heathland and gaileys

today i went birding with my mom, we went to gaileys and we saw cormorants 10+, grey heron x3, black headed gulls 50+, pied wagtail x1, blue tit 3-5, kestrel x1. we saw a man there who told us about belvide reservoir and that we needed a permit and he told us about some heathland on cocksparrow lane, so we ate lunch and went there, we didnt see much but i saw some carrion crows and wood pigeons and i saw a yellow bird fly away and i think it was a yellowhammer.
