Watching For Second Clutches

Our native species, including Carolina Wrens, Eastern Bluebirds, and Tufted Titmice had their first nestings early in the spring, well ahead of the neotropical migrants. I had the satisfaction of seeing healthy juveniles resulting from these nestings. From late June into July we should have seen signs of second clutches from these same species as many of them are known to nest two and sometimes three times through the season. While I have not seen conclusive proof of nest success, I have evidence that nesting material was taken in the last few weeks (namely, from my hanging cotton ball.) And I am fairly certain the Wrens may be up to something, as their level of feeder activity has been generally high. We shall see if these characters have a midsummer youngster we can watch and enjoy.
