THE OWLS
Australian Hawk Owls
Australia is especially rich in species of this genus, there being some nine or ten, among them the Powerful Owl (N. strenua), which is the largest of the group, sometimes reaching a length of twenty-four inches. It is mostly ashy brown above, numerously banded with white or pale brown, the wings being barred with rufous and white, and the tail with six to nine white bars, while the lower parts are mostly white barred with brown on the flanks and sides.
Boobook Owl
Another well-known Australian species is the Boobook Owl (N. boobook), a bird hardly half the size of its great relative. It is deep chocolate-brown above, darker on the head, with the scapulars and wing-coverts spotted with white, the tail dark brown crossed by about eight light bands, while the under parts are bright ochraceous, each feather being centrally streaked with brown.
