Effect of geolocators on migration and subsequent breeding performance of a long-distance passerine migrant. [PDF]

PLoS ONE, 2013
Geolocators are small light-weight data loggers used to track individual migratory routes, and their use has increased exponentially in birds. However, the effects of geolocators on individual performance are still poorly known.

Family living sets the stage for cooperative breeding and ecological resilience in birds

PLoS Biology, 2017
Cooperative breeding is an extreme form of cooperation that evolved in a range of lineages, including arthropods, fish, birds, and mammals. Although cooperative breeding in birds is widespread and well-studied, the conditions that favored its evolution ...

Insect ectoparasites on wild birds in the Czech Republic during the pre-breeding period

Parasite, 2011
Wild passerine birds (Passeriformes) from the northeastern part of the Czech Republic were examined for ectoparasites during the pre-breeding period in 2007. Two species of fleas of the genera Ceratophyllus and Dasypsyllus (Siphonaptera: Ceratophyllidae),

Using marine isoscapes to infer movements of oceanic migrants: The case of Bulwer's petrel, Bulweria bulwerii, in the Atlantic Ocean. [PDF]

PLoS ONE, 2018
Studying the movements of oceanic migrants has been elusive until the advent of several tracking devices, such as the light-level geolocators. Stable isotope analysis (SIA) offers a complementary approach to infer areas used year-round, but its ...

No “carry-over” effects of tracking devices on return rate and parameters determining reproductive success in once and repeatedly tagged common swifts (Apus apus), a long-distance migratory bird

Movement Ecology, 2022
Background To understand life-history strategies in migratory bird species, we should focus on migration behaviour and possible carry-over effects on both population and individual level.

Bobolink (Dolichonyx oryzivorus) Declines Follow Bison (Bison bison) Reintroduction on Private Conservation Grasslands

Animals, 2021
Among the most rapidly declining birds in continental North America, grassland birds evolved with American bison (Bison bison) until bison nearly became extinct due to overhunting.

Preferred Habitat of Breeding Birds May Be Compromised by Climate Change: Unexpected Effects of an Exceptionally Cold, Wet Spring

PLoS ONE, 2013
Previous studies of the consequences for breeding birds of climate change have explored how their populations may respond to increasing temperatures.

Neuroendocrine regulation of gonadotropin secretion in seasonally breeding birds

Frontiers in Neuroscience, 2013
Seasonally breeding birds detect environmental signals, such as light, temperature, food availability, and presence of mates to time reproduction. Hypothalamic neurons integrate external and internal signals, and regulate reproduction by releasing ...

Annual migratory movement, apparent molt-migration, migration schedule, and diffuse migratory connectivity of Hermit Warblers

Avian Conservation and Ecology
Quantifying migratory connectivity and annual movement is key to sound conservation planning for migratory species. Hermit Warblers ( Setophaga occidentalis ) are an endemic-breeding species in the Pacific Northwest that winters in Mexico and the Central

Variability in Arrival Time of White Storks (Ciconia ciconia L.): Impact of Age, Interindividual Variation, and Global Change

Frontiers in Ecology and Evolution, 2022
Global changes are inducing migratory birds to advance their annual cycle. However, changes in the time of arrival at their breeding grounds have significant fitness implications.
