When we first checked the boxes, we thought we already had a new egg in one, but determined eventually that it was an unhatched egg from the second brood last year. We should have done a final clean-out at the end of the summer. Our confusion at the start of this season is a good reminder of why it's a preferred practice to clean out the boxes at the end of the season. Some people take their boxes down; others close them up so nothing can get into them over the winter. We like the idea of leaving them accessible as roosting or shelter boxes, and we've seen some signs this year that they were used for that purpose.
Today we got some great views of a male and female bluebird at our prairie trail of four nestboxes, where we have three full nests but no eggs yet.
|Male Eastern Bluebird|
The many tiny scratches visible on the road sign suggest that it's a popular perching spot, as it was today.
