Population estimates of shorebirds on the Atlantic Coast of southern South America generated from large-scale, simultaneous, volunteer-led surveys

Journal of Field Ornithology
Population abundance and trend estimates are crucial to science, management, and conservation. Shorebirds, which are abundant in many coastal habitats and play important roles in coastal ecosystems, are facing some of the most dramatic population ...

Taxonomic Status and Phylogenetic Relationship of the Charadriidae Family Based on Complete Mitogenomes

Current Genomics, 2023
Background: The Charadriiformes provide a good source for researching evolution owing to their diverse distribution, behavior, morphology, and ecology. However, in the Charadrii, family-level relationships remain understudied, and the monophyly of Charadriidae is also a subject of controversy.

Extreme site fidelity in long‐distance migratory shorebirds in Australia and potential implications for conservation

Conservation Biology, EarlyView.
Abstract Site fidelity is the tendency for animals to repeatedly return to the same locations, either within or between years. Site fidelity enables animals to utilize knowledge of previously visited locations, including assessments of seasonal variations in health and mortality risks (e.g., predation), resource availability, and social benefits such ...

Ticks on birds caught on the campus of the Federal Rural University of Rio de Janeiro, Brazil Carrapatos em aves capturadas no campus da Universidade Federal Rural do Rio de Janeiro, Brasil

Revista Brasileira de Parasitologia Veterinária, 2012
The prevalence of parasitic infections, particularly those caused by ectoparasites, may influence the biology and ecology of wild birds. The aim of this study was to investigate occurrences and identify the species of ticks collected from wild birds ...

Describing Diet of Imperiled Sierra Nevada Red Foxes and a Carnivoran Competitor Using DNA Metabarcoding. [PDF]

Ecol Evol
Montane red foxes (Vulpes vulpes ssp.) native to western North America are of broad conservation interest, but their ecology is poorly understood due to their rarity. We examined the diet of the Sierra Nevada red fox (V. v. necator) in an unstudied portion of their range in Oregon, USA, then evaluated dietary overlap between red fox and coyote (Canis ...

Relationships between chick vocalizations and parental absence in Kentish Plovers

Ibis, EarlyView.
Chick calls within bird species vary greatly, often in relation to whether parents are present. We studied chick calls in a nidifugous shorebird, the Kentish Plover Anarhynchus alexandrinus, in three circumstances—(1) on the nest with parental presence; (2) on the nest with parental absence; and (3) out‐of‐nest with human observer presence—and ...

Global analysis of annual survival among shorebirds reveals a negative effect of migration distance and a decline in recent decades

Oikos, Volume 2026, Issue 7, July 2026.
Annual survival is a key demographic parameter driving population trends in wildlife populations. However, despite numerous species‐specific or regional studies, global reviews of the factors affecting the survival of declining taxa remain scarce. Here, we investigated annual survival of fledged immature and adult shorebirds, a globally‐distributed and
