Using time‐series remote sensing to identify and track individual bird nests at large scales

open access: yesRemote Sensing in Ecology and Conservation, Volume 12, Issue 3, Page 414-427, June 2026.
Time‐series airborne imagery can potentially track individuals over time to collect information beyond one‐off counts. Using weekly UAS‐based imagery of wading bird colonies, we develop an automated approach to identifying nests. Our algorithmic approach detected 68–74% of known nests and exhibited similar performance to human review of imagery ...
