Attention is drawn to deficiencies in some methods of estimating survival, including ‘known to be alive’ or ‘calendar of captures’ methods. The Jolly-Seber model is recommended for estimation of survival, population size and recruitment from capture-recapture data. The Jolly-Seber model is described and used to analyse banding data collected from 184 Bridled Honeyeaters at Paluma, […]
Scarlet Honeyeaters were banded at a study site at Mount Cotton, south-east Queensland from 1986 to 1993. The site consisted of sclerophyll woodland, creek vegetation and a rural garden. There was a marked seasonal change in Scarlet Honeyeater abundance, with numbers increasing from a minimum in March to a maximum in August followed by a […]
The corroboree or congregation display occurs in a number of honeyeater species. This paper presents data on the display of New Holland Honeyeaters in New England National Park. Corroboree frequency is highest in the morning (0.85 displays/hr) and peaks in late summer and winter (up to 3.3 displays/hr) when breeding territories are being established. The […]
Field surveys of large owls were undertaken in coastal, escarpment and tableland forests of north-east New South Wales in 1990-92. A combination of listening, playback of taped calls and spotlighting was used at 401 sites. Of these, 354 sites were surveyed at least twice each. Powerful Owls Ninox strenua were recorded at 76 sites (1 […]
