Middlesex Filter Beds was surprisingly quiet this morning albeit for the song of the more common species. Of note a single Chiffchaff, a pair of Tufted Duck, a pair of Gadwall, and an overflying Sparrowhawk were present.
Waterworks NR produced my first Sand Martin of the spring with a single bird flying east. The Cetti's Warbler was particularly vocal today as were two Blackcap, and two Chiffchaff, one of which had an interesting inflexion to its' last two notes. On the water, three Little Grebe, a pair of Shoveler, a pair of Tufted Duck, and 15 Teal were noted.
