Stihl is a Northern Saw-whet Owl (Aegolius acadicus) and is a woodland bird, with a preference for coniferous forests and riparian woodlands. Native to North America, these are small owls, generally 18 to 20 cm (7-8 inches) in height and lack feather tufts on the head. They are nocturnal predators preying primarily on small mammals such as deer mice. They can locate food by hearing alone using their asymmetrical ears to locate sounds of their prey. Saw-whet Owls are one of the very few owls thought to practice polyandry as a mating strategy. In this form of polygamy, the female leaves her first group of young to the male to rear on his own, while she locates another male and breeds again. Using this strategy she passes her genetic material on to a greater number of offspring. Their common name derives from their call that resembles a file sharpening a crosscut saw. Saw-whet owls benefit from nesting boxes placed where natural cavities are scarce. Nest box plans can be found here on our website.
Timber is a Northern Saw-whet Owl (Aegolius acadicus), a highly nocturnal cavity nesting species. Closely associated with forested habitats, they are actually fairly common, their range extending from southern Canada through all wooded regions of the United States and into the Sierra Madre of Mexico. Living in dense forest habitat, they rarely encounter humans and are therefore one of the least wary of the owls. They are a favorite of photographers when spotted roosting during the day near tree trunks, commonly of coniferous species. These roosting sites provide protection from large predators but allow for a variety of escape routes as well. Loss of forested habitat may impact this species, but placement of nesting boxes can benefit them in areas where nesting cavities are scarce. Weighing about 2.6 ounces, they are one of the smallest owls. Nest box plans can be found here on our website.
