[50][265] Occasionally, Cooper's hawks are known to hunt bats. [142] Interestingly, in the Manzano Mountains and Goshute Mountains, juvenile sharp-shinned hawks were roughly twice as numerous as juvenile Cooper's hawks but the number of adults seen passing through of the two species was roughly the same. [351] Native white pine (Pinus strobus) was preferred in Massachusetts, at 58% of 48 nests, and in Pennsylvania, at 78% of 18 studied nests, and the most used tree in a study from Wisconsin as well, at 35% of 82 nests. Pinkerton, M. E., Wellehan Jr, J. F., Johnson, A. J., Childress, A. J., Fitzgerald, S. D., & Kinsel, M. J. Bradley, C. A., Gibbs, S. E., & Altizer, S. (2008). Rosenberg, K. V., Kennedy, J. Here, the most frequently identified prey species was the Mexican Plateau horned lizard (Phrynosoma orbiculare) (11.5% of 191 prey items), followed by the northern flicker and thirdly the crevice spiny lizard (Sceloporus poinsettia) (10.47%, plus other unidentified spiny lizards making up a further 4.2% of the diet). [5] However, often the male does not perch far away, averaging about 765 m (2,510 ft), away from the nest during nesting to fledging stages, and occasionally as close as 120 m (390 ft). Greeney, H. F. & Wethington, S.M. [59] In Durango, reptiles were a pronounced part of the Cooper's hawk diet. [7][9] Despite declines due to manmade causes, the bird remains a stable species. [192][223] Flickers are common prey elsewhere as well, such as in Ithaca, New York. [45] Furthermore, juveniles can differ somewhat in size, tending to be slightly lighter and smaller than older birds, but not infrequently averaging longer in tail and especially wing length. However the sex ratio corrected over time in the urban area to an even amount, though it is still skewed outside the city (skewed broods towards males occur in cases where the females may become too costly to bring up, needing longer development stages and more foods). $9.50 Signature Sangria Cocktails Sangria-Tini Botanist Gin, Cointreau, Red Sangria, Sour, Prosecco, Fresh Citrus. [460] Synurbization has been detected in Cooper's hawks as, despite the dangers of various kinds of collisions, it has been found that in favorable urban areas, hawks of the species can seem to breed more closer to one another, gather more food and produce more young on average than those outside such areas. [22], No subspecies are recognized of the Cooper's hawk. Unidentified woodrats, at a mean estimated mass of 256.6 g (9.05 oz) were significant to the biomass of Cooper's hawks in northwestern Oregon. Cooper’s hawks are good-sized birds, distinctly smaller than a red-tailed hawk but about the size of a crow. [8] However, there are several known cases of adult eastern cottontails falling prey to Cooper's hawks, including cottontails estimated to weigh from 1,100 to 1,290 g (2.43 to 2.84 lb). [7][8], Like most related hawks, Cooper's hawks prefer to nest in tall trees with extensive canopy cover and can commonly produce up to two to four fledglings depending on conditions. Rough-legged hawks get their name because they have feathers on their legs that grow all the way down to their feet. [33] Numerous other tree squirrels are taken occasionally by Cooper's hawks. Rosenfield, R. N., & Bielefeldt, J. [2][176] Birds in general form about 50-85% of diet. [5][368], However, instead of the expected gradual recovery, in the 1960s to 1970s, the breeding success rate dropped, in almost certain correlation with man's use of chemical biocides, mostly DDT. Juvenile Cooper’s Hawk has yellow eyes 74% of ageable bird prey in this study were young of the year. [84] There are several cumulative records of Cooper's hawks also appearing in Cuba at times of migration but generally the species is still considered a vagrant rather than a regularly occurring species there. [2] More westerly Cooper's hawks (roughly west of the Rocky mountains) show slightly less pronounced sexual dimorphism than hawks of the species elsewhere. [186][217][218][219] Even smaller birds, the hummingbirds, are essentially immune to Cooper's hawks (due to their own extreme agility) and were seen to incidentally benefit from nesting close to the hawks in California, due to a low risk of predators approaching while the hawks are present. outside thrushes, corvids and icterids) tend to not be as large-bodied and, although by no means neglected, are seldom equal in overall dietary importance (biomass). With a range very similar to that of the Cooper’s Hawk, Red-shouldered Hawks can be found year-round only in all of New Jersey. & Bielefeldt, J. In the raptor guild within southern Michigan, the overall food breadth and size was studied against red-tailed hawks, red-shouldered hawks and American kestrels. Stout, W. E., Cassini, A. G., Meece, J. K., Papp, J. M., Rosenfield, R. N., & Reed, K. D. (2005). Thorington Jr, R. W., Koprowski, J. L., Steele, M. A., & Whatton, J. F. (2012). Lamberski, N., Hull, A. C., Fish, A. M., Beckmen, K., & Morishita, T. Y. [5][17][19][20] Genetic testing has indicated that the Cooper's hawk is quite closely related to the northern goshawk, with the similar