The foraging ecology of yellow-billed and red- billed choughs changed between two climatically different years [PDF]

Scientific Reports, 2023
Climate change is affecting the alpine ecosystem at an unprecedented rate, with marked changes in spring phenology and the elevation distribution of birds.

Inter- and intra-annual differences in foraging ecology of the chick-rearing Brünnich’s guillemots (Uria lomvia) breeding in the High Arctic [PDF]

Royal Society Open Science
The foraging ecology of seabirds depends on both external and internal factors. Seabirds can modify their feeding strategy depending on current food availability to maintain optimal energy levels provisioned to the offspring. Here, we investigated inter-

Foraging ecology drives social information reliance in an avian eavesdropping community [PDF]

Ecology and Evolution, 2019
Vertebrates obtain social information about predation risk by eavesdropping on the alarm calls of sympatric species. In the Holarctic, birds in the family Paridae function as sentinel species; however, factors shaping eavesdroppers' reliance on their ...

Epibionts Reflect Spatial and Foraging Ecology of Gulf of Mexico Loggerhead Turtles (Caretta caretta)

Frontiers in Ecology and Evolution, 2021
Sea turtles are exposed to numerous threats during migrations to their foraging grounds and at those locations. Therefore, information on sea turtle foraging and spatial ecology can guide conservation initiatives, yet it is difficult to directly observe ...

Kinematics and energetics of foraging behavior in Rice’s whales of the Gulf of Mexico

Scientific Reports, 2023
Rorqual foraging behavior varies with species, prey type and foraging conditions, and can be a determining factor for their fitness. Little is known about the foraging ecology of Rice’s whales (Balaenoptera ricei), an endangered species with a population

The Sensory and Cognitive Ecology of Nectar Robbing

Frontiers in Ecology and Evolution, 2021
Animals foraging from flowers must assess their environment and make critical decisions about which patches, plants, and flowers to exploit to obtain limiting resources. The cognitive ecology of plant-pollinator interactions explores not only the complex

Adaptive Lévy processes and area-restricted search in human foraging [PDF]

, 2013
A considerable amount of research has claimed that animals’ foraging behaviors display movement lengths with power-law distributed tails, characteristic of Lévy flights and Lévy walks.

Loggerhead turtles (Caretta caretta) use vision to forage on gelatinous prey in mid-water. [PDF]

PLoS ONE, 2013
Identifying characteristics of foraging activity is fundamental to understanding an animals' lifestyle and foraging ecology. Despite its importance, monitoring the foraging activities of marine animals is difficult because direct observation is rarely ...

Intraspecific differences in short- and long-term foraging strategies of reef manta ray (Mobula alfredi) in the Chagos Archipelago

Global Ecology and Conservation, 2023
Assessing the foraging ecology of a threatened species is necessary to understand their movement behaviour and habitat use patterns, which are essential for developing effective protection strategies. Here, the foraging ecology of reef manta rays (Mobula

Seasonal distribution and foraging occurrence of Cook Inlet beluga whales based on passive acoustic monitoring

Endangered Species Research, 2020
A paucity of information on the basic biology and ecology of Cook Inlet beluga whales Delphinapterus leucas remains a decade after the species was listed as endangered in 2008. The causes of its continued decline remain unclear.
