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

open access: yesRemote 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

Ecological connection between fish preference in the diet of Siberian cranes and their incubation period in tundra zone [PDF]

open access: yes, 2012
We researched the ecology of the third rarest crane species, Siberian crane, which breeds in northern-eastern Siberian tundra. Nesting in places near great lakes, this crane appears to be an indicator of the global warming processes that affect lake ...

Phenology of migrating game birds in Italy based on citizen science data

open access: yesWildlife Biology, EarlyView.
Studying the timing of the seasonal movements of migratory birds, known as migration phenology, is crucial for managing and conserving migratory bird populations. This is particularly important for migratory game bird populations in Europe because, according to the EU, migratory birds should not be hunted during their breeding season or during return ...

Response of Bird Populations to Long-term Changes in Local Vegetation and Regional Forest Cover [PDF]

open access: yes, 2016
We analyzed data from a woodland site for a 59-year period to determine whether changes in bird populations are related to changes in the diversity and relative abundance of woody plant species even when vegetation structure, degree of forest ...

Nesting ecology of an ice‐associated seabird, Kittlitz's murrelet, at the northern edge of its range

open access: yesWildlife Society Bulletin, EarlyView.
We studied the Kittlitz's murrelet, an ice‐associated seabird of conservation concern, at the northern edge of its range. Over a 2‐year period, we estimated nest density and success at 2 sites, captured and telemetered nesting murrelets, and tested the use of a thermal camera to improve nest detection.
