If at all possible, I will try to get a video. He was on top of the nest box just outside my kitchen window and facing the main tomato garden. Wrens are great for keeping tomato plants bug-free. He's hopping up and down on top of the box. Sometimes with both feet, sometimes on first the left foot - hop, hop, hop - and then the right foot - hop, hop, hop. Sometimes his hops take him up a couple inches; sometimes a foot or more. He has both wings dropped down with his head bobbing. Then holds first one wing and then the other out at various angles and contortions...all the while doing the multi-footed polka, and singing his fool heart out the entire time. He flies straight up a couple feet and then zig-zags back down to the nest box top. Again, singing that fool heart out. I expected him to have a major coronary at any second. She looked at him; she looked in the box, (a very fine Coveside chickadee box, with slate squirrel guard, by the way) did the birdy version of an eye roll, and zoomed off. Her mama raised her better than to hang out with that sort of boy. But then...good girls and bad boys...we know how that story plays out at times!

Do the birds not mind you "messing" with their homes? What a wonderful hobby you have and how grateful your birds must be to you!

If I recall, March is the month! Mine is still on the ground because the telescoping pole is not telescoping. I have sprayed with lubricant but don't know if I can get it tall enough at the recommended 15 feet.

I did not know any of that about Purple Martins!! Congratulations on your full house(es)!! That is a lot of eggs to watch and a lot of baby birds coming up. Cool picture!! Thanks for sharing that. I had a late (to me) nesting of a pair of Carolina Chickadees. They had 3 youngsters and they have now flown the coop! Birdwatching is so much fun.
