In many species, individuals benefit from social associations, but they must balance these
benefits with the costs of competition for resources. Understanding how these competing …

Foraging individuals can benefit from recruiting conspecifics to food sites, but must balance
potential benefits against increased competition. Foragers in fission–fusion societies may …

This paper presents information on the depredations of rose-ringed parakeet (Psittacula

Roost counts may be a useful method for assessing and monitoring parrot populations as
long as counting regimes can detect real differences in abundance above the noise of daily …

Many species have been reported to form roosting (resting, sleeping) aggregations at
'traditional'sites, but the alternative hypothesis that specific sites are used repeatedly …

Learned vocalizations play a key role in parrot social dynamics and vocal dialects have
been documented for several mainland species, but to date no studies of geographically …

Many parrot populations are threatened with extinction due to habitat loss and collection for
the pet trade. The loss of nest trees and chick poaching can drastically reduce reproductive …

Availability of suitable roosting sites influences distribution of wild turkeys (Meleagris
gallopavo) across the landscape. In semi‐arid environments, roosts are limited to riparian …

[EN] Predation pressure by native species may limit the spread of alien invasive species,
thus playing a pivotal role in the impact and implementation of management strategies. The …

'Tradition'has been invoked to explain instances in which animals aggregate repeatedly in
the same locations for no apparent reason, but alternative explanations, such as cryptic …
