Fall Visitors to the Heron Nest
Sleepless yet attentive viewers reported seeing a pair of Great Horned Owls visiting the heron tree in Sapsucker Woods during the early morning hours of October 9, 2012.
Great Horned Owls nest primarily in the old nests of other species and do sometimes take over heron nests and use them for breeding, although this particular site may be too exposed. Only time will tell if the owls are truly interested in this site; for now, enjoy the sounds of their soft hooting and the fantastic views as they stroll right toward the camera.
Persistent viewers of the pan-tilt-zoom heron cam in Sapsucker Woods have spotted more than 12 species frequenting the heron tree and surrounding environment this fall (see the gallery). Thanks to all who snapped screenshots and submitted them to our bird cams photo pool on Flickr. Learn about some of the other denizens of Sapsucker Woods, and keep tuning in!
