Effect of Morphology and Spatial Distribution of Males on Vocal Identity in a Non‐Learning African Wood Dove

open access: yesIntegrative Zoology, EarlyView.
Emerald‐spotted Wood‐Dove songs show strong individual vocal signatures. Morphology explains little acoustic variation. Acoustic divergence increases with geographic distance between males, while local neighbor density does not influence vocal distinctiveness.

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

open access: yesConservation 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 ...

The pectoralis muscle orientation as an indicator of the modes of wing‐propelled locomotion in birds

open access: yesJournal of Anatomy, EarlyView.
The pectoralis orientation of birds was consistent with the orientation of the aerodynamic force acting on the wing, varying by wing‐propelled locomotion (WPL) mode. The skeletal morphology unique to each WPL mode, related to the origin/insertion of the pectoralis, may be associated with these functional demands of pectoralis orientation.

The link between colorfulness and extinction risk across the world's passerine birds

open access: yesConservation Biology, Volume 40, Issue 5, October 2026.
Abstract Many of the functional traits that mediate extinction risk across the range of biodiversity relate indirectly to a species’ ability to persist in a changing world, yet certain traits such as coloration directly affect human interactions with wildlife.

Variation in parrot jaw musculature

open access: yesThe Anatomical Record, Volume 309, Issue 9, Page 2519-2533, September 2026.
Interspecific morphological differences in some superficial jaw muscles of parrots. Abstract Psittaciformes, the order encompassing parrots and their relatives, are highly diverse and generally known for having a strong beaks used for multiple behaviors. The muscles related to the masticatory apparatus should reflect this functional complexity; however,

The disruption of seed dispersal networks: disentangling the effects of habitat loss and fragmentation

open access: yesOikos, Volume 2026, Issue 9, September 2026.
Seed dispersal by frugivores is a central process linking plant reproduction, animal foraging, population persistence, and ecosystem resilience. Currently, the spatial template sustaining these interactions is rapidly reconfigured by habitat loss and fragmentation promoted by human activity.

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.

Haemoproteosis and avian malaria in Columbidae and Corvidae from Iran

open access: yesVeterinary Medicine and Science, 2021
Avian malaria (Plasmodium) and related genera (Haemoproteus and Leucocytozoon) are diverse and widespread parasites. Despite the extent of knowledge on avian haemosporidian parasites, information about domestic and wild bird's blood parasites is overall ...

Lures do not increase box‐trapping success of an endangered felid in South Texas

open access: yesWildlife Society Bulletin, Volume 50, Issue 2, June 2026.
We used a randomized design and linear regression to assess whether visual (compact disc [CD] and ribbon), and olfactory (musk and ocelot urine) lures would increase capture success of three mesocarnivores (ocelots [Leopardus pardalis], bobcats [Lynx rufus], and coyotes [Canis latrans]) with box traps baited with a live bird from December 2023 to April
