Stopover Ecology of Red Knots in Southwestern James Bay During Southbound Migration

The Journal of Wildlife Management, 2021
ABSTRACTMany shorebirds rely on small numbers of staging sites during long annual migrations. Numerous shorebird species are declining and understanding the importance of these staging sites is important for successful conservation. We surveyed endangered rufa red knots (Calidris canutus rufa) staging in James Bay, Ontario, Canada, during southbound ...

Stopover ecology of fall migrating landbirds at an inland stopover site in northeastern Pennsylvania dominated by nonnative vegetation

The Wilson Journal of Ornithology, 2020
Landbirds are especially vulnerable during migration as they move through novel habitats and encounter enhanced predation risk, unpredictable food resources, enhanced competition, and inclement weather. Further, numerous studies suggest exotic vegetation species have the potential to alter habitat quality, in turn affecting the fitness of migratory ...

Spring Stopover Ecology of Migrant Western Sandpipers

The Condor, 1998
We describe stopover ecology for 132 migrant radiomarked Western Sandpipers (Calidris mauri) relocated repeatedly along the Pacific Flyway of North America. Eighty-eight percent of radiomarked birds were detected at 1-5 sites north of their banding sites, at distances ranging from 240-4,000 km away.

Stopover Ecology and Habitat Use of Migratory Wilson's Warblers

The Auk, 1998
The conservation of long-distance migratory songbirds is complicated by their life-history characteristics and the spatial scales that they traverse. Events during mi- gratory stopovers may have significant consequences in determining the population status of migratory songbirds.

Stopover ecology of migratory Sedge Warblers (Acrocephalus schoenobaenus) at Eilat, Israel

Ostrich, 2004
Migrating Sedge Warblers Acrocephalus schoenobaenus were captured in Eilat, Israel, during their spring and autumn migration. Data on spring and autumn body masses, their interannual variation and the pattern of fuel accumulation were analysed. Body mass and body condition index significantly varied between the years of study in spring but not in ...

Stopover ecology of migrating birds in Indiana

2020
Billions of birds migrate annually between breeding and wintering habitats, following transient resources. Though a majority of time is spent in breeding and wintering habitats, habitats used during the migratory periods are especially important for migrating birds.

AGE-SPECIFIC STOPOVER ECOLOGY OF BLACK BRANT AT HUMBOLDT BAY, CALIFORNIA

The Wilson Journal of Ornithology, 2007
Abstract We analyzed capture-mark-recapture (CMR) data from 1,061 Black Brant (Branta bernicla nigricans) using Humboldt Bay, California, during northward migration (Jan–May), 2000–2001. We estimated immigration and emigration rates, and calculated stopover duration (length of stay), volume (total number of birds using the Bay), and chronology (time ...

Flight Costs, Flight Range and the Stopover Ecology of Migrating Birds

The Journal of Animal Ecology, 1997
1. Flight range equations are a central component in the analysis of avian migration strategies. These equations relate the distance that can be covered to the fuel load that the birds carry. Models of stopover decisions deal with the question of how birds should react to variations in fuel deposition rates.
