A follow up to the barn swallows. Just witnessed them in action against a crow that decided to take a bath in the bog. All of sudden 8 swallows descend upon the poor bird just looking for a bath. They were squawking and dive bombing that crow until he left and one escorted him out of the yard. Those swallows are pretty cool birds.Very nice and such clear water! Plants will fill in nice after awhile. Wonder if you will end up w/a net eventually?
