Pedogeochemical Anomalies in Surroundings of Great Cormorant Colony (Case Study in Lithuania)
E3S Web of Conferences, 2013 The area where the colony of great cormorants in Curonian Spit (Lithuania) prospers from 1989 is the study object of “Koreko” project. Based on geochemical results of 90 samples of topsoil from 6 zones which differ according to the influence of the great

The influence of rivers on seabird foraging ecology
Biological Reviews, EarlyView.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 ...

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.

International Journal of Osteoarchaeology, EarlyView.ABSTRACT The golden eagle (Aquila chrysaetos) nests in rock cavities where it accumulates prey bone remains during the breeding season. Because nests can be reoccupied from year to year, these faunal elements can form remarkable bone accumulations and, in the sub‐fossil record, be mixed with assemblages derived from human or other predator activities ...

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

Predator telemetry informs temporal and spatial overlap with stocked salmonids in Lake Huron
Animal Biotelemetry, 2023 Double-Crested Cormorants (Phalacrocorax auratus), Walleyes (Sander vitreus), and Lake Trout (Salvelinus namaycush) are migratory predators that undergo extensive movements in Lake Huron. Stocking of juvenile salmonid fish (Oncorhynchus and Salmo sp.) is

Ibis, EarlyView.Seabirds serve as key indicators of marine environmental changes, with adult survival being a critical parameter for assessing population health. Iceland hosts some of the largest seabird populations in the North Atlantic, making it a valuable location for studying long‐term trends in seabird demographics.
