Last weekend we went by the Great Horned Owl nesting site in the Whitemud Ravine. Since the beginning of March the female has been in her cavity every day with the male perching high up in a nearby pine tree. This time, however, there was not sight of the female in the cavity. It is unlikely that the female would leave her tree, particularly during the day. A quick scan of the nearby trees revealed that the male was sitting in the same spot where I saw him the previous week. It is even more unlikely that the male would be there if the female would have left the nest. I concluded that the female indeed must have been in the nest, but quite likely was hunkered down inside the cavity making it impossible to see her from the outside. Based on our experience from last year nesting it appears that the cavity is quite deep as it was able to accommodate the large female and two sizable chicks.
