A session ringing swallows on Borth Bog last night with Jane Kelsall and Paul & John Leafe had more than the usual surprises. About 200 odd swallows and at least 1 Sand Martin gathered to roost and attracted the attention of a few other interested parties! An adult male Hen Harrier made two passes along the Leri followed by a swarm of swallows and then at dusk a mad dash (by me!) to the net produced this stunning juv female Merlin and a juv female Sparrowhawk. Water rails were calling in the reeds and a late juv Reed Warbler was also retrapped.
