A pair of house wrens was in a nest box!! As far as I know, this is the first nesting of this species at the FWG. I was listening to the redstarts raising a ruckus, when I became aware of a wren calling from somewhere behind me. Imagine my surprise when one popped out of a nest box, and another flew to the top. I was able to get photographs without going close, although I've had to crop them a lot. I would hate to see them disturbed. It is not that house wrens are uncommon, or uncommon nesters in gardens, but just that we've not had them nesting at FWG before (as far as I know!).
