White-throated Nightjar: A new breeding species for the A.C.T

White-throated Nightjars Caprimulgus mystacalis migrate from northern Australia and New Guinea to the south-eastern coastal strip of Australia each summer (Blakers et al. 1984). They are rare west of the Great Divide, are recorded in the Australian Capital Territory only once every two or three years, and have never been recorded breeding in the A.C. T. (Taylor & COG 1992) or west of the Great Divide in New South Wales. Blakers et al. (1984) recorded their breeding twice on or west of the Divide in southern Queensland. Marchant (1987), working east of the Divide near Moruya in New South Wales, found they normally laid a single egg on a ridge top in early summer.
