Junos Enterprise Routing, 2nd Edition

Colophon

The animal on the cover of Junos Enterprise Routing, second edition, is Tengmalm’s owl (Aegolius funereus), known in North America as the boreal owl. The bird’s namesake is Swedish naturalist Peter Gustaf Tengmalm, who is noted for his contributions to owl classification. The small owl (8–12 inches long) is distinguished by its pale or bright yellow eyes and its brown body spotted with white flecks. Its belly is usually off-white.

This solitary, largely unsociable owl lives in thick forests and high altitudes in Eurasia (it is common in Scandinavia). It is somewhat less prevalent in Alaska, Canada, and the northern United States. These owls often nest in the old homes of woodpeckers. These nocturnal hunters feed on birds, insects, and small mammals. Their asymmetrically located ears help them precisely locate prey by sound, even through snow.

Some identify the bird’s call with the peal of a funeral bell or a mourner’s cry; hence the funereus in its species name. The owl’s territorial call, by contrast, sounds like the word “poop” sung several times in rapid succession. When wooing a female, the male sings a series of stutters that eventually crescendo in a long trill of up to 350 notes. In North America, scientists named the owl after the Greek god of the north wind, Boreas, referring not to the owl’s voice, but to its northern habitats.
