The breeding of the Wedge-tailed Eagle Aquila audax was investigated in four areas of the arid zone of Western Australia from 1968 to 1976, with some supporting data from the adjacent Mediterranean zone. Breeding was dependent on, and geared to, the

Parasitic cuckoos of the genus Clamator and parasitic cowbirds Molothrus spp. lay eggs that appear to be stronger than those of their hosts. Similar differences in eggshell strength between the eggs of the Cuculus/Cacomantis/Chrysococcyx cuckoos and

The breeding behaviour of two similarly sized sympatric cuckoos, Horsfield's Bronze-Cuckoo Chrysococcyx basalts and the Shining Bronze-Cuckoo C. lucidus, was studied over four breeding seasons at Gooseberry Hill, Western Australia. Both cuckoos usual

The distribution of Blue-breasted Fairy-wrens, Malurus pulcherrimus, in 12 million hectares of the central wheatbelt of Western Australia was determined from 'presence/absence' records obtained from a search of 273 10′ blocks of latitude and longit

A colour-banded population of Malurus splendens was studied from 1973-1988 in up to 34 cooperativebreeding territorial groups in woodland-heath near Perth. The study is considered in three parts: 1973-77, with regular minor patchy fires; 1978-84, wit

Cuckoos (Cuculinae) provide examples of a highly evolved host-parasite interaction where the parasite lays eggs adapted in colour and size toward those of its hosts. Egg colour adaptation in cuckoos could be either (a) a response to egg rejection beh

We studied blue-breasted fairy-wrens, Malurus pulcherrimus, over a 6-year period in 17 differently sized remnants in a highly fragmented agricultural landscape at Wyalkatchem, Western Australia. The wrens lived in groups of 2–5 adults, comprising o
