Low frequencies of prey stealing behaviour were exhibited by Silver Gulls in Black-naped Tern and Crested Tern colonies on a tropical sand cay on the northern Great Barrier Reef, Queensland. Egg predation by Silver Gulls in Black-naped Tern colonies was lower at this site compared with a southern Great Barrier Reef locality. Chick mortality attributed […]

Hierarchical cluster analysis of morphological data (total head length, exposed culmen and tarsus) from 56 Crested Terns Sterna bergii from south-east Tasmania enabled the identification of an individual’s sex. Both total head length and exposed culmen can be used to differentiate the sexes as there is no overlap present. Tarsal lengths, due to a large […]

Red-browed Firetails Neochmia temporalis dehusked seeds before swallowing them. Smaller seeds were dehusked at a faster speed than larger seeds, but despite this, intermediate-sized seeds, between 1.5 mm and 2.0 mm in width, provided the best energy returns. When given a choice at feeders, Red-browed Firetails consumed seeds of intermediate dimensions more frequently than larger […]

The breeding of Double-banded Plovers Charadrius bicinctus was examined at the Cass River Delta and Kaitorete Spit in Canterbury, New Zealand. Breeding territories were mapped and the mean distance between nests was similar at both localities. Of the nests found, 80 per cent were on vegetated shingle. Laying began in mid-August and reached a peak […]
