Producing breeding population estimates to monitor Little Egret trends

Author:

Published: 2026

Data from the Heronries Census and the Rare Breeding Birds Panel (RBBP) were combined to produce population estimates for Little Egret. The population was estimated at 2,236 pairs / apparently occupied nests in the UK and the Channel Islands in 2022 (there are no breeding records yet for the Isle of Man), which was around 40% higher than the total number of nests reported to the RBBP in that year.
