The physiology of movement [PDF]
, 2020 Movement, from foraging to migration, is known to be under the influence of the environment. The translation of environmental cues to individual movement decision making is determined by an individual's internal state and anticipated to balance costs and

Frontiers in Ecology and Evolution, 2022 Billions of birds migrate every year. To conduct a successful migration, birds undergo a multitude of physiological adaptions. One such adaptation includes adjustments of immune function, however, little is known about intraspecies (between-individual ...

Migratory stopover sites used by Reddish Egrets: prioritization for conservation
Avian Conservation and Ecology, 2022 The conditions encountered during the migratory period, particularly at stopover sites, can influence individual survival, reproductive success, and population stability; therefore, knowledge of migration ecology is important for developing conservation ...

Avian Haemosporidian blood parasite infections at a migration hotspot in Eilat, Israel [PDF]
, 2016 Haemosporidian blood parasites are frequent amongst passerines. Though they often do not cause detectable consequences to host health, however, their presence or absence and also their prevalence across host populations may potentially carry ...

Spring migration of Ruffs Philomachus pugnax in Fryslân: estimates of staging duration using resighting data [PDF]
, 2010 Seasonal bird migration involves long flights, but most time is actually spent at intermediate staging areas. The duration of stay at these sites can be evaluated with mark–recapture methods that employ day-to-day local encounters of individually marked ...

Feather growth rate and mass in nearctic passerines with variablemigratory behavior and molt pattern [PDF]
, 2012 Bird species vary greatly in the duration of their annual complete feather molt. However, such variation is not well documented in birds from many biogeographic areas, which restricts our understanding of the diversification of molt strategies.

Breeding latitude predicts timing but not rate of spring migration in a widespread migratory bird in South America [PDF]
, 2019 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.

Birds, 2022 The overall speed of bird migration is limited by the amount of fuel stores acquired during the initial phases of migration. The ability to mobilize fat is crucial for migratory birds that can exhibit different migratory strategies.

Neotropical Bird Migration During The Ice Ages: Orientation And Ecology [PDF]
, 1996 Reconstruction of breeding habitat of North American Neotropical migrants 18,000 years ago and 9,000 years ago indicated major shifts in both location and composition of plant communities relative to present conditions.