superficial characteristics to the Cooper's of the sharp-shinned hawk, a close relative of the Old World sparrowhawk, apparently obtained through convergent evolution. Cava, J. There are also more great viewing sites right next door - click to see what New York has to offer during hawkwatch season! [59] In Terre Haute, Indiana, mourning doves and rock doves were 14% and 21% of the diet, respectively. Henny, C. J., Olson, R. A., & Fleming, T. L. (1985). Proudfoot, G. A. and R. R. Johnson (2000). [7][42][89] As with all Accipiters, Cooper's hawks can presumably only withstand a certain level of loss of habitat before an area becomes essentially unlivable. However, the sharp-shinned hawk nests in Missouri were at much higher elevations, i.e. Tail molt may generally start with the middle tail feathers, proceeding posteriorly to the upper tail coverts, also starting with the median feathers on the scapulars. [153][285] In southern Wisconsin, the food niche breadth was rather higher for the Cooper's at 6.9 and the mean prey mass, at 109.9 g (3.88 oz), was second only to the red-tailed hawk's. [93][50][94] Pine plantations are popular nesting sites across several parts of the range. [367] The clutch size averages anywhere from about three to five. Compared to the other two Accipiters, Cooper's have an intermediate amount of feathering at top of the tarsus, as well as intermediate relative middle toe length and eye proportions, but have relatively the longest tail and the shortest wings of the three. [62][397] However, the mean age at death recorded in 136 banded Cooper's hawks was 16.3 months. [7][42] However, all three species prefer fairly enclosed canopies over their nesting areas, i.e. [5] During hunts of rock doves (Columba livia) in urban areas, Cooper's hawks have been seen to engage in open air stoops to capture the prey. However, that inactivity could last up to 5 hours during heavy rainfall. However, the three longest distance movements from southern California were all northbound, i.e. (2015). Sometimes a younger sibling that has died from other means may be eaten by the siblings or by the parents. [416][417][418] A high balance of the bacterial disease Mycoplasma gallisepticum, common to birds who frequent bird feeders, was found in Cooper's hawks (transmitted from their prey) studied in Illinois (the highest of any six raptor species studied) however effective antibodies were found and no external infection was noted. [2][296] Data from Hawk Mountain Sanctuary shows that the Cooper's hawks has recovered from DDT more gradually than the sharp-shinned hawk here. The Red-tailed Hawk is New York’s most common hawk. Eastern gray squirrels (Sciurus carolinensis) were taken of up to adult size but fox squirrels (Sciurus niger) were only taken as juveniles, as the adults, sometimes scaling up to 1,350 g (2.98 lb), were apparently too formidable for the Cooper's. A. [118] Frequent aggressive interactions were recorded between females, often yearling and 2nd year vs older females. Adults have a rusty red tail. [7][447] Evidence from long-time migration counts at Bake Oven Knob show slight peaks at intervals of 3 to 4 years, however no dramatic declines have been detected since the 1980s. The Southwestern Naturalist, 56(1), 17-23. Ward, M. S., & Mannan, R. W. (2011). [48] Average weight of 104 male migrating hawks in Cedar Grove, Wisconsin was 342 g (12.1 oz) (with adults averaging 4% heavier than juveniles), whilst the average of 115 females migrants was 518 g (1.142 lb) (with adult averaging about 5.5% heavier than juveniles). [196] Numerous other corvids may be hunted, including most overlapping jays, as well as the Clark's nutcracker (Nucifraga columbiana), black-billed magpie (Pica hudsonius), possibly yellow-billed magpie (Pica nuttalli) and a few species of crow. Recent surveys indicate that populations are on the rise in New York… 12/28/2020. A., Causey, M. F., Mossop, D. H., Klucsarits, J. R., Robertson, B., Robertson, S., Mason, J., Maurer, M. J., Melvin, R. J., Dwason, R.D., Bortolotti, G. R., Parrish, J.W., Breen, T. F. & Bond, K. (2009). (1991). Later she produced an aberrant male with similar characteristics that successfully fledged. [33] Usually the male Cooper's hawk removes the head and viscera of prey before bringing it, then taking it to plucking stumps, although often the plucking is done right where prey is killed. they also have an outer toe that is reversible, which we will mention again below. Often, much like the northern goshawk, the displaying male flares his undertail coverts. [57][281] In Tucson, 70.8% of 48 nests were found to be non-native Eucalyptus trees. NH Conservation Status: Not listed Federal Status: Not listed; Cooper’s hawks are legally protected in New Hampshire. [136] At the hawkwatch in Cedar Grove, Wisconsin, the Cooper's hawk was not among the most regular species, being the 6th most frequently most recorded species. [411], An extremely high amount of Trichomoniasis was found in nestlings in southeast Arizona. [3][56][58][331][333] Mean distance between active nests in Illinois was 5.3 km (3.3 mi). [2] This species usually