Updates to the Wetland Bird Survey counts for this season.
The slightly higher numbers seen on WeBS sites in 1995-96, 2009-10 and 2010-2011 probably reflect the colder winters in those years.
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.
These graphs will be updated as more data comes in.
