Guided by the light: Roost choice and behaviour of urban Rainbow Lorikeets (Trichoglossus haematodus)

Investigating the selection of roosting sites in the Rainbow Lorikeet in Brisbane, Australia found a clear preference for clumped trees within sparsely treed areas that received significantly more artificial light at night than otherwise suitable sites and trees nearby, suggesting a potential positive impact of anthropogenic lighting.

Effect of weather conditions on the communal roosting behaviour of common ravens Corvus corax with unlimited food resources

Examination of roosting times of common ravens in Thuringia, Germany, found flexible time–activity budgets resulting from a superabundant food supply may have enabled ravens to moderate the effects of environmental conditions on arrival times at the preroost and the roost.

Weather Factors Influencing Winter Roosts of American Crows in Central Iowa

We investigated the effects of season and weather on the winter roosting behavior of American Crows (Corvus brachyrhynchos) in central Iowa from January through March 2006. The peak number of birds

The Influence of Environmental Cues and Anthropogenic Activity on Roost Departure Times in the Northwestern Crow (Corvus caurinus)

ABSTRACT While communal roosting is fairly common in animals, the costs, benefits, and proximal factors influencing this behavior are poorly understood. Moreover, many species with communal roosting

Variation in breeding parameters of the Australian magpie Gymnorhina tibicen in suburban and rural environments

The breeding ecology of the Australian magpie Gymnorhina tibicen in suburban and rural areas was compared as part of a study into the synanthropy of the species in southeast Queensland, Australia.

Observation of Ground Roosting by American Crows

Abstract Communal winter roosts of American Crows (Corvus brachyrhynchos) often occur in urban areas and may number in the thousands of individuals. We documented the distribution of urban roosts of

Home range, habitat use and movements by the little raven (Corvus mellori) in a coastal peri-urban landscape

Abstract Context. In peri-urban environments, high availability of anthropogenic resources may result in relatively high abundances of some species, with potentially negative implications for other

Crag Martin neontology complements taphonomy at the Gorham's Cave Complex

The results demonstrate extremely fine-scale fidelity at the largest roosting site documented for ECM globally, and provides current knowledge of a bird that has been using these caves since the Pleistocene and more generally on these caves as refuges.

Communal roosting in the Magpie (Pica pica)

Communal roosting of corvid species seems to be related primarily to the distribution and the abundance of food, species with an unpredictable food supply roosts communally rather than solitarily in winter.

Preroosting behaviour of hooded crows (Corvus corone cornix)

Hooded crows flew conspicuously in formation more often and for a longer time when on their way from preroost to roost on days with stronger winds, and as the amount of snowfall during the preceding 24 h increased, an indication of sudden difficulty in finding food, the maximum number of crows that gathered increased.

Roosting and diurnal movements of radio-tagged American Crows

A pattern of fidelity to diurnal activity centers (DAC's) with daily movements to roosts and areas of superabundant food, much like the movements of communally roosting blackbirds and starlings is suggested.

Raven roosts are mobile information centres

Vagrant, non-breeding common ravens,Corvus corax, inhabiting the forested mountains of Maine are specialized to feed on rich but ephemeral carcasses of large mammals during the harsh winter months.

Individual roosting strategies in a flock-living bird: movement and social cohesion of hooded crows (Corvus corone cornix) from pre-roost gatherings to roost sites

Analysis of movement and social cohesion of radio-tagged hooded crows from their daytime location via pre-roost to roost in autumn and winter suggests patterns may be interpreted as supporting several of the current hypotheses on the function of pre- roost gathering.

Characteristics of American Crow Urban Roosts in California

American crows (Corvus brachyrhynchos) roost in urban areas across the United States creating problems resulting from fecal droppings, noise, and health hazards, and a logistic regression model was developed with 4 variables that correctly classified status of 85% of roost or nonroost trees.

Movements and Habitat Use of the Torresian Crow in a Subtropical Suburban Environment

Crows significantly preferred park and edge habitats to forest and suburban habitats, presumably because these areas provide resources for feeding and roosting.

An evaluation of predation by 'crows' on young lambs

Aviary experiments suggest that on the south-east mainland of Australia C. coronoides and C. tasmanicus are the only species capable of damaging lambs, and a change in sheep management, particularly by providing shelter for lambing flocks, will ensure a greater and more permanent improvement in lambing results.

Energy relations of winter roost-site utilization by American goldfinches (Carduelis tristis)

All but two birds sampled could endure a 15-h roost period at average overnight Te's as low as-40°C, and only 30% could survive the imposition of a 39-h fast at average Te's of-2°C.
