The tetrad coverage for the survey is up to around 50% but it would be good to increase it further. There are big gaps in the west of the county, along the Quantock fringes and a belt from Shapwick around Street over to the eastern border of the county. As surveying goes, surveying for Rooks is pretty easy! If you are at loose end this Easter weekend, give it a go!

This year’s survey period ends on 30th April. For full information click here.
