Behavior

• The nocturnal bird sometimes forage during the day
• They fly and shift up and down to adjust themselves with the changing temperatures
• The spotted owl prefers to stay alone except for the breeding season

Mating and Reproduction

The copulation season usually starts from spring and lasts till either summer or fall. Males and females form monogamous pairs and after 4-6 weeks females lay white to grayish 1-4 eggs sizing around 2 inches. They are incubated for 28-32 days by females.

Life-cycle

Hatchlings are born blind and usually covered in down. They start moving and flying out of the nest after 4-5 weeks although they stay in touch with their parents for another 2-3 months. The young owls reach sexual maturity around the age of 2.

Interesting Facts

• Spotted owls are often confused with barred owls and in some areas, two species are crossed to beget “sparred owls”
• Adult spotted owls not necessarily breed every year, rather they take a break that can be as long as 5-6 years
• Roosting owls preen each others
• The oldest reported spotted owl was a female aging 21 years
