NOTE: This observation is a continuation of a previous post. The earlier article can be found here: Great Horned Owl – VCDB Nest
There are at least two Great Horned Owl’s nests in the swampy area southwest corner of the Village Creek Drying Bed. The owls have set up in an active Great Blue Heron rookery, and their nest are modified and enlarged heron nests.
Several dozen Great Blue Herons occupy nests in the surrounding trees, creating an interesting dynamic. Surely, the Great Horned Owls will prey on heron chicks in order to keep their own owlets well fed. Even the adult herons would be relatively easy pickings after dark.
But, the best information I had found so far indicates that this is not the case. The Great Blue Herons I have observed seemed unconcerned about the predator in their midst. There may be more to this nesting arrangement than first meets the eye.
