Grey Heron – WeBS 2021-22

Ardea cinerea – CREYR GLAS – Breeding resident

Updates to the Wetland Bird Survey counts for this season.

Herons were not regularly counted for WeBS until 1993.

Data for June and July are collected by Jane Hodges during the annual surveillance of summer shelduck populations on the Cleddau Estuary complex. There are no counts in August. The September to March data is collected from sites across Pembrokeshire (including the Teifi Estuary) for the BTO Wetland Bird Survey.

Maximum counts are usually in the autumn, coinciding with dispersal from nest sites. This graph will be updated as more counts come in.
