Migratory songbirds and urban window collision mortality: vulnerability depends on species, diel timing of migration, and age class

Avian Conservation and Ecology, 2022
Hundreds of millions of birds are estimated to die annually in North America by colliding with windows, and understanding the species-level correlates of collision mortality is an important step towards mitigation.

Fuelling in front of the barrier—are there age based behavioral differences in Garden Warblers Sylvia borin? [PDF]

, 2014
Garden Warblers Sylvia borin were studied during autumn stopover in Crete before crossing the barrier of the Mediterranean Sea and the Sahara Desert. Birds followed with transmitters show extensive stopover periods, which were longer in first-year birds,

movetrack: An R package to model flight paths from radio‐telemetry networks

Methods in Ecology and Evolution, EarlyView.
Abstract Tracking small‐ to large‐scale movements of animals is important for studying their interactions with the environment, including how they adjust and adapt their migration in response to environmental and human‐induced changes. Despite the technical progress in tracking devices, a major challenge remains for small animals—such as songbirds ...

Migratory connectivity and annual cycle phenology of Rusty Blackbirds (Euphagus carolinus) revealed through archival GPS tags

Avian Conservation and Ecology, 2021
Understanding spatial and temporal movement patterns of migratory birds throughout the annual cycle can help identify potential population threats. The behavior and habitat use of birds during migration and stopover periods is particularly understudied ...

Coastal wetlands in Lianyungang, Jiangsu Province, China: probably the most important site globally for the Asian Dowitcher (Limnodromus semipalmatus)

Avian Research, 2021
Background Despite an increasing number of surveys and a growing interest in birdwatching, the population and distribution of Asian Dowitcher (Limnodromus semipalmatus), a species endemic to the East Asian–Australasian and Central Asian Flyways, remains ...

Modelling the national breeding distribution and population size of an elusive forest bird, the Eurasian Woodcock (Scolopax rusticola)

Ibis, EarlyView.
Understanding the distribution of species is central to conservation biology. Species distribution modelling (SDM) is a standard method used for this purpose, especially for elusive species for which limited occurrence data exist. The Eurasian Woodcock Scolopax rusticola (hereafter Woodcock) is an elusive, woodland‐dwelling wader that is declining in ...

Predicting effects of environmental change on a migratory herbivore [PDF]

, 2015
Changes in climate, food abundance and disturbance from humans threaten the ability of species to successfully use stopover sites and migrate between non-breeding and breeding areas.

Changes in gut microbiota of migratory passerines during stopover after crossing an ecological barrier [PDF]

The Auk, 2017
ABSTRACT The gut microbiota is a large and diverse community of microorganisms that provides many beneficial functions to the animal host; however, any change in the host's external or internal environment can affect microbiota composition. Migratory passerines arriving at stopover sites show highly variable microbiotas, which is likely reflective of ...

Exploring drivers and costs of partial trans‐Saharan migration in juvenile vultures

Ibis, EarlyView.
Partial migration occurs when only a subset of individuals within a population undertakes a migratory journey. The decision to migrate can be influenced by intrinsic traits (e.g. sex or physical condition) as well as by extrinsic factors (e.g. social environment or resource availability).

Exploring the exploration: implications of leaving or remaining at the natal site during the early stages of independence in a partially migratory bird

Ibis, EarlyView.
Despite being an important fraction of any animal population, juveniles are a severely understudied group. Juveniles often need to learn an array of skills that allow them to survive independently and do so while undertaking decisions that may impact their fitness, recruitment and survival, having therefore relevant demographic implications.
