What strategy to choose? Migration distance and body condition as modulators of migration and stopover behaviors in Arctic-breeding waders
(International Wader Study Group, 2020-12-01)
In this series from Wader Study, coordinated by Thomas Mondain-Monval (Lancaster University, UK, t.mondain-monval@lancaster.ac.uk), invited authors discuss themes in wader/shorebird biology, ecology or conservation that ...
Long-Distance Range Expansion and Rapid Adjustment of Migration in a Newly Established Population of Barn Swallows Breeding in Argentina
(Cell Press, 2017-04-03)
When bird populations spread, long-distance pioneering populations are often backfilled by a more slowly advancing front [1–3]. The Barn Swallow Hirundo rustica, a globally distributed passerine [4, 5], expanded its breeding ...
An overview of migratory birds in Brazil
(2018-01-01)
We reviewed the occurrences and distributional patterns of migratory species of birds in Brazil. A species was classified as migratory when at least part of its population performs cyclical, seasonal movements with high ...
Intra-tropical migration and wintering areas of Fork-tailed Flycatchers (Tyrannus savana) breeding in Sao Paulo, Brazil
(Soc Brasileira Ornitologia, 2016-06-01)
Fork-tailed Flycatchers (Tyrannus s. savana) breed from central to southern South America from September to January, migrating to northern South America to spend the non-breeding season. However, little is known of the ...
Intra-tropical migration and wintering areas of Fork-tailed Flycatchers (Tyrannus savana) breeding in São Paulo, Brazil
(2016-06-01)
Fork-tailed Flycatchers (Tyrannus s. savana) breed from central to southern South America from September to January, migrating to northern South America to spend the non-breeding season. However, little is known of the ...
The potential for comparative research across New World bird migration systems
(Wiley Blackwell Publishing, Inc, 2012-08)
For a migratory bird, the costs and benefits of utilizing a given migratory strategy vary according to the biotic (e. g., physiology) and abiotic (e. g., weather) constraints it experiences throughout the year. In the New ...
East with the Night: Longitudinal Migration of the Orinoco Goose (Neochen jubata) between Manú National Park, Peru and the Llanos de Moxos, Bolivia
(Public Library of Science, 2012)
We report on the intra-Amazonian migration of a pair of Orinoco Geese (Neochen jubata) from Manú National Park, Peru. The species is Critically Endangered in Peru, so a major aim of the study was to aid conservation planning ...
Future climate change will impact the size and location of breeding and wintering areas of migratory thrushes in South America
(2021-02-01)
Bird migration patterns are changing worldwide due to current global climate changes. Addressing the effects of such changes on the migration of birds in South America is particularly challenging because the details about ...
Breeding latitude predicts timing but not rate of spring migration in a widespread migratory bird in South America
(Wiley-Blackwell, 2019-05-01)
Identifying the processes that determine avian migratory strategies in different environmental contexts is imperative to understanding the constraints to survival and reproduction faced by migratory birds across the planet. ...
Skuas (Stercorarius spp.) moult body feathers during both the breeding and inter-breeding periods: implications for stable isotope investigations in seabirds
(Wiley Blackwell Publishing, Inc, 2017-04)
Seabirds are mostly thought to moult during the inter-breeding period and the isotopic values of their feathers are often therefore assumed to relate to their assimilated diet during such periods. We observed Brown Skuas ...
