Underestimation of avian diversity in the Tumbesian hotspot: Sampling gaps and conservation challenges

Conservation Science and Practice, EarlyView.
This study provides the first comprehensive reassessment of avian diversity in the Tumbesian region in over 30 years, documenting 931 species and identifying significant sampling gaps driven by geographic accessibility. We reveal a critical misalignment between biodiversity value and current protection coverage, particularly in humid forests which ...

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

Ibis, 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.

Relationship between carina size and sternum morphology in birds reflects physical constraints of body size and flight style

Journal of Anatomy, EarlyView.
Sternum morphology varies among birds and is a function of body mass and order. The area of the sternum is inversely related to the area of the keel suggesting that the increase in bone mass associated with a large keel has been mitigated by a reduction in bone mass of the sternum.

Rapid responses of marsh birds to large‐scale tidal wetland restoration in California's Sacramento–San Joaquin Delta

Restoration Ecology, EarlyView.
Abstract Introduction Tidal wetland restoration is widely used to recover ecosystem function in modified estuaries, yet uncertainty remains about how quickly wildlife communities respond. Early trajectories are central to evaluating restoration success, guiding adaptive management, and building ecosystem resilience in engineered landscapes. Marsh birds

Sexually dichromatic hybrids between two monochromatic duck species, the Chiloé wigeon and the Philippine duck

Ecology and Evolution, 2021
Captive bird hybrids can provide important data on certain traits, such as hybrid viability and fertility. In this paper, we describe four hybrids between the Chiloé wigeon (Anas sibilatrix) and the Philippine duck (Anas luzonica).

Re‐evaluation of a soft crested Edmontosaurin, with implications for hadrosaurid life appearance and diversity

The Anatomical Record, Volume 309, Issue 10, Page 2636-2655, October 2026.
Abstract Hadrosaurid dinosaurs are generally regarded as “crested” or “non‐crested” depending on the presence or absence of a bony cranial crest. At least one supposedly “non‐crested” hadrosaur is known to have possessed a soft tissue cranial crest (or comb), based on an exceptionally preserved “mummified” specimen. Here we redescribe this specimen and

Courtship display behavior influences tail myology in Centrocercus minimus (Gunnison sage‐grouse)

Journal of Anatomy, Volume 249, Issue 4, Page 705-713, October 2026.
Courtship displays among birds are widespread, particularly those which incorporate raised tail feathers for extended periods of time. The Gunnison sage‐grouse (Centrocercus minimus) is such a species. When we compared the tail muscles of the sage‐grouse to birds which do not engage in erected tail fan postures, both morphology proportional mass ...

Migration routes and key stopovers of Anser fabalis fabalis (Anseriformes): critical protection gaps

Nature Conservation Research: Заповедная наука
The population of Anser fabalis fabalis wintering in Europe have shown decline in recent decades. At the same time, the population dynamic of most migratory birds largely depends on the quality of migratory stopover sites, which are necessary to ...

A hitherto unrecorded sighting of the Common Pochard Aythya ferina (Linnaeus, 1758) (Aves: Anseriformes: Anatidae) in Vedanthangal Bird Sanctuary, Tamil Nadu, India

Journal of Threatened Taxa, 2014
The Common Pochard Aythya ferina (Linnaeus, 1758) (Aves: Anseriformes: Anatidae) is recorded for the first time in Vedanthangal Bird Sanctuary, Tamil Nadu, India.

Causes of interspecific variation in avian migration distance

Ecology, Volume 107, Issue 9, September 2026.
Abstract Migration is an awe‐inspiring behavior employed by a diverse suite of taxa throughout the animal kingdom. Avian migration is arguably the most well‐known animal behavior and birds vary widely in how far they migrate, but the ecological mechanisms underlying interspecific variation in migration distance remain unclear.
