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

frontiermetrics: An R Package for Characterizing Deforestation Frontiers
Remote Sensing in Ecology and Conservation, EarlyView.Deforestation frontiers are major drivers of biodiversity loss, carbon emissions, and ecosystem degradation, yet our understanding of how deforestation progresses in these frontiers is limited. We present frontiermetrics, an R package to quantify a range of metrics describing the speed, severity, and spatio‐temporal patterns of forest loss. The package
