MOVEMENTS OF GREY TEAL Anas gracilis FROM A DRYING, ARID ZONE WETLAND
Posted: 11/08/2021Grey Teal (746) were banded on Lake Salisbury, an ephemeral lake in north-western New South Wales in June 1987, before the lake dried. By June 1991, 19 of these birds had been shot by hunters in south-eastern Australia, and their bands recovered. Such recoveries show that Grey Teal, including juveniles, travel to wetlands in south-eastern […]

Read MoreTHE EFFECT OF DROUGHT-BREAKING RAIN ON THE RE-ESTABLISHMENT OF EGRET COLONIES IN NORTH COASTAL NEW SOUTH WALES
Posted: 11/08/2021The re-establishment of five breeding colonies of egrets on the north coast of New South Wales was monitored over a period during which drought-breaking rain fell. Colonisation was affected by the water level of the colony site prior to this rainfall event. Dry sites were not colonised until flooding of the site occurred whilst those […]
Read MoreESTIMATING SEXES OF NEW HOLLAND AND WHITE-CHEEKED HONEYEATERS FROM HEAD-BILL MEASUREMENTS
Posted: 11/08/2021We tested the degree to which New Holland and White-cheeked Honeyeaters could be sexed on the basis of head-bill measurements. Both species showed bimodal distributions of head-bill measurements, with inter-modal troughs at 41.25 mm in New Holland Honeyeaters and at 40.75 mm in Whitecheeked Honeyeaters. We proposed that birds with head-bill measurements greater than the […]

Compared with another population of Eastern Spinebills in the New England National Park, the one at Blue Gum Swamp Creek appeared to have a higher proportion of sedentary birds, had […]
