Post fledging behavior of ferruginous hawks in North Dakota
Post-fledging activities of 18 Ferruginous Hawks (Buteo regalis) were studied in southcentral North Dakota during July and August 1979. The post-fledging period ranged from 10 to 40 d (mean = 23.1 d; N = 16). Haylands and native prairie grasslands were the principal land use types utilized by fledglings and adults. Mortality of young during post-fledging was 11% (N = 2).
