Index of Subjects --Apple-Mail-57-1007301602 Content-Transfer-Encoding: 7bit Content-Type: text/plain; charset=US-ASCII; delsp=yes; format=flowed Randy is right on, at least for great horned owls in central Alberta, based on banding and tracking work at a field station north of Edmonton -- back in the 1960s/70s those owls that were territorial would stay on their territories in years of hare scarcity but would not nest. In Alberta the snowshoe hares are much more predictably cyclic in their population fluctuations, with peaks of abundance every 9 to 11 years, and then several years post-peak to rebuild their numbers. Cheers from Jim in Wolfville.
