Average hatching date in southwestern Alaska: mid-June; mid-July in northern Yukon. Clutch size is 2-7, largest when lemmings are abundant). Incubation, mainly by female, lasts 28-31 days. Young are tended by both parents, fly well at about 5-6 weeks; some may be independent a month or less after attaining flight (Palmer 1988). First breeds probably at 2 years. Number of breeding pairs and/or breeding success usually increase with lemming/vole abundance.","ecologyComments":"Productivity fluctuates greatly in relation to prey density. Winter territory encompasses about 10-16 sq km (Zarn 1974); may aggregate and roost in groups where food is abundant. Nesting territory probably as small as 5-6 sq km when prey density high (Palmer 1988).","habitatComments":"Nonbreeding: grasslands, field, marshes, sagebrush flats, and open cultivated areas; sometimes rat-infested garbage dumps. Nests on cliffs (typically) or in trees in arctic and subarctic, in tundra, mountain sides, forests with plenty of open ground. Sometimes nests on the ground or on man-made structures. Apparently nests more commonly along coasts and on marine islands. May compete for nest sites with raven, peregrine falcon, and gyrfalcon (latter two often use nests built by rough-legged hawk). May use same nest in successive years.","generalDescription":null,"diagnosticCharacteristics":null,"speciesMarineHabitats":[],"speciesTerrestrialHabitats":[{"cagTerrHabId":-104150,"terrestrialHabitat":{"id":5,"terrestrialHabitatDescEn":"Woodland - Conifer","terrestrialHabitatDescEs":"Lote de madera - Conífera","terrestrialHabitatDescFr":"Terrain boisé — Résineux","displayOrder":7}},{"cagTerrHabId":-104144,"terrestrialHabitat":{"id":8,"terrestrialHabitatDescEn":"Savanna","terrestrialHabitatDescEs":"Sabana","terrestrialHabitatDescFr":"Savane","displayOrder":10}},{"cagTerrHabId":-104145,"terrestrialHabitat":{"id":9,"terrestrialHabitatDescEn":"Grassland/herbaceous","terrestrialHabitatDescEs":"Pastizales/cobertura herbácea","terrestrialHabitatDescFr":"Prairie/couverture herbacée","displayOrder":11}},{"cagTerrHabId":-104146,"terrestrialHabitat":{"id":11,"terrestrialHabitatDescEn":"Desert","terrestrialHabitatDescEs":"Desierto","terrestrialHabitatDescFr":"Désert","displayOrder":13}},{"cagTerrHabId":-104147,"terrestrialHabitat":{"id":13,"terrestrialHabitatDescEn":"Tundra","terrestrialHabitatDescEs":"Tundra","terrestrialHabitatDescFr":"Toundra","displayOrder":15}},{"cagTerrHabId":-104148,"terrestrialHabitat":{"id":18,"terrestrialHabitatDescEn":"Cliff","terrestrialHabitatDescEs":"Acantilado","terrestrialHabitatDescFr":"Falaise","displayOrder":21}},{"cagTerrHabId":-104149,"terrestrialHabitat":{"id":19,"terrestrialHabitatDescEn":"Cropland/hedgerow","terrestrialHabitatDescEs":"Tierras cultivadas/cerco vivo","terrestrialHabitatDescFr":"Terre cultivée/haie","displayOrder":22}}],"speciesRiverineHabitats":[],"speciesPalustrineHabitats":[{"cagPalusHabId":-100837,"palustrineHabitat":{"id":2,"palustrineHabitatDescEn":"HERBACEOUS WETLAND","palustrineHabitatDescEs":"HUMEDAL HERBÁCEO","palustrineHabitatDescFr":"TERRE HUMIDE HERBACÉE","displayOrder":2}},{"cagPalusHabId":-100838,"palustrineHabitat":{"id":6,"palustrineHabitatDescEn":"Riparian","palustrineHabitatDescEs":"Ribereño","palustrineHabitatDescFr":"Riverain","displayOrder":6}}],"speciesLacustrineHabitats":[],"speciesSubterraneanHabitats":[],"speciesEstuarineHabitats":[]},"primaryReference":{"id":134424,"citation":"American Ornithologists' Union (AOU). 1998.
