If you remember, last week I reported a single egg inside the nest box at the Train Tunnel, it now has three nest mates. The female was incubating as I approached and took flight just before I reached to box.
As usual, I checked all of our six nest boxes here at the Museum and found them all empty except the Train Tunnel box. So far this box has had one failed nest and has fledged four young. This is the third attempt at a nest in this box.
