It’s mid-day and this adult great horned owl has hours to wait until darkness. In summer their hunting hours are much shorter than in winter, although they are busiest just after sunset and just before sunrise regardless of season. They prey on whatever is available. Hans Peeters, author of Field Guide to Owls of California and the West, states (page 191) that they have been known to even prey on house cats, bald eagles and canada geese. Bald eagles? Bald eagles weigh about 10 pounds. Great horned owls only weigh about three pounds. I wonder what they’d take if they weighed as much as an eagle?
