Welcome to a new season of the Osprey Cam at Blackwater National Wildlife Refuge on the Eastern Shore of Maryland.
This is our 14th year broadcasting images from this osprey platform located along the Wildlife Drive at Blackwater Refuge. Last year we appeared to have newbie parents who laid their eggs very late, and then had two of their three eggs “disappear” close to hatching. The one chick that did hatch died within the week, so it was a disappointing season.
Our 2014 pair (we’re not sure if it’s the same couple as in 2013) returned from migration and quickly set about filling the nest with many sticks. They then laid their three eggs in a timely fashion and have been incubating in an efficient way ever since. So we have high hopes that this year we will have a successful nest, since we’re off to a good start.
Our parents have made it a bit challenging to see the eggs in the nest, since they put up a stick “wall” between the camera and the nest cup, but based on what we’re seeing on the TV monitor at our Blackwater NWR Visitor Center, we definitely see three eggs, and we don’t believe there is a fourth. The scorecard looks like this based on our best guess of when the eggs appeared:
Possible hatch: 5/31
Possible hatch: 6/3
Possible hatch: 6/6
Both osprey parents assist with incubating the eggs, although the female does it more often and is the parent on the nest at night. While the larger female protects the eggs at night, the male likely roosts in a nearby tree.
Our regular cam watchers know that during the past winter we saw a Great horned owl on the osprey platform at night. Great horned owls are a legitimate threat to ospreys and have been known to kill female ospreys on their nests and also kill the chicks. In places like Jug Bay Natural Area on the Patuxent River in Maryland, Great horned owls have been a threat to ospreys, but we’ve been fortunate at Blackwater NWR that the owls seem to abandon the platform once the adult osprey begins staying on the nest all night. Hopefully this trend will continue.
We thank everyone for joining us for another season with our Osprey Cam, and we also thank those who have sent in photos to our gallery. If you’re new to our Osprey Cam and don’t know how to submit photos, you can find instructions here.
