Twitch for the Black-crowned Night Heron at Stockers Lake (20 and 21 June)

After getting the news of a Black-crowned Night Heron at Stockers lake on the 19th June I headed down to the lake after school on the following day and arrived at around 3:40pm.  Unfortunately, no records were submitted since 1:50 when it was last reported, and apparently it had been seen departing the reserve later the previous day (as a result the mixed messages didn't help).  I didn't find the bird, however, other commoner birds around on the 21st June included Great Crested Grebe, Common Terns, 2 (possibly 3) Little Egrets, Grey Herons, Reed Warbler (with 2 chicks) and a pair of Sedge Warbler (also with 2 hicks).
