Swallows or Swifts

One swallow doesn't make a Summer but here's a pair, and it is June now so maybe Summer is on its way :)

Swallows and Swifts are often confused, so while the main is a pair of swallows there's a shot of a swift as the extra.  I love the interaction between the two swallows so that's why I've chosen it as the main, although getting the shot of the swift in flight coming head on towards me was the more difficult of the two shots.
