Inter‐ and intra‐individual variation in the feather coloration of American crows

open access: yesJournal of Avian Biology, Volume 2026, Issue 2, March 2026.
Avian feathers are remarkably diverse in both form and function. Coloration is among the most studied feature of feathers, but we know relatively little about melanin‐based black coloration. Despite many crows (Corvus sp.) and other corvids having black feathers that appear uniform to human perception, their feather coloration could play an important ...

Functional morphology and integration of corvid skulls - a 3D geometric morphometric approach [PDF]

open access: yes, 2009
BACKGROUND: Sympatric corvid species have evolved differences in nesting, habitat choice, diet and foraging. Differences in the frequency with which corvid species use their repertoire of feeding techniques is expected to covary with bill-shape and with ...

Not just ‘super‐predators': human behaviour shapes wildlife behavioural responses across avoidance, tolerance and attraction

open access: yesOikos, Volume 2026, Issue 3, March 2026.
Humans are thought to have a disproportionately negative impact on wildlife and are viewed by some as the ultimate ‘super predator'. This view implies that wild animals perceive humans primarily as predators. However, a growing body of evidence shows that wildlife can have remarkable tolerance for, or even attraction to, humans.

The impact of roosting birds on the abundance of two groups of soil mesofauna

open access: yesStudia Ecologiae et Bioethicae, 2012
The aim of the study was to assess the influence of corvid urban roosts on the abundance of two groups of soil mesofauna: mites and springtails. Two areas located in the city of Warsaw were taken into consideration, one subjected to winter roosting ...

Crow (Corvus spp.) meat: research possibilities to determine nutritional quality and health risks

open access: yesNutrimentum et Curae
There is very limited (if any) literature on the potential use of corvids, specifically crows, as game meat. Despite the worldwide presence of corvids (including crows), especially in urban and other anthropogenic settings, a negative perception of this ...

Elephant cognition in primate perspective [PDF]

open access: yes, 2009
On many of the staple measures of comparative psychology, elephants show no obvious differences from other mammals, such as primates: discrimination learning, memory, spontaneous tool use, etc. However, a range of more naturalistic measures have recently

Evaluation of drones as a tool for multi‐species nest surveys on linear rights‐of‐way

open access: yesWildlife Society Bulletin, Volume 50, Issue 1, March 2026.
This paper examines the use of drones with infrared cameras as a tool in the detection of bird nests on linear rights‐of‐way, in comparison to standard ground‐based nest surveys. Abstract The varying application of drone use in wildlife research has expanded in recent years. With the ability to utilize a variety of different sensors (e.g., infrared [IR]

Integrating Lab‐ and Field‐Based Approaches to Decipher Individuals' Response to Anthropogenic Change

open access: yesEcology Letters, Volume 29, Issue 3, March 2026.
We integrate laboratory assays and GPS tracking to examine consistent risk‐taking behaviour in Fan‐tailed Ravens (Corvus rhipidurus) inhabiting Israel's Dead Sea coastline. Individual risk profiles were consistent across lab and field contexts, with risk‐prone birds remaining near tourist sites and risk‐averse birds ranging farther into natural ...
