Thanks you Tony and Bob for your comments - I can assure you I do not have a flock of trained birds to photograph! - It comes from that basic attribute requried by fishermen and wildlife photographers - Patience!
Today - whilst cutting the lawn - play was interrupted by a family party of newly fledged Pied Wagtails. This afternoon sat in a gorse thicket on some farmland near Llanrhysted, for a couple of hours - and here's the results - Reed Bunting and Linnet - photographed - other birds seen included Whitethroat, Willow Warbler and Chiffchaff.
