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

Habitat modification in relation to coastal reclamation and its impacts on waterbirds along China's coast

Global Ecology and Conservation, 2019
The eastern coast of China provides a network of Important Bird Areas (IBAs) as feeding and breeding habitats, as well as migratory corridors for a large variety of waterbirds.

Mallard response to experimental human disturbance on sanctuary areas is mediated by hunting

Wildlife Biology, EarlyView.
Wildlife managers often provide spatial sanctuaries for wildlife to escape both lethal (e.g. hunting) and non‐lethal (e.g. non‐consumptive recreation) human disturbance. However, as societal interest in outdoor recreation continues to climb, many areas face added pressure to allow recreation, yet studies increasingly demonstrate negative effects of ...

Waterbirds

Waterbirds
In the floodplain, dense gallery forests, shrublands, large grasslands, exposed mud areas, and seasonally isolated ponds are favorable feeding and breeding grounds for bird species in Tonle Sap Lake. They are home to a number of globally threatened and near-threatened species.

Hunting and fishing harvest data collection: a horizon scanning exercise from the French context

Wildlife Biology, EarlyView.
Legal and societal moves increasingly lead leisure hunting and fishing practitioners to record their harvest. The total number of individuals harvested per population per year is the minimum required information to feed into demographic models and allow science‐based management. Some few schemes record more detailed data, hence allowing better‐informed

Using a live‐streaming webcam to assess the behavioural responses of waterbirds to changes in the density of swans Cygnus spp.

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.

Visual observation to identify sexes in subspecies of adult Black Skimmers (Rynchops niger) [PDF]

, 2018
Identifying sexes in birds from visual observations could be a useful and inexpensive method. While sexual dichromatism and ornaments are readily used by observers, sexual size dimorphism can also be used to identify sexes in some bird species.
