bubo(redirected from climatic bubo)
Also found in: Dictionary, Thesaurus, Medical.
a genus of birds of the order Strigiformes. The body length varies from 36 to 75 cm. The facial disk is not well defined. The digits are feathered. There are hornlike tufts of feather on the sides of the head.
The genus comprises 12 species, which are found in Europe, Asia, Africa, and America. The USSR has one species, the eagle owl (B. bubo), which is distributed from the polar circle to the southern borders. The plumage varies from very light to reddish brown and often has markings; the back is darker.
Bubo are either crepuscular or nocturnal. Some species are sedentary, and some, migratory. Bubo inhabit forests, steppes, deserts, and mountains. Nests are built on the ground beneath trees, in washed-out hollows of ravines, or in rock crevices. A clutch contains two or three, rarely four, eggs, which are incubated by the female for 35 days. The young fly well 100 days after hatching. Bubo feed on mammals—from mice to hares and young roe deer—birds, frogs, and large insects. Although bubo benefit man by destroying rodents, they sometimes prove harmful to the hunting industry.
