Early Duplication of a Single MHC IIB Locus Prior to the Passerine Radiations. [PDF]

, 2016
A key characteristic of MHC genes is the persistence of allelic lineages over macroevolutionary periods, often through multiple speciation events. This phenomenon, known as trans-species polymorphism (TSP), is well documented in several major taxonomic ...

Threat-sensitive anti-predator defence in precocial wader, the northern lapwing Vanellus vanellus [PDF]

, 2016
Birds exhibit various forms of anti-predator behaviours to avoid reproductive failure, with mobbing—observation, approach and usually harassment of a predator—being one of the most commonly observed. Here, we investigate patterns of temporal variation in

Social learning about dangerous people by wild jackdaws [PDF]

Royal Society Open Science, 2019
For animals that live alongside humans, people can present both an opportunity and a threat. Previous studies have shown that several species can learn to discriminate between individual people and assess risk based on prior experience.

Wild jackdaws are wary of objects that violate expectations of animacy [PDF]

Royal Society Open Science, 2018
Nature is composed of self-propelled, animate agents and inanimate objects. Laboratory studies have shown that human infants and a few species discriminate between animate and inanimate objects.

Individual identity in songbirds: signal representations and metric learning for locating the information in complex corvid calls [PDF]

, 2016
Bird calls range from simple tones to rich dynamic multi-harmonic structures. The more complex calls are very poorly understood at present, such as those of the scientifically important corvid family (jackdaws, crows, ravens, etc.).

Human food subsidies drive individual specialization and intrapopulation dietary differences in a generalist predator

Ecosphere, 2022
Generalist species can exhibit individual specialization (IS), where individuals adopt specialized foraging behaviors not attributable to age, sex, or social dominance.
