Steep declines of colonial wading birds in northeastern North America's largest breeding population

open access: yesConservation Science and Practice, EarlyView.
This study analyzed 22 years of complete nest census data for colonial wading birds in New York–New Jersey Harbor, the largest breeding population in the northeastern United States. Over this period, the total wading bird population decreased by 27%, a rate exceeding average long‐term declines across North American birds.

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.

Effects of researcher disturbance on Double-crested Cormorant nest survival

open access: yesJournal of Field Ornithology
Demographic data on avian species are critically important for conservation and management. Research on avian demography often requires some level of human disturbance at nest sites.

Swimming modes affect dive durations in diving birds

open access: yesJournal of Avian Biology, Volume 2026, Issue 2, March 2026.
Dive duration and body mass are positively correlated across air‐breathing vertebrate species, but other factors affecting dive duration are inadequately studied. Here, we examined the effect of a previously overlooked factor, swimming mode, using phylogenetically informed statistics with data on the diving capabilities of 53 species of avian divers ...

Behavioral Evidence of Predator–Predator Commensalism: Cobia Track and Feed on Prey Disturbed by Southern Stingrays

open access: yesEthology, Volume 132, Issue 3, Page 225-234, March 2026.
We documented a novel predator–predator commensal foraging interaction between cobia (Rachycentron canadum) and a southern stingray (Hypanus americanus) in a shallow coastal habitat of Biscayne Bay, Florida. Using drone‐based observations, we recorded a 7‐min sequence in which a cobia closely tracked the stingray's movements and fed on prey disturbed ...

Avian influenza overview December 2025–February 2026

open access: yesEFSA Journal, Volume 24, Issue 3, March 2026.
Abstract Between 29 November 2025 and 27 February 2026, 2514 highly pathogenic avian influenza (HPAI) A(H5) virus detections were reported in domestic (406) and wild (2108) birds in 32 countries in Europe. Albeit still at high levels after the peak was reached at the beginning of the current reporting period, the weekly number of detections has since ...

Climate Change, Local Harvests and Marine Contamination: A Perspective on Cetacean Populations and Coastal Whaling Communities

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 2, February 2026.
ABSTRACT Cetaceans are indicators of ocean health, influence marine ecosystem dynamics and hold socio‐economic importance for coastal whaling communities. Yet whale–whaler relationships remain poorly understood and are increasingly compromised under the triple planetary crisis of climate change, biodiversity loss and pollution. Here, we briefly outline

Marking power lines to reduce avian collisions near the Audubon National Wildlife Refuge, North Dakota

open access: yesWildlife Society Bulletin, 2013
Overhead power lines can pose collision risks to birds. Risks may be mitigated through marking lines with high‐visibility devices, but the effectiveness of line marking remains unclear.
