The Northern Hawk-Owl (Surnia ulula), or Northern Hawk Owl in North America, is a non-migratory owl that usually stays within its breeding range, though it sometimes irrupts southward. It is one of the few owls that is not nocturnal or crepuscular. This is the only living species in the genus Surnia of the family Strigidae, the "typical" owls (as opposed to barn owls, Tytonidae). The species is sometimes called simply the Hawk Owl; however, many species of owls in the Ninox genus are also called "hawk owls".

Famous quotes containing the word northern:
“The note of the white-throated sparrow, a very inspiriting but almost wiry sound, was first heard in the morning, and with this all the woods rang. This was the prevailing bird in the northern part of Maine. The forest generally was alive with them at this season, and they were proportionally numerous and musical about Bangor. They evidently breed in that State.”
—Henry David Thoreau (1817–1862)
