- Great horned owls begin mating in January/February, with the male calling and performing a courtship dance to impress the larger female.
- They nest in tree hollows, abandoned nests of other birds, or even on the ground, laying 2-3 eggs which hatch after 5 weeks.
- The parents are kept busy supplying food like mice, squirrels, and various birds to the hungry owlets as they grow and develop feathers over time.
