A little romancing?
When swallow #2 (the one in front) landed on the nesting box and appeared to gaze adoringly at swallow #1, I wondered if they could be mates. Is there a little romancing going on amongst the swallows? Since I can't tell one swallow from another, I can only speculate. It's up to the swallows to decide.
