If there was a lack of bird life then there was a profusion of butterfiles
I don't know a lot about them but there were several different ones.
These seemed to really like the thistles.
It was too hot even for the sky larks. Apart from a couple of crows the only other birds that I saw were the ducks on the pond, trying to avoid the idiots that let their dogs bathe and cool off in it.
I managed to keep my counsel but it was a close run thing as one fool threw a stick for her dog to go and collect. There was a brief flurry of movement as the ducks scattered to get out of the way.
