The boys are back in town

My male wrens are finally starting to arrive en masse! (The picture above is the view looking straight down into a nest box with some sticks that a male wren has placed there to begin construction of his nest.) The males were about a week late, so I was starting to get worried. I'm guessing that the late snowstorm we had slowed them down some. But, as of Sunday I had 28 (out of 68) boxes where a male had begun nest construction. I expect more males every day and that the females will be returning sometime next week.
