Hidden Long-Distance Movements by a Migratory Bird

Abstract Technology has revolutionized our ability to track animals across the globe, significantly advancing our understanding of animal movement. Technological and logistical challenges, however, have led to non-migratory movements that fall outside of the territory/home range paradigm, receiving less attention. This may have resulted in a widespread underestimation of the…

Looking at the forest through the eyes of birds: A radio-tracking study of microhabitat use in provisioning great tits.

Abstract Detailed knowledge of habitat utilization by animals is integral in understanding their ability to adjust resource exploitation to the conditions of heterogeneous and constantly changing habitats. To identify the most important micro- and macrohabitat landscape characteristics that are important factors for birds when choosing foraging patches in their territory,…

Breeding status influences timing but not duration of moult in the Northern Fulmar Fulmarus glacialis.

Abstract Seabirds are key marine top predator species that are often used as indicators of the environmental quality of the oceans. Their breeding phenology has been studied extensively, but their pelagic habits mean less is known about the phenology of other events during the non-breeding period. Here, we used miniaturized…

Bitter fruits of hard labour: diet metabarcoding and telemetry reveal that urban songbirds travel further for lower-quality food.

Abstract Rapidly increasing urbanisation requires mitigation against associated losses of biodiversity and species abundance. In urban-breeding birds, altered food availability for nestlings is thought to reduce reproductive success compared to forest populations. To compensate for shortages of preferred foods, urban parents could increase their search effort for optimal diets or…

Intercolony variation in foraging flight characteristics of black‐headed gulls Chroicocephalus ridibundus during the incubation period. Ecology and Evolution.

Abstract Using GPS loggers, we examined the influence of colony, sex, and bird identity on foraging flight characteristics of black-headed gulls Chroicocephalus ridibundus during the incubation period. We studied tracks of 36 individuals breeding in one urban and two rural colonies in Poland. Birds from both rural colonies performed the…

Early detection of rapid Barred Owl population growth within the range of the California Spotted Owl advises the Precautionary Principle

Abstract Biological invasions are most practical to manage when invasive species population densities are low. Despite a potentially narrow window of opportunity for efficient management, managers tend to delay intervention because the cost of prompt action is often high and resources are limited. The Barred Owl (Strix varia) invaded and…

Hunting activity effects on roost selection by male wild turkeys.

Abstract Roosting is an important component of wild turkey (Meleagris gallopavo; turkey) ecology asroosts provide security from predators and inclement weather. Males call (gobble) from roosts during thereproductive season, and roost locations are important for maximizing access to females and transmission ofcalls across the landscape, while also minimizing predation risk.…

Postfledging habitat selection and survival of Henslow’s Sparrow: management implications for a critical life stage

Abstract Conserving populations of species that rely on rare habitat requires that managers understand which habitat characteristics will best support population growth across multiple life stages. For songbirds, management is most often aimed at nesting adult habitat associations. However, habitat that meets adult requirements may not be similarly suited to…
