“…Schmutz (1987Schmutz ( , 1989 found that Swainson's Hawks in southeastern Alberta had higher productivity in agricultural areas than in nonagricultural areas. In Oklahoma, Swainson's Hawks used habitat cover types, most of which were in grain agriculture, in proportion to availability (McConnell et al 2008). We found nest success and the number of young per nest were comparable between agricultural communities and desert scrub and grasslands.…”

“…Buteo hawks and other raptors partition habitat by nest substrate and land cover type (Bechard et al , McConnell et al , Kennedy et al ) in response to limited availability of nest sites in non‐forested habitats (Restani , Janes ). The flexibility of ferruginous hawks to nest on anthropogenic structures (Gilmer and Stewart , Bechard and Schmutz ) may, thus, be an adaptation to reduce inter‐specific competition for nest substrates.…”

Human‐made structures, vegetation, and weather influence ferruginous hawk breeding performance

Studies of anthropogenic impacts on wildlife may produce inconclusive or biased results if they fail to account for natural sources of variation in breeding performance and do not use probabilistic sampling at a scale functional for management. We used stratified random sampling and generalized linear mixed models to test hypotheses on relationships of daily nest survival rate (DSR) and fledgling production with anthropogenic and environmental factors that influence reproduction in the ferruginous hawk (Buteo regalis). We conducted the study across ferruginous hawk range in Wyoming, USA, 2010-2012. We performed extensive field surveys of prey, vegetation, and nest substrates, and used spatially explicit data to quantify weather, and the most widespread forms of anthropogenic infrastructure (i.e., roads, oil and gas well pads) in ferruginous hawk territories. We found strong evidence that DSR and productivity were greater for nests on anthropogenic structures (i.e., artificial nest platforms, gas condensation tanks, abandoned windmill platforms, power poles) compared to natural substrates (i.e., trees, cliffs, rock outcrops). Additionally, ferruginous hawks produced more fledglings at territories with greater shrub cover and fewer severe storms during the June brood-rearing period. Amount of oil and gas development and prey was not associated with either measure of breeding performance. Our results suggest that artificial nest platforms are an effective tool to improve breeding success of ferruginous hawks and nesting on anthropogenic structures does not constitute an ecological trap for this species. Although ferruginous hawks nested in some areas with very little vegetative cover, territories with greater amounts of shrub cover produced more fledglings. The negative impact of severe spring storms on fledgling production illustrates the importance of including future weather scenarios in management planning for this species because storms are predicted to increase in frequency and intensity as a result of climate change.

“…In general, nesting sites of Arctic-breeding raptors are associated with rugged terrain (e.g., cliffs), in areas that provide suitable micro-climatic conditions, e.g., south-facing slopes (Poole and Bromley 1988b;Wightman and Fuller 2005;Brambilla et al 2009;Peck et al 2018) with abundant prey (McConnell et al 2008;Booms et al 2010). Thus, we predicted topography would be associated with breeding habitat selection at all scales (landscape, home range, and territory; see Study design), likely through breeding and roosting behaviors (Poole and Bromley 1988a;Brambilla et al 2009).…”

Multi-scale selection models predict breeding habitat for two Arctic-breeding raptor species

et al. 2020

Raptors are important environmental indicators because they are apex predators and can be sensitive to disturbance. Few studies have addressed habitat preferences of tundra-nesting raptors, and those that exist have focused on fine-scale characteristics. With increasing economic development predicted to occur throughout the Canadian Arctic, the investigation of raptor breeding habitat at broad spatial scales is required. We modeled breeding habitat selection for two raptor species on north Baffin Island, NU, Canada. During aerial surveys conducted over six breeding seasons, we documented 172 peregrine falcon (Falco peregrinus tundrius) and 160 rough-legged hawk (Buteo lagopus) nesting sites. We used these locations in conjunction with remote sensing data to build habitat selection models at three spatial scales. Topography, distance to water, and normalized difference vegetation index explained selection at all scales; slope aspect was also important at the finest scale. To validate landscape scale models, we conducted a validation survey that resulted in the detection of 45 new nests (peregrine falcon n = 21, rough-legged hawk n = 24). We did not detect any new nests in areas where model-predicted occurrence was expected to be low. Conversely, we found more than half of previously undetected nests in areas where model-predicted occurrence was expected to be high.
