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 […]
Read MoreThe 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 […]
Read MoreData are from four nests observed prior to incubation and a different two from incubation through chick independence. The breeding male Intermediate Egret is estimated to spend 22 per cent more time at the nest than the female, due to him spending twice as long there during pre-incubation, on average. The sexes made the same […]
