Wrens Have Moved In

There are many swallows still nesting with 1-7 day old chicks. I did not check them all. The Bluebirds have pretty much disappeared. The one pair attempting to nest on the South side made a brief appearance near one box, but even that box has wren eggs now.

With so many empty boxes, because the swallows are also down to close to half the number last year, the wrens have moved in early. At least 5 boxes out of 32 have wrens. One had hatched young, the other four were at this stage. It is a bit early, as the wrens nest in about this number but normally in July.


There is really nothing I can do. I would either need to close the boxes or remove them all after the end of May. It is the job of any Bluebirds next spring to fight with the wrens for the boxes again.
