LIVE WEBCAM - OSPREYS AT HOG ISLAND
The osprey cam is monitored by volunteers at Hog Island Audubon Camp, and hosted online by Explore.org.
An osprey nest, called an eyrie, is generally built on the top of a large tree or in coastal areas on cliff edges and rocks. Ospreys may also use man- made structures including electricity pylons, chimneys and nesting platforms. Man-made structures are used more regularly in North America than in Europe. Ospreys are site faithful and some nests may have been in use for some 20 years, with the birds adding to the nest each year. The nest is a large structure made of branches and twigs and lined with small twigs, moss, bark and grass. To build a new nest from scratch, it takes an osprey pair 14-21 days to complete.
If ospreys fail to breed successfully, they often start to build a new nest known as a ‘frustration eyrie’, which they may use for nesting the following year.
