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

WATERBIRDS BIODIVERSITY AND ATTENDANCE IN Rhizophora Sp. MANGROVE STANDS OF VARYING PLANTING AGES [PDF]
, 2015 Many species of waterbirds depend on wetland sites and related with variated habitats based on the maturity of ecosystems. The objective of this study was to determine the attendance and biodiversity of waterbirds in Rhizophora sp.

Accounting for animal movement during aerial imaging surveys
Remote Sensing in Ecology and Conservation, EarlyView.Animals are not stationary during aerial surveys; if their movements are related to the movement of the aerial platform, then bias can be introduced into subsequent population count estimates. We sought to establish a framework for assessing the impacts of animal movement on count error and platform bias by comparing aggregated counts and relative ...

Remote Sensing in Ecology and Conservation, EarlyView.This study evaluates the performances of synchronous aerial visible (VIS) and thermal infrared (TIR) imagery for detecting great blue heron (Ardea herodias) nests and individuals using a YOLO11n model. VIS and TIR images were automatically aligned using deep learning, and both early and late fusion approaches were tested.

Response of Waterbirds to Salt Pond Enhancements and Island Creation in the San Francisco Bay [PDF]
, 2013 Historically, San Francisco Bay supported the largest salt pond complex on the Pacific coast of North America, and these areas have been used by large numbers of migrating and wintering waterbirds for more than a century.

Wildlife Biology, EarlyView.Wildlife research has benefitted from the development of new methods that allow data to be collected remotely, with less disturbance to focal animals. The proliferation of livestreaming webcams, for example, those used by nature reserves for public engagement purposes, have offered new possibilities for the study of wildlife behaviour.

Using programmable infusion pump in avian species – a validation methodology in geese
Wildlife Biology, EarlyView.Wildlife face anthropogenic and natural stressors that affect their physiology and behaviour. The activity of the hypothalamic–pituitary–adrenal axis and glucocorticoid (GC) production is intrinsically linked with energy regulation and environmental stressors.
