They swallow their prey whole, and digest all but the bones, fur or feathers. These pellets can frequently be found near the nest, and provide information about what the owls have been eating. Great Horned Owls do not build their own nest, but move in on existing nests, such as an old hawk's nest. A pair usually will not occupy its nest until a few days before the eggs are laid. One to four eggs are produced, staggered over several days so they will also hatch over several days.
Owls are mainly nocturnal birds, frequently heard before they are seen.
Listen for the low, muffled series of hoots in early evening or predawn hours. Take the path through the woods to the right, or keep walking south on the paved road, looking toward the stream and woods. This is one of their favorite hang outs. Once you hear the hoots, look high up in the trees for a large cylindrical shape near the trunk. You should be able to pick them out by their silhouette.
