All was going as planned until a few days ago, when some house sparrows and a woodpecker began pestering the wrens — perching on their house, blocking their entrance. “A House Sparrow Killed My Wren,” read the headline on a story posted by Jennifer on wild-bird-watching.com. She wrote that a sparrow began blocking the entrance to her wren house and that her husband had seen the birds squabbling. He advised me to make sure that the opening to the wren house was large enough for the occupants but too small for the sparrows. House wrens are among the best singers, but they are hardly more popular than house sparrows.
