Clennon Valley

After hearing of a Bittern roosting in the zoo at the end of last week I tried the valley during the morning and at dusk tonight - no sign - but other birds included: 3-4 Chiffchaffs, 4 Goldcrest, 3 Teal, 2 Shoveler, 7 Water Rail. This evening one Little Egret (headed toward the zoo at dusk), a roost of 137 (and probably more!) Magpies, 8 Grey Wagtail with a small number of Pieds roosting around the middle pond.
