Reed warblers migrating through Portugal: climatic influence on stopover ecology over the last decade

Zoology, 2016
The arrival and breeding dates of small migrant birds have advanced throughout Europe. This study evaluates the hypothesis of a faster migration along the migratory route, which should lead to a decrease in stopover duration in staging areas over the last decades.

Stopover ecology of a migratory ungulate.

The Journal of animal ecology, 2012
1. Birds that migrate long distances use stopover sites to optimize fuel loads and complete migration as quickly as possible. Stopover use has been predicted to facilitate a time-minimization strategy in land migrants as well, but empirical tests have been lacking, and alternative migration strategies have not been considered. 2.

Stopover ecology of Red-flanked Bush Robin (Tarsiger cyanurus) at Maoershan, Northeast China

Acta Ecologica Sinica, 2006
bird conservation; The conservation of songbird migrants in China faces challenges similar to those in other parts of the world such as Europe and North America. Songbird migrants have complex life history and are associated with large spatial scale. The events occurred during migration play a critical role in determining population status.

Fat Content and Stopover Ecology of Spring Migrant Semipalmated Sandpipers in South Carolina

The Condor, 1995
Semipalmated Sandpipers (Calidris pusilla) stop at staging areas during migration to replenish fat reserves that fuel long distance flights. We hypothesize that if sandpipers are minimizing time spent en route between wintering areas and breeding grounds, a negative correlation should exist between fat content upon arrival at a staging area and length ...

Stopover ecology of American Golden-Plovers (Pluvialis dominica) in Midwestern agricultural fields

The Condor, 2014
ABSTRACT Stopover locations represent critical habitat in the life cycle of migratory birds and the alteration of this habitat can profoundly influence a population. American Golden-Plovers (Pluvialis dominica) migrate though the Midwestern United States each spring, where most natural habitat has been converted to row crop agriculture. We investigated

Comparison of Migrant Songbird Stopover Ecology on Two Islands in the Gulf of Maine

The Wilson Journal of Ornithology, 2012
Abstract We compared migrant bird recapture rate, stopover time, mass gain, and fat class between Star Island, New Hampshire and Appledore Island, Maine during spring and fall migration in relation to differences in relative species abundance between the islands; and examined potential movement of migrants between the islands.

Stopover Ecology of Transitory Populations: The Case of Migrant Shorebirds

1997
The overviews of prairie vertebrates thus far in this book focus primarily on resident or breeding species of several taxa. A myriad of avian species, including warblers seeking the boreal forests and waterfowl flying to northern wetlands, temporarily inhabit the central Plains as they rest and refuel for their long journeys.

Red Knot Stopover Population Size and Migration Ecology at Delaware Bay, USA, 2021

2022
AbstractRed Knots (Calidris canutus rufa) stop at Delaware Bay during northward migration to feed on eggs of horseshoe crabs (Limulus polyphemus). In the late 1990s and early 2000s, the number of Red Knots found at Delaware Bay dramatically declined from ~50,000 to ~13,000.

Migrant–habitat relationships during stopover along an ecological barrier: extrinsic constraints and conservation implications

Journal of Ornithology, 2011
For migrating land birds, the influence of extrinsic factors (e.g., weather and energetic condition) on stopover site selection relative to factors intrinsic to habitat (e.g., food) may be especially acute after crossing a large ecological barrier. We quantified bird distributions during spring and autumn migration along the coast of Mississippi after ...

Methods for studying stopover ecology of migrating landbirds with weather surveillance radar

2017
"Populations of numerous migratory landbird species in the eastern United States are declining and these populations may be limited during their migratory journey. Weather surveillance radar is a useful tool for monitoring large scale movements of birds during migration and particularly for mapping stopover distributions of migratory landbirds because ...
