Winter Atlas local summary
February 29th saw the end of the first winter season of the BTO Bird Atlas 2007-11, so here’s a brief round-up of the coverage in this part of Sussex from the BTO website. (There might be more records to come from the paper forms.) In the 32 tetrads in the area from Cliff End, Icklesham, Cock Marling and Peasmarsh east to the Kent border, 140 species were logged. The average of 45 species per tetrad conceals huge variations, from 103 species in TQ81X, which includes the Pannel valley, to just 9 in TQ91Y, a bleak stretch of beach at Jury’s Gap. The most widespread bird was the Carrion Crow (above) which can be found anywhere, even to the tideline. Little Egret and Marsh Harrier were both recorded in 11 tetrads, Buzzard in 5, Sparrowhawk in 15 and even Merlin in 7. The most widespread waders were not surprisingly Lapwings (20 tetrads) and Curlews (18), but the 14 tetrads for Snipe and 8 for Green Sandpiper were perhaps more than expected, as were the 14 tetrads for Barn Owl and 9 for Kingfisher. Conversely, Jays were logged in a mere 7 tetrads – such a conspicuous bird that it could hardly have been missed, unlike the secretive Treecreeper (just 4 tetrads). It was a poor winter for Siskins and Bramblings, both recorded in only 5 tetrads out of the 32. Well, that’s it for the winter period – now we have to wait until April to start all over again with the breeding bird atlas!
