In the photo above, four Ospreys are visible — although the nestling behind the red screening is admittedly hard to see.
The nest has been registered with the New Jersey Osprey Project. It is officially Nest 042-B-001.
Here is a link to a South Bergenite column on Ospreys this spring.
On the "jump" is a photo with an arrow pointing to each Osprey. Nos. 1 and 2 are the nestlings; 3 and 4 are the proud parents.
No. 1 is hardest to see, hence the enlarged number.
