[cobirds] Great-horned Owls--started hooting (Denver Co)

Hi

On recent, loosening up the back, evening walks around the greater DU area in Denver, I've detected Great-horned Owls hooting starting at 7PM and continuing. Actually I've heard them hooting, to a lesser degree, during the day. The extent of their hooting suggest they are already setting up territories, the end of September! Anyone else hearing them?
