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 nine year period intermittently from 23 October 2004 to 15 March 2012. Data was collected on the incubation period, post-fledging dependency period, habitat, nest-site characteristics, and diet. Nest-site characteristics data was collected from four nests of three different pairs. Nesting occurred every other year, except when they nested successive years in 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 days in early July, the beginning of the rainy season. The dependency period was up to 12 months of three successfully fledged juveniles, in which we observed them within 250 m of the nest on all occasions. Of six prey items observed, five were medium (230-500 g) to large birds (3000- 5000 g).
