Runcorn Bridge and Fiddlers Ferry Power Station with Dunlin flock over Mount Manisty, Stanlow.
The same flock wheeling in tight formation with Weston Point behind.
Can you estimate the number in the flock? If you have the patience then the WeBS team are looking for your time. Just one day a month for a couple of hours to fill in the gaps in coverage all along the banks of the river. If you are interested drop Dermot Smith (who is co-ordinating the counts) an email firstname.lastname@example.org, or find the Mersey Estuary WeBS on Facebook at http://www.facebook.com/#!/pages/Mersey-Estuary-WeBS/216178248450013.
