Predator‐guild‐specific parental responses mitigate higher predation risk on ground nests close to forest patches in a mosaic landscape

Journal of Animal Ecology, EarlyView.
Predation increases close to habitat edges, but how animals cope with local predation variations remained poorly studied. In a mosaic landscape, lapwings were compensating for increased nest predation close to forests. They acted more aggressively towards an avian predator when nesting close to trees, but comparatively tamer against a mammal.

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

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.

Heterogeneous structure in mixed-species corvid flocks in flight [PDF]

, 2014
Flocks of birds in flight represent a striking example of collective behaviour. Models of self-organization suggest that repeated interactions among individuals following simple rules can generate the complex patterns and coordinated movements exhibited ...

Managing the Threat of Subsidized Predators for a Threatened Shorebird

Animal Conservation, EarlyView.
Subsidized predators—native predators that have become more common due to human activities—challenge the persistence of many at‐risk prey species and require creative solutions beyond lethal predator control. In an 8‐year study, we placed small wire cages over western snowy plover nests that allow passage of plovers, but not their predators, and ...

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

Studia 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 ...

Phenotypic plasticity in nest departure calls: Weighing costs and benefits [PDF]

, 2014
In birds, male song has been extensively studied, but female vocalizations have received little attention. Females of several North American species produce a unique vocalization, the nest departure call (NDC), upon leaving nests.

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.
