Analysis of anthropogenic tolerance of corvids in Zhytomyr urban habitats

Біологічні студії, 2013
The results of studies of anthropogenic tolerance of corvids were performed in Zhytomyr from September 2009 to August 2012. We have chosen the Rook (Corvus frugilegus L.), Western Jackdaw (Corvus monedula L.), and Hooded Crow (Corvus cornix L.) as model ...

Low Nest Success of Black‐Legged Kittiwakes (Rissa tridactyla) at a Mainland Colony Is Not Associated With Disturbance From Walkers or Boats: Implications for Compensation for Offshore Renewables Impacts

Ecology and Evolution, Volume 16, Issue 9, September 2026.
Offshore wind energy is rapidly expanding in the North sea foraging grounds of internationally important seabirds, with predicted impacts on their survival and productivity. Since reduction to breeding colony disturbance is a proposed compensation measure for these impacts, we used a seven‐year dataset of > 1400 black‐legged kittiwake nests at an ...

Sleep and Thermoregulation in Birds: Cold Exposure Reduces Brain Temperature but Has Little Influence on Sleep Time and Sleep Architecture in Jackdaws (Coloeus monedula)

Biology
Birds have an electrophysiological sleep state that resembles mammalian rapid-eye-movement (REM) sleep. However, whether its regulation and function are similar is unclear.

Bird Census Data Do Not Indicate a Lack of Impact on Songbirds From the Growth of Avian Predator Populations in Britain in the Late 20th Century

Frontiers in Ecology and Evolution, 2020
The possible role of avian predators in limiting songbird populations has been largely discounted since the publication of findings showing a lack of statistical association in United Kingdom bird census data between changes in prey species populations ...

Impacted Bones: Can Extant Primates Help Identify Tool Use in Early Hominins?

Evolutionary Anthropology: Issues, News, and Reviews, Volume 35, Issue 3, September 2026.
ABSTRACT Despite recent advances pushing back the earliest record of tool use, how and when it first emerged in hominins, and the extent to which it featured amongst the numerous co‐existing species, remain critical questions in paleoanthropology. In addition to analyzing fossils and lithic toolkits, novel strides in understanding this might be made by

Response of corvid nest predators to thinning: implications for balancing short- and long-term goals for restoration of forest habitat

Avian Conservation and Ecology
Forest thinning on public lands in the Pacific Northwest USA is an important tool for restoring diversity in forest stands with a legacy of simplified structure from decades of intensive management for timber production. A primary application of thinning

Seabird population responses after the removal of an introduced predator

The Journal of Wildlife Management, Volume 90, Issue 7, September 2026.
We studied the response of a breeding population of seabirds (pigeon guillemots) to the removal of an introduced population of predators (American mink) from an archipelago that was formerly the largest aggregation of nesting guillemots in Prince William Sound, Alaska.

Changes in the dopaminergic circuitry and adult neurogenesis linked to reinforcement learning in corvids

Frontiers in Neuroscience
The caudolateral nidopallium (NCL, an analog of the prefrontal cortex) is known to be involved in learning, memory, and discrimination in corvids (a songbird), whereas the involvement of other brain regions in these phenomena is not well explored.

Molecular and Serological Screening of West Nile and Usutu Virus in Birds and Humans: A Sentinel Study in Finland

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
We developed sensitive real‐time PCR assays for West Nile virus and Usutu virus to screen bird and human samples in Finland. Although no positive samples were detected, active migratory flyways and recent cases in neighbouring countries highlight the risk of future introduction and the need for continued surveillance.

Planning and inhibition in corvids [PDF]

, 2017
Executive functions (EF) denote the host of top-down mental processes that mediate self-regulation to achieve a goal. Among other things, EF support cognitive flexibility by allowing inhibition of automatic responses in favour of obtaining future goals ...
