Since last week’s inspection of the six nest boxes at the museum, at least five eggs have hatched, four nestlings have fledged, and a new nest has been started.

The house wren eggs that were in the nest box at the Cow Pasture have hatched. The nest held six eggs, but it’s difficult to determine if there are five or six nestlings in the nest. See for yourself at left.

There has been no activity in the nest box on the service road in Explore the Wild.

The four bluebirds that had occupied the nest box at Into the Mist have fledged, leaving behind a very nasty mess.

Last week there were several twigs placed in the nest box on the east side of the parking deck, an indication of house wren industry. But, there has been nothing new added to the nest.

After the five bluebirds fledged from the nest box on the west side of the parking deck, I did a bit of cleaning and placed a new berry basket in the nest box. A house wren has started to build in the box. We will have to wait till next week to see if the wrens continue working on the nest.

The nest box at the Butterfly House is empty.

So, we now have at least five house wren nestlings, a new house wren nest started, and four new bluebirds flying about our campus. There’s still time for a second brood for the bluebirds.
