This survey is on the breeding ecology of Goshawk [Northern Goshawk] Accipiter gentilis inhabiting in Eomjeong-myeon, Chungju-si, Chungcheongbuk-do from April 2007 to August 2009. Laid of eggs starts incubation period 38.3±1.66 days. Total number of eggs laid 28, and 3.1±0.78 in clutch size. The eggs had 53.3±1.61 ㎜ of length, 4.08±0.96 ㎜ of width, and 43.7±1.60g of weight. The color of the egg was light blue. Hatching success rate among 28 eggs was 92.9% (26 eggs), and fledgling success rate was 100% (26 birds). During the breeding period, the female barely left but concentrates on her mission and the male hunts a variety of mammalian; Eurasian red squirrels Sciurus vulgaris (8%), and avian species, Rufous turtle dove Streptopelia orientalis (28%), and feeds his family around its nest. The male also incubates eggs when the female-bird left for a while. After 4weeks from incubation, it is verified that the hunted mammalian is increased.
