Risk posed by the HPAI virus H5N1, Eurasian lineage goose/Guangdong clade 2.3.4.4b. genotype B3.13, currently circulating in the US

open access: yesEFSA Journal, Volume 23, Issue 7, July 2025.
Abstract The emergence of highly pathogenic avian influenza (HPAI) A(H5N1), clade 2.3.4.4b, genotype B3.13 in U.S. dairy cattle marks a significant shift in the virus' host range and epidemiological profile. Infected cattle typically exhibit mild clinical signs, such as reduced milk production, mastitis and fever, with morbidity generally below 20% and

Evaluating environmental drivers and synchrony of Arctic shorebird demographic rates to inform conservation management

open access: yesEcological Applications, Volume 35, Issue 4, June 2025.
Abstract Many Arctic‐breeding shorebirds are assumed to be declining, yet obtaining reliable estimates of species' demographic rates and trends is difficult because of challenges collecting data in remote breeding regions and throughout the annual cycle.

MODELING THE EFFECTS OF PREDATOR EXCLOSURES ON A WESTERN SNOWY PLOVER POPULATION

open access: yesNatural Resource Modeling, 2012
Abstract In Humboldt County, California, nest exclosures were used between 2001 and 2006 to reduce the predation of eggs aiding in the recovery of a threatened population segment of western snowy plovers (Charadrius nivosus). Due to a sudden increase in adult mortality in 2006, field biologists abandoned the use of nest exclosures. This paper describes

Common Raven Impacts on Nesting Western Snowy Plovers: Integrating Management to Facilitate Species Recovery

open access: yes, 2021
The U.S. Pacific coast population of the western snowy plover (Charadrius nivosus nivosus; plover) has declined due to loss and degradation of coastal habitats, predation, and anthropogenic disturbance. The U.S. Fish and Wildlife Service listed the subspecies in 1993 as threatened under the Endangered Species Act due to the population declines and ...

Commons are cared for: Coexistence between humans and wild birds on the island of Kihnu, Estonia

open access: yesPeople and Nature, Volume 7, Issue 5, Page 960-973, May 2025.
Abstract Local knowledge is an essential dimension of humanity's relationship with the environment. Investigating the interdependence between humans and wild birds holds value in fostering a mutually beneficial relationship with avian populations. Gathering bird eggs is a significant practice for Kihnu islanders in Estonia.

Common Raven Impacts on the Productivity of a Small Breeding Population of Snowy Plovers [PDF]

open access: yes, 2021
Common ravens (ravens; Corvus corax), an adaptable, synanthropic generalist, have thrived coincident with increasing human landscape modifications and fragmentation, consequently affecting their prey, which are often sensitive native and protected ...

Keystone effects of prairie dogs (Cynomys spp.) on grassland birds: Current knowledge and future directions

open access: yesConservation Science and Practice, Volume 7, Issue 4, April 2025.
This article reviews the literature on how prairie dogs as keystone species affect grassland birds, an imperiled avian community. We tested hypotheses and synthesized conclusions from the literature, and then we identified key knowledge gaps to be filled with future work.

The Influence of Migration Timing and Local Conditions on Reproductive Timing in Arctic‐Breeding Birds

open access: yesEcology and Evolution, Volume 15, Issue 1, January 2025.
We used tracking and breeding data from 248 individuals of 8 species and subspecies of Arctic‐breeding shorebirds to estimate how the timing of nest initiation is related to local conditions like snowmelt phenology versus prior conditions, measured by the timing and speed of migration.
