Over the winter I purchased a wooden bird shelter, and in the early spring, a friend helped me install it against the back wall of my townhouse. It remained mostly empty, occassionally visited by birds seeking shelter from the rain here and there. Yesterday evening I noticed the stem of a leaf sticking out from the shelter, and resolved to look in the morning to see what sort of activity might be taking place up there. A pleasant surprise occurred when I heard the pristine voice of a Carolina Wren, loudly singing the "seed-eater, seed-eater, seed-eater" song, and very close by, too. I happened to look up and glance at the side profile of the bird shelter and noticed a curved bill, opening and closing in time to the song. I found the singer! When she hopped down after a while and wandered off into the bushes to conduct wren business, I quickly went outside and carefully climbed up onto the AC unit to peek in: There is now a beautifully-crafted wren nest that was not there last week! She used lichens, a little reclamated pet fur, pine needles and leaves to create a round ball-like nest with a little entrance (no eggs inside as of today, but let's hope she does a second brood), and she can still use the lip of the shelter as a "balcony." I put it up, and she moved in. I've got a tennant :) Irene in Southside
