A late spring, early summer visit to Lee Valley Regional Park turned up Cuckoo, a surprise singing Nightingale (bit late) and an even more surprising female Smew. Not so surprising were the Garden Warbler, which are reliable at this site.
Towards the end of the month I visited another possible patch, Trent Park, a large area of mixed wood and meadow. It's also very popular for events and, as I found, 'illegal' ravers who were having a good time in a small patch of woodland; their music could be heard during almost all of my walk! The best section was at the far north east of the park where the pine woods met agricultural fields, where I saw a family of Goldcrest and a Yellowhammer respectively.
