Aberrant Moorhen

Spent a few hours this afternoon at the London Wetland Centre with Rachel. Rather quiet with 2 Common Tern, c30 Sand Martin around the artificial next bank, 1 Barn Swallow, 1 Willow Warbler, 1 Chiffchaff, 2(H) Reed Warbler, 2 Redshank, 10 Northern Lapwing (including 1 with a chick and 4 on nests), 2 Little Grebe (including 1 on a nest), 3m Northern Shoveler, 3 Gadwall, and quite a few Common Teal and Tufted Duck remaining.

This interesting aberrant adult Common Moorhen with no red pigment was wandering around in World Wetlands. Check out the complete yellow bill and bright greenish legs with no red base to the tibia. The bird was repeatedly chased away by the 'normal' moorhens. This is actually the second 'yellow-billed' moorhen I've seen at the London Wetland Centre. My notes from 31 July 2005 record "1 with complete yellow bill and browner on back than nearby normal plumaged birds".

What is 'normal' anyway?


Common Chiffchaff

Flowering plants included a few Snake's Head Fritillary Fritillaria meleagris, Cowslip Primula veris, Marsh Marigold Caltha palustris and Cuckoo Flower Cardamine pratensis.
