摘要：We studied the nesting biology and behavior of the Ornate Hawk-Eagle (Spizaetus ornatus) from a presumed same pair at two alternate nests in Belize over the course of a nineyear periodintermittentlyfrom 23 October 2004 to 15 March2012.Data was collected on theincubation period, post-fledging dependency period, habitat, nest-sitecharacteristics, and diet. Nest-site characteristics data was collected from four nests of three different pairs. Nesting occurred every other year, except whenthey nested successive yearsin 2010 and 2011. Egg-laying occurred in early March during the onset of the dry season and the incubation period was 44-46 days. The female did 96.6 % (53.4 of 55.3 h observed) of the incubating and the male did all of the foraging for both adults during the incubation period. Fledging occurred at 70-84 daysin early July, the beginning of the rainy season. The dependency period was up to 12 monthsof three successfully fledged juveniles, in which we observed them within 250 m of the neston all occasions. Of six prey items observed, five were medium(230-500 g)to large birds(3000-5000 g)
