Two sides of a coin: ecological and chronobiological perspectives of timing in the wild
Most processes within organisms, and most interactions between organisms and their
environment, have distinct time profiles. The temporal coordination of such processes is …

Eye region surface temperature reflects both energy reserves and circulating glucocorticoids in a wild bird
Body temperature of endotherms shows substantial within-and between-individual variation,
but the sources of this variation are not fully understood in wild animals. Variation in body …

Bitter fruits of hard labour: diet metabarcoding and telemetry reveal that urban songbirds travel further for lower-quality food
Rapidly increasing urbanisation requires mitigation against associated losses of biodiversity
and species abundance. In urban-breeding birds, altered food availability for nestlings is …

Limited heat tolerance in an Arctic passerine: Thermoregulatory implications for cold‐specialized birds in a rapidly warming world
Arctic animals inhabit some of the coldest environments on the planet and have evolved
physiological mechanisms for minimizing heat loss under extreme cold. However, the Arctic …

Experimental evidence that hyperthermia limits offspring provisioning in a temperate-breeding bird
In many vertebrates, parental care can require long bouts of daily exercise that can span
several weeks. Exercise, especially in the heat, raises body temperature, and can lead to …

Using facial infrared thermography to infer avian body temperatures in the wild
L Gauchet, A Jaeger, D Grémillet - Marine Biology, 2022 - Springer
Studies performed in humans and farm animals indicate that infrared thermography can be
used to estimate the body temperature of homeotherms. However, this method has seldom …
