Our barn swallows have been returning during the second or third week of March for years. They left for South American quite early last year because of the drought, and I'm really hoping they did not perish. We tried to sit out on the back porch tonight, but the mosquitoes are already bad. Need my swallows! They are such pretty little birds. I know some don't like their mud nests or the poop on the porch, but I have a little power washer to clean the porches and I think the nests are works of art.
