I paid a visit to Childwall Woods and Fields with my son Dylan yesterday (this is his favourite place). We managed to find a reeling Grasshopper Warbler, Whitethroats, Willow Warblers, Chiff Chaffs, Great Spotted Woodpecker, Nuthatch, Buzzard, Comma, and Large Skipper.
There is also a great display of Southern Marsh and Common Spotted Orchids, with large hybrids dominating.
This site has really improved over the years thanks to a number of groups and organisations such as; Lancashire wildlife trust, LCC, and the local friends group. They have produced a very rich and varied site.
