The PixController folks are indicating that the oldest eaglet, H2, fell from the nest. Some who watched are not sure that it was not a fledge. But it is good to know that appropriate folks have been notified so that it can be checked. Here is what was written on the PixController Facebook page: along with a link to video of the event
We have had a situation at the Hays bald eagle nest this evening. H2, the oldest eaglet, appears to have fallen from the nest around 8:45 PM this evening. We have notified the Pennsylvania Game Commission and the Western PA Audubon Society to properly deal with this situation. We will keep everyone updated on this issue as best as we can.
