Updates to the Wetland Bird Survey counts for this season.
The effect of the cold winters of 2010-11 to 2012-13 is clearly shown on this graph. The effect of the ‘Beast from East’ (cold spring of 2018) may simply have been a set-back in the overall recovery from the previous cold winters.
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.
