- 摘要:
- and vocalizations, but also thermoregulation. The latter function was neglected until recently, but convincing evidence has been provided about the birds’ capacity
Data from: Cryptic differences in colour among Müllerian mimics: how can the visual capacities of predators and prey shape the evolution of wing

- 摘要:
- was also evaluated to be higher for butterflies than for birds, suggesting that this variation in colour, likely undetectable to birds, might be use
Data from: Activity patterns at the Arctic Circle: nocturnal eagle owls and interspecific interactions during continuous midsummer daylight

- 摘要:
- interactions with their main prey the water vole Arvicola amphibius, and their competitor the white?tailed eagle Haliaeetus albicilla during continuous mids
Data from: Taking a trip to the shelf: behavioural decisions are mediated by the proximity to foraging habitats in the black-legged kittiwake

- 摘要:
- 1. For marine top predators like seabirds, the oceans represent a multitude of habitats regarding oceanographic conditions and food availabi
Data from: Diet of the insectivorous bat Pipistrellus nathusii during autumn migration and summer residence

- 摘要:
- s, for examples, have been shown to occur in birds before onset of migration. For bats it is not known if a change in diet occurs during migration, although esp
Data from: Disentangling the effects of environmental conditions on wintering and breeding grounds on age-specific survival rates in a trans-Saharan

- 摘要:
- onmental conditions and that adverse conditions on wintering grounds can amplify the negative effects of conditions during the previous breeding season on birds’ survival.

Data from: Macronutrient selection of free-ranging urban Australian white ibis (Threskiornis moluccus)

- 摘要:
- One proposed advantage of communal roosting in birds is a reduction in the costs of thermoregulation. As thermoregulatory benefits are dir
