On 22 June I did a half-day visit to London Wetland Centre and got in just after they opened at around 09:30am. There was a lot of breeding activity going on with Coots, Common Moorhen and Tufted Ducks with chicks. Other immatures recorded were those of Blue Tits and Lapwings. Unfortunately I didn't come across many waders; Starlings were around in huge numbers and I counted at least 10-12 Grey Herons. Below are some photos from the visits and some notes on them.
Some of the other species listed were Black-headed and Common Gulls, Great Tit, Great Crested Grebe, Chaffinch, Little Ringed Plover, Common Tern and Sand Martins. I did however miss out apparently on a Tawny Owl outside the Wetland Centre that was in one of the big trees along the road.
