISLANDS, GREAT BARRIER REEF

Posted: 16/09/2021
Author(s): T. A. WALKER

Silver Gulls were censused from January 1983 to March 1985 on the Capricorn and Bunker Islands. Gulls moved between the islands, congregating at sites where food scraps and people were most abundant. Such sites were permanent, as at Heron Island, or temporary when campers and fishermen were present at other islands. On winter days up […]

Breeding birds started to moult in November after most progeny were feathered but before they had fledged. Females took less time to moult […]
