| Popis: | The little-known Eurasian Sparrowhawk of Macaronesia (Accipiter nisus granti), also named as the Macaronesian sparrowhawk, is endemic to Madeira Island and the Canary Islands (North Atlantic Ocean) and has the smallest area of distribution of the sparrowhawk subspecies. We studied the breeding biology of the Macaronesian sparrowhawk for the first time on Madeira Island, Portugal. Specifically, we described nests, tree nests, nest sites, and nesting territories, and we estimated incubation, hatching and fledging dates. Moreover, we evaluated the influence of altitude on the date of the initiation of breeding and measured the number of fledglings and the factors influencing this parameter. Most nesting territories (88.6%) were located in forest patches where valleys with watercourses were present. Breeding success (73.2% ± 0.1 SE, n = 18) and the mean number of young fledged per nest with eggs (2.27 ± 0.04) are lower than the values for the Canary Islands. Altitude influenced the date of the initiation of breeding, with pairs in lowlands ( Nest This work was supported by the project LIFE12 NAT/PT/000402 ‘‘Conservation of Macaronesian Sparrowhawk and Laurissilva habitat in Madeira Island,’’ cofinanced by the LIFE Program of the European Commission. |
