Wildlife Biology, EarlyView.Predator control is a widely used management tool worldwide to reduce the impact of opportunistic predatory species, but in some contexts where predators are controlled to reduce negative impacts on game species, there are concerns about the selectivity and efficiency.

Preliminary observations of tool-processing behaviour in Hawaiian crows Corvus hawaiiensis
Communicative & Integrative Biology, 2018 Very few animal species habitually make and use foraging tools. We recently discovered that the Hawaiian crow is a highly skilled, natural tool user. Most captive adults in our experiment spontaneously used sticks to access out-of-reach food from a range

Integrative Zoology, EarlyView.Low overall haemosporidian occurrence (3.4%; 13/383). Unexpected high lineage diversity (10 new host–parasite interactions). Novel Leucocytozoon lineage (GYPBAR01) in all European vultures except the griffon vulture. Plasmodium relictum (lineage SGS1) in adult red kites.

Tree Squirrels Selectively Disperse High‐Quality Acorns Away From Tree Trunks
Integrative Zoology, EarlyView.Acorn quality and squirrel feeding behavior significantly structured spatial dispersal patterns of two Californian oak species. Non‐infested acorns were preferentially selected for embryo excision and dispersed farther than infested ones. Acorns were fully consumed near tree trunks, signaling rapid feeding in safe refuges, whereas non‐eaten, partially ...

Assessing Spatiotemporal Side Effects of Diversionary Feeding on Mesopredators
Animal Conservation, EarlyView.We tested whether diversionary feeding alters the space use, aggregation, or activity patterns of mesopredators using a treatment‐control design with camera traps. Although both species frequently used feeding stations, diversionary feeding did not significantly affect their spatial distribution, aggregation, or temporal behaviour.

Ethology, EarlyView.Corpses are repositories of information about the cause of death. The distress of the bereaved acts as an honest signal drawing conspecifics to the body, enabling them to learn quickly about the death, adapt their behaviour, and spread knowledge of threats across multiple social levels.

Corvid meteoroids and a Giordano Bruno ray are genetically related [PDF]
, 1993 Both Corvid meteoroids and the Giordano Bruno (GB) crater are products of recent events. On June 25, or 26, 1178, Corvid meteoroids and a portion of GB ejecta were at the same place in the Solar System and moved in the same direction (right ascension ...

Individual exploratory responses are not repeatable across time or context for four species of food-storing corvid. [PDF]
, 2020 Exploration is among one of the most studied of animal personality traits (i.e., individual-level behavioural responses repeatable across time and contexts). However, not all species show clear evidence of this personality trait, and this is particularly

Learning from the Ravens: Worship and Wisdom with the Birds in the Hebrew Bible
ZygonThis article investigates how animals in general and ravens in particular function as exemplary worshipers of God. As such, they exhibit certain kinds of wisdom that humans are invited to emulate.
