swallow at the door

I have watched these birds fly round for days now, back and to, think they must have a nest and he/she is watching over them. I could have reached up and touched her/him but didnt seem to want to move, I just hope nobody finds the nest.

my camera was shaking because i was trying to rush incase the swallow took flight but didnt seem that bothered.

I love nature it is my inspiration.
