Two Capture Techniques for American White Pelicans and Great Blue Herons

Colonial Waterbirds, 1998
-We describe two techniques for capturing American White Pelicans (Pelecanw erythmhynchos), Great Blue Herons (Ardea harodias), and other large wading birds in aquatic habitats. One technique involved using #3 padded jaw leghold traps modified by replacing both factory coil springs with weaker #1.5 coil springs, to reduce the closing force of the jaws,

Counting cases, conserving species: addressing highly pathogenic avian influenza in wildlife

Biological Reviews, EarlyView.
ABSTRACT Highly pathogenic avian influenza (HPAI) has become a critical threat to wildlife, shifting from a seasonal epizootic to a persistent, year‐round panzootic with global consequences. Here, we summarise the origin, evolutionary mechanisms, and expanding host range of the current H5N1 virus (clade 2.3.4.4b) and assess its impact on wildlife. Over

Big Bird: A global dataset of birds in drone imagery annotated to species level

Remote Sensing in Ecology and Conservation, EarlyView.
Drones are a valuable tool for surveying birds, but manually detecting and identifying birds in drone images is costly. We assembled a diverse dataset of 23 865 images of birds captured with 21 different drones across 11 countries. We labelled 4824 of these images, detailing the location, species, posture category, age category, and sex of 49 990 birds

Breeding seabirds at Dassen Island, South Africa: chances of surviving great white pelican predation [PDF]

Endangered Species Research, 2010
Seabird predation by great white pelicans Pelecanus onocrotalus is an unusual phenom- enon that has become increasingly frequent in the Western Cape, South Africa. We report the scale of pelican predation and its impact on the breeding success of 5 seabird species monitored at Dassen Island in 2006.

Waterbird zoogeochemical effects shape wetland nutrient dynamics and algal communities in Laurentian Great Lakes coastal freshwater wetlands

Journal of Animal Ecology, EarlyView.
Distinct waterbird species influence nutrient cycling through guano contributions in Great Lakes coastal wetlands. Waterbird‐derived nutrients favour distinct algal communities and wetland sediments rapidly remove waterbird nutrients via biogeochemical processes.

The influence of rivers on seabird foraging ecology

Biological Reviews, Volume 101, Issue 4, Page 1704-1734, August 2026.
ABSTRACT Rivers act as vital arteries to the world's oceans, delivering fresh water and nutrients that sustain marine ecosystems. Globally, river flow increasingly is being altered by climate change and anthropogenic pressures; yet the significance of rivers to predatory marine species, such as seabirds, and the extent to which river‐related changes ...

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

Biological Reviews, Volume 101, Issue 3, Page 1406-1462, June 2026.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

Monitoring the Great White Pelican elecanus onocotalus Linnaeus, 1 breeding population using drones in 1 the Danube Delta Romania

Scientific Annals of the Danube Delta Institute, 2017
The Danube Delta colony of the Great White Pelican (Peea a) was evaluated in 2016 at 17,000 pairs, with a minimum of 15,000 and a maximum of 19,000 pairs. We used unmanned aerial vehicle UAV) technology to count the number of nesting birds in the colony.

When machines invent: How AI shapes patent litigation outcomes

American Business Law Journal, Volume 63, Issue 2, Page 177-187, Summer 2026.
Abstract Artificial intelligence (AI) is no longer merely a tool of invention. It has become an inventor. As AI systems increasingly contribute to the design and discovery of new technologies, their involvement raises novel challenges for patent law. This essay presents the first empirical test of whether jurors systematically perceive alleged patent ...

Rediscovery and redescription of clinostomid trematodes from Pelecanus onocrotalus

Parasitology
This study reports the first rediscovery and redescription of Euclinostomum lauroi in more than 40 years, based on an adult specimen recovered from the oesophagus of a great white pelican (Pelecanus onocrotalus) in Lake Tana, Ethiopia.
