Bird Migration at the Edge – Geographic and Anthropogenic Factors but Not Habitat Properties Drive Season-Specific Spatial Stopover Distributions Near Wide Ecological Barriers

Frontiers in Ecology and Evolution, 2022
Stopping-over is critical for migrating birds. Yet, our knowledge of bird stopover distributions and their mechanisms near wide ecological barriers is limited.

Mass gain and stopover dynamics among migrating songbirds are linked to seasonal, environmental, and life-history effects

Ornithology, 2022
During migration, birds must stopover at refueling sites to replenish energy stores, with the rate of refueling linked to stopover length, migration speed, and the timing of critical life stages, such as breeding.

Avian Use of Agricultural Areas as Migration Stopover Sites: A Review of Crop Management Practices and Ecological Correlates

Frontiers in Ecology and Evolution, 2021
An estimated 17% of migratory bird species are threatened or near threatened with extinction. This represents an enormous potential loss of biodiversity and cost to human societies due to the economic benefits that birds provide through ecosystem ...

Landscape movements of migratory birds and bats reveal an expanded scale of stopover. [PDF]

PLoS ONE, 2011
Many species of birds and bats undertake seasonal migrations between breeding and over-wintering sites. En-route, migrants alternate periods of flight with time spent at stopover--the time and space where individuals rest and refuel for subsequent ...

Are movements of daytime and nighttime passerine migrants as different as day and night?

Ecology and Evolution, 2020
Even after decades of research, the migration of songbirds still holds numerous secrets. Distinct stopover and routing behavior of diurnally and nocturnally migrating songbirds has been stated in the 1960s, but empirical confirmation is yet lacking ...

Hydrological modelling for siberian crane Grus Leucogeranus stopover sites in northeast China. [PDF]

PLoS ONE, 2015
Habitat loss is one of the key factors underlying the decline of many waterbird species, including Siberian Crane (Grus leucogeranus), a threatened species worldwide. Wetlands are the primary stopover for many waterbirds and restoration of these wetlands

Differences in stopover duration and body mass change among Emberiza buntings during autumn migration in the Russian Far East

Journal of Ornithology, 2022
Stopover periods between flights are essential for migrating birds, and the time birds spend at stopover sites as well as the refuelling rate is determined by intrinsic and extrinsic factors, such as competition and environmental conditions.

Sandpipers go with the flow: Correlations between estuarine conditions and shorebird abundance at an important stopover on the Pacific Flyway

Ecology and Evolution, 2021
Estuaries of major rivers provide important stopover habitat for migratory birds throughout the world. These estuaries experience large amounts of freshwater inputs from spring runoff.

Seasonal Variations in the Gut Fungal Communities of Hooded Crane (Grus monacha) at Wintering and Stopover Sites in China

Animals, 2021
Simple Summary The gut fungi assist the host in various physiological activities, homeostasis, immune responses, and growth. The diversity and community composition of gut fungi are driven by multiple factors, including diet, environmental exposure ...

Trade-offs, condition dependence and stopover site selection by migrating sandpipers [PDF]

, 2002
Western sandpipers Calidris mauri on southward migration fly over the Gulf of Alaska to the Strait of Georgia, British Columbia, where they stop for a few days to replenish reserves before continuing.
