I hear the first call...the "Who cooks for you" most often from the Barred owls but we do hear the "Caterwauling" from time to time. Often it is during the peak mating time which is February here mating. I believe it was our second February here that we heard them so went outside, this was like 10 pm, and there numerous owls flying around like crazy! We just stood on the porch and watched in amazement! Have never seen it again.
Gorgeous hawk GrammaChar!
