At the end of the first month of the BTO/SOS wintering bird atlas, here are the number of species found so far in some tetrads around Rye and the levels. (A tetrad is a 2 x 2 km area of the National Grid.)
TQ 92A (west side of Rye, R.Tillingham, Leasam) 40
TQ 92B (Iden to Rye Foreign) 32
TQ 92F (east side of Rye, East Guldeford) 67
TQ 92G (Saltbarn, Houghton Green, Cliff Farm) 48
TQ 92H (Iden Lock, Bosney) 37
TQ 92K (Moneypenny and levels to east) 34
Still early days - many tetrads both out on the levels and further inland have yet to be visited.
