tree swallows

for some of this month we have had two tree swallows that have been coming and checking out the nest boxes that Connor made that are on the side of a railing on the uper deck. the two swallows have some times gone inside both of the boxes. some times one or both of the swallows land on the uper deck railing and sit thare for a while. some times when I am on the uper deck I get up to see how close I can get before it flys off I have got pretty close. Connor has taken some good photos when the swallows were on the deck.
