...M. Guppy; S. Guppy; R. Marchant ABSTRACT Territoriality in birds has been studied for almost 100 years, but a quantitative, simple and common unit which describes the position of a home range or territory on a study site, is lacking. Consequently it is difficult to assess, or to compare, any data...

... characteristics of the forest koala population, including low stable density, large home ranges, preference for high food tree diversity and locally unique food trees (including Allocasuarina torulosa and Syncarpia glomulifera ), are not adequately explained by existing koala habitat models. We present a new...

... of their switching their prey base to endemic land birds and breeding seabirds. Simultaneous point surveys and radio-tracking of two female owls over 14 months in 2009–2010 indicated that owls occupied small overlapping home ranges with smaller discrete home range cores. The population of Tyto novaehollandiae...

..., mean abundance of P. v. minor was 0.24 ha-1 in wet sclerophyll and 0.38 ha-1 in dry sclerophyll forest. Field observations (n= 330) were collected from nine radio-collared animals across three field sites from July to October 2019. 95% kernel home range estimates varied, ranging from 1.03 – 11.45 ha...

... scale that is unrelated to dingo home range size, space use and life history. In turn, the certainty of ecological conclusions is constrained. Here we discuss the difficulties and limitations of much of the dingo research previously undertaken, including our own, and discuss the benefits of long-term...

... population, we discuss a number of possible explanations for this pattern. These include high availability of prey (in particular, arboreal mammals), quality and spatial extent of habitat, low density of competitors, and relatively small home range sizes of females compared to those in other areas. We...

.... Therefore, it seems implausible to argue that calling adult males are occupying habitat that is devoid of, or independent of, adult females (see below about results from radio-tracking that show males and females have overlapping home ranges). Ellis et al. (2015) stated we suggest that male mating-season...

... populations, such as at a wildlife interface, population density, distribution, and the behaviour of the populations such as pack size, home range and seasonality, or spatial variation of movements might be required, to reflect the nature of interaction between the populations. This contact heterogeneity...

... by Hollands (1991) and Cann et al. (2002). In an investigation of the behaviour of the Masked Owl in a semi-urban landscape near Newcastle, Kavanagh and Murray (1996) tracked an adult female identifying the home range and breeding territory. A portion of this same breeding territory was later approved...

... of Western Sydney, Campbelltown, now exceeds 3500. Many of the records from the bushland/ suburban interface, however, are multiple sightings of female Koalas in established home-ranges. Females occupy most of the suitable habitat in the region and local residents often see them (unpublished data). More than...
