“…This finding is consistent with a study involving translocation of red-tailed hawks in Illinois (Pullins et al 2018). Raptors exhibit high site fidelity during breeding and migration periods (Rosenfield andBielefeldt 1993, Preston andBeane 2009), a factor that could result in older birds being more likely to return to an airport than younger hawks.…”

Wildlife-aircraft collisions (wildlife strikes) pose a serious safety risk to aircraft. Raptors (i.e., hawks and owls) are one of the most frequently struck guilds of birds within North America. Integrated wildlife damage management programs combine a variety of non-lethal and lethal management tools to reduce presence of raptors on airports. Live-capture and translocation away from an airport is a commonly used non-lethal method to reduce the risk of raptor-aircraft collisions. In southern California, USDA Wildlife Services airport biologists live-captured, marked with auxiliary markers (i.e., airport program-specific plastic leg band), and translocated approximately 1,232 raptors from seven airports and military bases located within the highly urbanized environment of the Los Angeles Basin during January of 2010-December of 2016. Ten different raptor species were marked and relocated during this effort. The composition of translocated raptors was red-tailed hawks (38.9%), Cooper's hawks (27.5%), American kestrels (20.7%), barn owls (7.4%), and great horned owls (3.7%). Overall, the percentage of translocated raptors that returned to an airport was 11.1%. Although research is needed to better understand and increase the efficacy of such management efforts, this non-lethal method of reducing the presence of individual raptors at airports in southern California will be an important component of future wildlife management programs.

“…In contrast to Sharp‐shinned Hawks, locations where banded Cooper’s Hawks were recorded were more widely distributed and most encounters during the migration season were birds found dead near human settlements. Breeding season records come from Minnesota and Wisconsin (Rosenfield et al 2019a,2019b).…”

“…Cooper’s Hawks are regularly recorded during the migration and non‐breeding seasons in Costa Rica and Panama (Porras Peñaranda et al 2004, McCrary and Young 2008, Rosenfield et al 2019b). Combining band recovery and observation records with our data, the round‐trip migration for some of these birds may be > 10,000 km.…”

Accipiterhawks of the Laurentian Upland and the Interior Plains undertake the longest migrations: insights from birds banded or recovered in Veracruz, Mexico

Bird banding has allowed us to understand diverse aspects of the life histories of migratory raptors. However, most banding stations are located at northern latitudes so what we know about the movements of these raptors is biased toward higher latitudes, primarily from Canada and the United States, leaving important gaps in our knowledge of their movements at lower latitudes. Our objective was to describe the migratory movements of Sharp‐shinned (Accipiter striatus) and Cooper’s (A. cooperii) hawks based on banding and recapture records of birds that migrate through Veracruz, Mexico. More specifically, we sought to determine their breeding, migration, and non‐breeding locations, estimate their migration distances, and contribute to a better understanding of their migration patterns. With a total of 80 records, we calculated migration distances and used Kernel Density Estimation analyses to identify where these hawks were recaptured or recovered by season. The distribution of recaptures and recoveries largely coincided with breeding locations in the Laurentian Upland and the Interior Plains physiographic regions. All migration records follow a trajectory that extends from the midwestern United States to the Gulf coastal plain of Mexico. The mean breeding season migration distance to Veracruz was 3374 km (a difference of 27 degrees of latitude) for Sharp‐shinned Hawks and 2926 km (a difference of 25 degrees of latitude) for Cooper’s Hawks. Our non‐breeding records indicate that populations of Accipiter hawks from these North American populations migrate the longest distances to reach Central America, the southernmost distribution of their migratory populations. Distances covered by both species represent round‐trip migrations that may be as long as 10,000 km. Our results support those of previous studies and illustrate how continental physiography influences the migration routes, migratory behavior, and migratory connectivity of these hawks.

“…The Cooper's Hawk (Accipiter cooperii) is a common woodland hawk that often focuses on birds as prey (Rosenfield et al 2019b). While it nests throughout the United States and boreal Canada in a variety of tree species in dense woods (Rosenfield et al 2019b), in recent decades it has adapted to urban habitats ). Cooper's Hawks in more urban environments differ in behavior and nesting habitats (Mannan and Boal 2000, Estes and Mannan 2003, Stout et al 2007, Chiang et al 2012, Millsap 2018.…”

In recent decades Cooper’s Hawks have successfully colonized urban landscapes, where there may be ample prey but also a greater prevalence of disease in their prey. We searched for nesting Cooper’s Hawks in and around Berkeley, California, from 2002 to 2010, locating 95 nests, 89 of which successfully fledged at least one nestling. On average, each nest produced 3.6 fledglings. We evaluated the possible effects of the protozoan parasite Trichomonas gallinae on Cooper’s Hawk reproduction from the proportion of potential prey items brought to Lindsay Wildlife Experience that tested positive for the parasitic disease. We did not find a correlation between T. gallinae in potential prey species and nest success (i.e., if the nest fledged any offspring) or reproductive success (i.e., number of fledglings produced). Similarly, we did not find a relationship between reproductive success and distance to parks or percent of impervious surface within 500 m of the nest. The high reported rates of reproduction and high densities of Cooper’s Hawk in Berkeley and neighboring Albany suggest a robust population, and we did not find evidence that T. gallinae influences its reproductive success.
