Gastrointestinal Helminths of Magpies (Pica), Rooks (Corvus Frugilegus) and Carrion Crows (Corvus Corone) in Mazandaran Province, North of Iran [PDF]

open access: yesIranian Journal of Parasitology, 2011
Background: Corvidae is a cosmopolitan family of oscine birds including crows, rooks, mag­pies, jays, chough, and ravens. These birds are migratory species, especially in the shortage of foods, so they can act like vectors for a wide range of ...

Intraspecific variability in feather moult extent declines under both low and high constraints

open access: yesFunctional Ecology, Volume 40, Issue 8, Page 2350-2362, August 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Intraspecific trait variability (ITV) is a fundamental feature of biological populations and the raw material upon which natural selection acts, yet its drivers remain poorly understood.

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.

Benefit or ecological trap? Monitoring the effects of small clear‐cuts on capercaillie Tetrao urogallus and its mammalian predators

open access: yesWildlife Biology, Volume 2026, Issue 4, July 2026.
The shift to ‘close to nature forestry' as the dominating forestry regime in western‐European forests has resulted in increasing timber volume and denser forests with negative effects on photophilic species. Hence, there is an increasing focus on active habitat management measures to support these species.

Dissemination and genetic diversity of chlamydial agents in Polish wildfowl: Isolation and molecular characterisation of avian Chlamydia abortus strains.

open access: yesPLoS ONE, 2017
Wild birds are considered as a reservoir for avian chlamydiosis posing a potential infectious threat to domestic poultry and humans. Analysis of 894 cloacal or fecal swabs from free-living birds in Poland revealed an overall Chlamydiaceae prevalence of ...

Whole System Ecohydrological Change Following Natural Flood Management and a Five‐Year Beaver Reintroduction Trial

open access: yesEcohydrology, Volume 19, Issue 4, June 2026.
ABSTRACT Once‐common beavers have been absent from the British landscape for centuries, but wild beaver populations have returned in recent years as part of reintroduction schemes, including releases into monitored enclosures. In North Yorkshire, such a release of Eurasian beavers took place in 2019.

Bir grup Pica pica’da (Passeriformes: Corvidae) posmortem bulgular [PDF]

open access: yes, 2019
Common magpies (Corvidae: Pica pica) distribute through rural and urban areas of Turkey. Because of their distribution in urbanised regions, magpies may have some potential infectious agents which may relate to domestic animals and humans. In this study,

Sex-specific effects of cooperative breeding and colonial nesting on prosociality in corvids

open access: yeseLife, 2020
The investigation of prosocial behavior is of particular interest from an evolutionary perspective. Comparisons of prosociality across non-human animal species have, however, so far largely focused on primates, and their interpretation is hampered by the

Spatial distribution of acoustic traits in bird assemblages along regional bioclimatic gradients

open access: yesEcography, Volume 2026, Issue 6, June 2026.
Environmental variation shapes acoustic interactions among birds, creating spatial structures in the sonic signature of local species assemblages. Exploring these patterns at regional scales can reveal processes that segregate acoustic strategies along environmental gradients.

Functional diversity in agricultural landscapes: evidence of long‐term clustering and multi‐scale effects of land use on avian communities

open access: yesOikos, Volume 2026, Issue 6, June 2026.
Functional diversity (FD) is an essential community property connecting biodiversity, ecosystem functioning, and conservation objectives. In agricultural landscapes, avian communities, which play key functional roles, are facing large‐scale biodiversity erosion, largely due to land‐use changes.
