I'm by no means an expert but I think the butterfly is a Sooty Copper. Germain, one of our members, is much more knowledgeable than me and will be able to confirm or correct my ID.
The bird looks like a Crag Martin to me.

The bird looks like a crag martin to me too, my first thought was a sand martin but when I saw Tony's reply I looked in my bird book and I had never heard of a crag martin before but in my opinion Tony got it right.
