We have a pair of hawks nesting in an Aspen tree near our back fence!! We first saw them last weekend, but didn't know they were using the nest, which we first discovered last spring. It appeared to be abandoned. On Wednesday, we saw one of the pair carrying a stick to the nest, and they have been there ever since. They're very vocal. My project now is to identify the species. We're going to stay away from the area as much as we can, but need to go back there to untangle and remove some old barbed wire from a rotted fence before we bring Buck and "friend" home.
