Abstract During the dry season months of May to August, a number of the Top End's most widespread tree species flower, including the Darwin Woollybutt Eucalyptus miniata, the Darwin Stringybark E. tetrodonta and the Fern-leaved Grevillea Grevillea pteridifolia. As these species are prolific sources of nectar much favoured by nectar-feeding birds (Franklin & Noske 1999, 2000), nectar is an abundant resource at this time of the year over a vast area (Woinarski et al. 2000). This seasonal resource is exploited not only by birds that normally consume nectar – honeyeaters and lorikeets – but also by a range of opportunists including frugivores, insectivores and even granivores and a terrestrial omnivore which rarely feed on nectar at other times of the year (Franklin 1999). Here I report observations of a Sulphur-crested Cockatoo Cacatua galerita feeding opportunistically at flowers and apparently obtaining nectar. Nectar has not previously been reported as a food source for this species in the Top End or elsewhere (Higgins 1999).
