The 2010 ferruginous hawk inventory and population analysis by Adam J. Moltzahn Download PDF EPUB FB2
The population estimate is based on the number of active nests detected during each inventory year. During the inventory, a population estimate of ± breeding pairs of ferruginous hawks was calculated.
The ferruginous hawk is a large raptor within the Grassland Natural Region of Alberta; inhabiting areas dominated by native prairie. The provincial ferruginous hawk The 2010 ferruginous hawk inventory and population analysis book has been Source: The ferruginous hawk inventory and population analysis.
The Ferruginous Hawk (Buteo regalis) is the largest North American hawk, with adults of the typical light-morph distinguished by a white or gray tail, nearly-white underparts, and dark-reddish legs (Bechard and Schmutz ).
They also exhibit a rust-colored shoulder patch, gray back and feathered tarsi (Glinski ). Although, initial analysis suggests it is related to a fluctuation of their primary prey species as a result of dry conditions of the previous year.
Overall, Alberta’s Ferruginous Hawk population remains significantly lower than the estimate, therefore, it remains essential for management actions to assist in the recovery of the species.

The Ferruginous Hawk (Buteo regalis; French: Buse rouilleuse) is a large, open country, diurnal raptor that occurs in western North America. In many respects, the Ferruginous Hawk is similar to the Golden Eagle. The Ferruginous Hawk has broad, long wings with rounded tips and a fan-shaped tail.
Two colour phases occur; a more common pale phase in which hawks have. Inhigh nesting densities of 3 species of hawks in the genus Buteo-Ferruginous Hawk (Buteo regalis), Red-tailed Hawk (B. jamaicensis), and Swainson's Hawk (B.

Ferruginous Hawk is a Species Conservation Concern, Level 1 species for New Mexico, with a total assessment score of It receives the highest vulnerability scores from PIF for its small population size, and a score of 4 for threats during the breeding season.

Migration Patterns, Timing, and Seasonal Destinations of Adult Ferruginous Hawks (Buteo regalis) Article in Journal of Raptor Research 52(3) September with 23 Reads. The Ferruginous Hawk (Buteo regalis) is a keystone raptor in arid-land ecosystems in western North America that is experiencing population declines in some regions.
determination of ferruginous hawk population trends. Therefore, apparent regional and local population trends may not accurately reflect range-wide population trends. As much as 20 percent of the winter range of the ferruginous hawk may be in the Mexican portion of the Great Plains, where little is known regarding its distribution, abundance,File Size: 1MB.
The Ferruginous Hawk is an open-country raptor that nests in 3 Canadian Provinces, 17 states in the United States, and winters as far south as central Mexico (Bechard and Schmutz ). The largest nesting populations are in southern Alberta (1, nesting pairs) and Wyoming (> pairs) (Olendorff ).
Ferruginous Hawk declines may be connected to habitat loss and changes in prey base across large parts of their distribution. See Farmer et al. () for more information. Gulf Coast: The coastal watch site in Corpus Christi, TX, had a significant increase in population counts during the last 10 years.
The ferruginous hawk (ferruginous = from Latin ferrum – iron, ferrugin- iron rust, iron-rust color – reddish-brown), Buteo regalis (Latin, royal hawk), is a large bird of prey and belongs to the broad-winged buteo old colloquial name is ferrugineous rough-leg, due to its similarity to the closely related rough-legged hawk (B.
lagopus). This species is a large, broad-winged hawk Class: Aves. Habitat Suitability Index Models: Ferruginous Hawk [Thomas M. Jasikoff] on *FREE* shipping on qualifying offers.
The results from the population inventory found that the population is low but stable compared to the inventory, however the population is still significantly low compared to numbers in the s. This signifies that there is still a lot of work to do to ensure a sustainable ferruginous hawk population.
AltaLink will continue to support. Ferruginous hawk fledgling success and nesting densities in southern Idaho and northern Utah were closely correlated with the cyclic black-tailed jackrabbit population.
However, in years of low prey abundance, ferruginous hawks will often switch from primary to alternate prey [. - The Ferruginous Hawk Inventory and Population Analysis Alberta Sustainable Resource Development, Fish and Wildlife Division Jan See publicationTitle: Biologist at Alberta.
Ferruginous hawks are the heaviest of all hawks. The upland buzzard of Asia is the only hawk that averages higher than the ferruginous hawk in terms of length and wingspan, but the ferruginous hawk is heavier. Ferruginous hawks mate for life. The same pair nests every year, till one of them meets death.
The Ferruginous Hawk is the largest Buteo species in North America, with a wingspan of nearly meters. It is an open-country species that inhabits grasslands, shrub-steppes, and deserts of North America, nesting in 17 states within the United States and 3 provinces in Canada.Study area.
We defined our study area as the townships in the state of Wyoming, USA, with centroids in the distribution of ferruginous hawks  or with records of breeding ferruginous hawks from state databases (Fig 1).A township is an approximately square, km 2 area delineated by the U.S.

In California, dispersal distances from natal sites to subsequent breeding sites ranged from 0 to 18 kilometers, mean kilometers (Woodbridge et al.
