Late Summer

Its mid July now.
Most birds are failry quiet now.
From the meadows  a churr from a Sedge Warbler can still be heard, but little else. Reed Buntings flit around, but are little heard.
Last night I was watchihng a Barn Owl hunting at about half six, when I suddenly heard an alarm from an unusual source - a Common Tern. not many of these birds can come across Barn Owls.
This morning I watched three flying on south down the valley.
 Last night whilst dog walking I found three glow worms, an extra one from those I saw the night before. Quite bright they were clearly visible up to 15 metres away.
