Swimming modes affect dive durations in diving birds

Journal 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 ...

Capture and telemetry techniques for double-crested cormorants (Phalacrocorax auritus) [PDF]

, 2000
Double-crested Cormorants (Phalacrocorax auritus) often roost in cypress oxbows and nest on islands making their capture for research studies difficult.

Double‐crested cormorant distribution on catfish aquaculture in the Yazoo River Basin of Mississippi

Wildlife Society Bulletin, 2012
Estimating the catfish aquaculture production losses that can be attributed to double‐crested cormorants (Phalacrocorax auritus) has proved problematic because knowledge of the distribution of cormorants on catfish aquaculture is lacking.

Monitoring faunal responses to biodegradable oyster reef restoration materials with camera traps in a subtropical estuary

Restoration Ecology, Volume 33, Issue 8, November 2025.
Oyster reef restoration has become increasingly crucial due to global population declines. Intertidal oyster reefs provide essential foraging and loafing (resting) grounds to estuarine fauna. To reduce plastic pollution from traditional materials, biodegradable restoration materials have been introduced and are shown to support oyster recruitment ...

CT scan data of wild double-crested cormorant, Phalacrocorax auritus OUVC 10645

, 2016
This zip file contains DICOM images from an x-ray microcomputed tomography (µCT) scan of an injected Phalacrocorax auritus (OUVC 10645). The arteries were injected with a latex and barium solution and scanned on a GE eXplore Locus in vivo Small Animal ...

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

Wildlife 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.

Marine Bird Bycatch in Alaska Salmon Gillnet Fisheries

Fisheries Management and Ecology, Volume 32, Issue 5, Page 366-387, October 2025.
ABSTRACT Incidental catch in gillnet fisheries has a substantial conservation impact on marine diving birds. We synthesized available marine bird bycatch data from Alaska salmon gillnet fisheries to estimate standardized bycatch rates, model factors influencing bycatch rates, and estimate total bycatch.

Bone Mineral Density of Willow Ptarmigan (Lagopus lagopus) as a Potential Taphonomic Factor in Skeletal Part Attrition

International Journal of Osteoarchaeology, Volume 35, Issue 5, Page 284-294, September/October 2025.
ABSTRACT Agents of taphonomy can bias skeletal parts and the frequency of bones in archaeological sites. An important factor to consider is the possible effect of bone density‐mediated attrition on archaeornithological assemblages. We scanned willow ptarmigan (Lagopus lagopus) specimens using a Lunar iDXA and an enCcore small animal body add‐on to ...

Sinoatrial Contracaeciasis in Johnny Darters (Etheostoma nigrum) and Plains Topminnow (Fundulus sciadicus) From the South Platte Drainage, Colorado

Aquaculture, Fish and Fisheries, Volume 5, Issue 4, August 2025.
ABSTRACT Intra‐sinoatrial nematodes were incidentally recognized in wild‐caught Colorado Johnny Darters (Etheostoma nigrum, JD) in 2020–2021 and in Colorado Plains Topminnow (Fundulus sciadicus, PTM) in 2023‐2024. PTM and JD were evaluated histologically.

Climate‐related drivers of migratory bird health in the south‐central USA

Biological Reviews, Volume 100, Issue 3, Page 1272-1293, June 2025.
ABSTRACT Migratory birds are species of concern that play important ecological roles while also supporting recreational opportunities for the hunting and birdwatching public. Direct and indirect effects of climate variability, extremes, and change on migratory bird health manifest at the individual, population, species, and community levels.
