More pipisterlle bat observations

I have continued to watch the pipistrelle bats. They circle right over our garden wall and it I stand still they fly past sometimes only a foot away.
The best chance of photographing the bats is when they circles the tree across the track, as it provides a chance to predict where they are likely to fly next. They are very fast and the pictures have to be taken wide angle. At times the bats are only a foot off the ground as they hunts. There are always moths around the Red Valerian, particularly silver y-wing moths. The pictures are not excellent but you can see many of the features such as the finger bones that support the wings.
The bats now appear at about 8.45pm as it gets darker earlier. They forage for about 30 minutes, flying back and forth, often turning above my head as our garden is at the end of the track.
Its such a treat seeing these fascinating little mammals up close.
