Updates to the Wetland Bird Survey counts for this season.
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.
Note that totals for any month this season may be updated as more counts come in. Canada Geese often feed in fields away from the estuaries where they are not counted, so monthly totals can seem erratic.
The maximum count can be in any month, but in recent years has been in September.
