Abstract
Parts of the breeding cycle of a pair of Black-breasted Buzzards Hamirostra melanosternon were observed near Alice Springs, Northern Territory, in 2014 and 2015, when the pair raised a single fledgling in each year. Supplementary information was obtained on pre-laying behaviour, vocalisations, nest defence and chick growth. Our study confirmed allopreening and use of the piping call in the pre-laying phase; male use of the wheezing call; and gender roles in defence at different stages; and highlighted further similarities with the Square-tailed Kite Lophoictinia isura.
