UPDATE: As noted in the comment below, they were able to move the camera in the GVSU nest box by remote control so we can now watch the falcons incubate their three eggs, and hopefully, raise their chicks. This confirms that we have TWO active nests. If you should be able to read any leg bands on the adults, please let me know!
Earlier this week I was finally able to see with my own eyes that we have a falcon incubating eggs in the Courthouse nest box. My best guess is that incubation started during the last week of March. (That would put hatching in late April or possibly early May.)
But on the same day I confirmed incubation, I heard the news that falcons are using the nest box that faces the river on top of GVSU’s Eberhard Center. There is a camera in that nest box, but over the years it has moved so only the far edge of the box can be seen. That means that a falcon wing or tail shows up occasionally and there is no way to tell if there are eggs present. Chances are that no adjustments will be made to the camera until the breeding season is definitely over, or until no falcons have been seen there for some time.
The Eberhard Center nest cam can be found here.
Please continue to send me where and when you are seeing falcons in the downtown area. Every bit of information will help us figure out if we really do have a second pair.
