Anne D-N has also been spotting wildlife in her pond recently, finding a Three-spined Stickleback and a Common Frog. The stickleback are just entering their breeding phase, with the males acquiring red throats and bellies, as well as blue eyes! The one photographed was constructing a nest in a shallow area where there is some gravel. The frog appears from time to time in Anne's pond, but as yet there is no spawn.
Gill S also mentioned seeing a shoal of small fish - perhaps minnows or maybe trout - in the river from Sluice Wood today (28th), something she normally only sees around the Millennium Bridge.
