The Role of Birds of the Family Corvidae in Transmitting Sarcocystis Protozoan Parasites

open access: yesAnimals, 2021
Members of the family Corvidae are ecologically flexible omnivorous birds, particularly adaptive to urban habitats, and living in proximity to humans; these birds may serve as definitive hosts (DH) for Sarcocystis spp., but research about this is lacking.

Selectivity and efficiency of predator control methods: a case study from a Mediterranean hunting ground

open access: yesWildlife 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.

Testing social learning of anti-predator responses in juvenile jackdaws: the importance of accounting for levels of agitation [PDF]

open access: yesRoyal Society Open Science, 2018
Social learning is often assumed to help young animals respond appropriately to potential threats in the environment. We brought wild, juvenile jackdaws briefly into captivity to test whether short exposures to conspecific vocalizations are sufficient to

Unraveling Occurrence Patterns and Diversity of Avian Malaria Parasites in Iberian Obligate and Facultative Scavenger Birds

open access: yesIntegrative 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

open access: yesIntegrative 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

open access: yesAnimal 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.

Corpses as Repositories of Information and Funerals as Information Centres: Why Natural Selection Favours the Bereaved

open access: yesEthology, 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.

Effects of Land Use Intensification on Avian Predator Assemblages: A Comparison of Landscapes with Different Histories in Northern Europe

open access: yesDiversity, 2019
Land use and landcover change alter the ability of habitat networks to maintain viable species populations. While their effects on the quality, amount and patterns of landcover patches are commonly studied, how they affect ecological processes, such as ...

New Caledonian Crows and Hidden Causal Agents Revisited

open access: yesAnimal Behavior and Cognition, 2021
A previous experiment suggested that New Caledonian crows (Corvus moneduloides; henceforth NCCs) can reason about hidden causal agents (Taylor et al., 2012).

A systematic review and meta‐analysis of variation in nest predation of ground‐nesting birds

open access: yesIbis, EarlyView.
Predation and communities of predators of ground‐nesting bird nests and fledglings have been studied across multiple groups of ground‐nesting birds, such as waders, waterbirds, gamebirds and passerines, and habitats, but differences and similarities between groups are less studied.
