We heard our first cuckoo of 2011 during this morning's guided walk.  I couldn't easily select one highlight, though, as we all saw a grasshopper warbler and several sedge warblers, and most saw a garden warbler.  Then there was the pair of little (ringed) plovers, displaying and nesting lapwings, a Cetti's warbler trying to deafen us, and the marsh harriers and common buzzards soaring overhead.

We also saw quite a few St Mark's flies - 9 days early!
