Assessment Of Natural Roost Availability And Artificial Roost Preference By Indiana Bats In Scott County, Kentucky
In addition to using natural roosts, Indiana bats (Myotis sodalis) form maternity colonies in artificial roosts such as rocket boxes and bark-mimic structures. However, few Indiana bat study systems contain multiple artificial roost types alongside natural roosting options. I sought to analyze …

Nocturnal roost tree, roost site and landscape characteristics of Carnaby's Black-Cockatoo (Calyptorynchus latirostris) on the Swan Coastal Plain
There is limited information on communal roosting in parrot species of Western Australia and other parts of the world. Carnaby’s Black-Cockatoo is an endangered species that forms large nocturnal communal roosts, and for this reason they are an ideal model species to test the characteristics or …

Thermoregulatory ecology and roost selection of imperiled bat species
Submission original under an indefinite embargo labeled 'Open Access'. The submission was exported from vireo on 2025-10-19 without embargo terms

Maximum Entropy Modeling of Indiana Bat (Myotis Sodalis) Maternity Roost Habitat
… variables associated with Indiana bat maternity roost trees in an attempt to better understand what factors play a role in their distribution in north central Missouri. I tracked reproductive female Indiana bats to 20 different primary and secondary roost trees; these are roosts that had multiple …

Characteristics and Use of Wild Turkey Roost Sites in Southcentral South Dakota
… (Meleagris gallopavo)were monitored to document roost site use and bird movements in the Missouri River breaks complex of southcentral South Dakota during the summer of 1984. Distances between roost sites used by wild turkeys ranged from 0.55 km to 3.09 km. Primary and secondary roost sites were …

Black and turkey vulture roost dynamics, marking, morphology and nesting in Virginia
… atratus) and turkey vulture (Cathartes aura) roosting dynamics were studied at eight roosts near Radford, Virginia. Black vulture numbers at a permanent roost ranged from low monthly means in June 1982 and 1983 to peak monthly means in December 1981 and 1982. Turkey vulture numbers ranged from …

Intersexual roost site selection by the little brown Myotis in Cypress Hills, Saskatchewan
Roost structures provide habitats for bats to engage in critical life processes. Identifying, characterizing, and conserving these structures is crucial for individual fitness and survival to mitigate population loss, especially for species such as the little brown Myotis facing threats such as …

Bat Boxes as Mitigation Tools: Factors Impacting Microclimate and Myotis sodalis Roost Selection
… has led to declines in available natural roosting habitat for bats. To mitigate this loss, practitioners often deploy artificial roosts (e.g., bat boxes). There are no established species-specific practices for deployment strategy and roost design selection, but occupancy rates are known …

Vocalizations influence roost-site selection in overwintering cavity-nesting birds in Eastern Washington
… They increase overwinter survival by night roosting in cavities and forming flocks. The timing of roost site selection can impact the quality of a roost site, thus selecting a roost site too late reduces the odds of selecting the most favorable microclimate available. Birds in flocks use …

Hormones rule the roost: Fluctuations of olfactory functioning throughout the menstrual cycle and during pregnancy
The relationship of olfactory functioning and hormones is complex, and, for the most part, heterogenous. The present study aims to clarify and or define aspects of this relationship by examining how olfactory thresholds fluctuate in relation to changing hormone levels in two populations: …

Community ecology of bats in southern lower Michigan, with emphasis on roost selection by myotis
<p>I studied the roosting niche of three sympatric species of Myotis (little brown bat, M. lucifugus; northern bat, M. septentrionalis; and Indiana bat, M. sodalis) and examined changes in composition of the entire bat community in southern Lower Michigan over long periods. Little brown bats …

Northern long-eared bat day roost ecology and novel bat sampling techniques in the mid-Atlantic
… where little is known about their summertime day-roost habitat needs. More broadly for the species, little research has examined the day-roost habitat use of both male and females. This information is vital to inform management and policy for the conservation of this endangered species. In this …

Roost-Site Selection of Bats in Northeast Missouri With Emphasis on the Endangered Indiana Bat (Myotis Sodalis)
Roosts are an integral habitat component for bat species and may dictate their survival and fitness. I used radiotelemetry to study the roosting ecology of the endangered Indiana bat, Myotis sodalis, at Deer Ridge Conservation Area (DRCA) in northeast Missouri from May through August 2001-2002. Due …

While transmitters were active, skin temperature data were collected using a datalogger and foraging patterns determined …

Day-roosting Social Ecology of the Northern Long-eared Bat (Myotis septentrionalis) and the Endangered Indiana Bat (Myotis sodalis)
Day-roost use by northern long-eared bat (Myotis septentrionalis) maternity colonies on the Fort Knox military reservation, Kentucky, USA, resulted in formation of non-random networks of roosts that exhibited a trend toward centralization. Centralization of day-roost networks was reflected in the …
