We studied the breeding biology and diet of the endemic Madagascar Buzzard Buteo brachypterus, in Bemanevika Protected Area, northern Madagascar, in 2017 and 2018. The breeding season occurred during the dry season, nest building from early August to early September, egg laying from late August to early October, hatching between September and October and fledging between November and December (beginning of the wet season). Laying peaked in September (n = 24 pairs). Twenty-four breeding pairs were observed of which nine pairs had one-egg clutches and fifteen pairs had two-egg clutches. The average clutch size was 1.6 ± 0.5 eggs (n = 24 nests). The incubation period was 36.2 ± 1.1 days (range 35-38 days, n = 16 nests). The nestling period was 48 ± 3.9 days of age (range 43-56 days, n = 16 nests). Of 39 eggs laid in the 24 breeding attempts, 34 (87.2%) hatched and 22 (64.7%) of those hatchling fledged. Of the 24 fully-documented breeding attempts, 0.91 young fledged per breeding attempt and overall nest success was 79.2 %. The Madagascar Buzzard diet of 515 identified prey items was composed of reptiles (37.3%), birds (35%), small mammals (19%), invertebrates (8.3%) and amphibians (0.4%).