is considered monogamous. [5][62][474] However, as an opportunistic natural predator of almost any North American bird smaller than itself, the Cooper's hawk may inadvertently deplete populations of rarer, conservation-dependent species. [43] A different sample of Wisconsin Cooper's hawks reportedly averaged 327 g (11.5 oz) in males (sample size 60) and 580.3 g (1.279 lb) in females (sample size 57). [115] Cooper's hawks have been recorded as engaging in an exaggerated, nighthawk-like flight in non-courtship circumstances, such as during migration or by recent fledglings. Cooper's hawk was formally described by the French naturalist Charles Lucien Bonaparte in 1828 from a specimen collected near Bordentown, New Jersey.He coined the binomial name Falco cooperii. [179][188][217][245][246] Adult ducks and herons of roughly equal weight to Cooper's hawks and other largish adult water birds including ring-billed gulls (Larus delewarensis) and American coots (Fulica americana) are sometimes tackled by these hawks. Start your review of Cooper's Hawk Winery & Restaurant - New Lenox. [2] This species tends to be active earlier in the morning than sharp-shinned hawks and Eurasian sparrowhawks (Accipiter nisus) and is generally much more likely to be active in the morning than in the afternoon. This predator is known to consume vertebrate prey almost exclusively. Deal, E., Bettesworth, J., & Muller, M. (2017). [366] Younger forest in North Dakota was surprisingly preferred, with the average estimated age of trees used by Cooper's at 59.9 against a random tree age in the area of 74.6. [51][326][327] In Arizona, birds of each sex were found to usually pair with like-age individuals. [234] However, the bobwhite appears to be a secondary prey species in all known studies and there is no evidence that Cooper's hawk predation alone can deplete bobwhite populations, unlike causes directly contributable to man such as overhunting and habitat destruction. ### Bird sounds provided by The Macaulay Library of Natural Sounds at the Cornell Lab of Ornithology, Ithaca, New York. Smallwood, J. [222] In the more rural north Florida, again the mourning dove leads the prey selection, accounting for 16.5% of 1100 prey items. [334] Rather small areas may be defended where hunting occurs near the nest. In New York, the autumn hawk migration draws many bird watchers. [383] After they are about eight weeks old, they may start to hunt for themselves, but are usually still reliant on parents for food. [2] The first instance of non-piratical scavenging on carrion was recorded when a Cooper's hawk was seen eating at a white-tailed deer (Odocoileus virginianus) carcass. [5] In one case, an entire brood of 4 nestlings from 2.5 to 3.5 weeks old were found dead in the nest, apparently having died due to exposure after consistent heavy rains. [366] It was determined in Maryland that egg-laying and other mean dates rival or are even later than the longer distance migrating broad-winged hawk, and are much later in general than other Buteo hawks here. These birds had faded back color and lacking strong barring on the tail. [174] Medium-sized woodpeckers, such as red-headed woodpeckers (Melanerpes erythrocephalus) and red-bellied woodpeckers (Melanerpes carolinus) were important secondary prey in different parts of the range. [5][7][24] However, evidence based on genetic markers shows that westerly birds such those in British Columbia populations are genetically differentiated from those in the Upper Midwest, indicating that the Cooper's hawk were restricted to at least two Pleistocene glacial refugia with the Rocky mountains acting as a natural barrier to gene flow between hawks on either side while breeding. Against the barred underbody on adults, the wings are more or less flecked in similar color, with pale greyish flight feathers and a broadly white-tipped tail correspondingly barred with dark gray. [458] A similar translocation effort away from the Los Angeles basin around the Los Angeles International Airport translocated 349 Cooper's hawks (about a fifth of all translocated raptors), apparently successfully. You can find Osprey’s in New York during the spring and summer. [419] 91% of 47 tested adults in Wisconsin had Leucocytozoon toddi and 62% had Haemoproteus but only 12% of 33 nestlings there had parasites. [93] Data from Oregon showed that 74% hatched and 61.4-69% successfully fledged, a much lower rate of nest success than goshawks, at 90.4%, and, surprisingly, than sharp-shinned hawks, at 91.7%. Stout, W. E., Rosenfield, R. N., Holton, W. G., & Bielefeldt, J. About 5 species each of duck and heron, a dozen species of shorebird and a smaller assortment of grebes and rails are known in the prey spectrum. Carved from basswood and finely detailed with acrylic paints, each one is extremely lifelike from head to tail feathers. [7] While growth is slow for about three days, sexual dimorphism by size may begin by to be measurable by about seven days of age. [381][382] Due to the female usually only beginning incubation with the third egg, the first three eggs often hatch on the same day, while the fourth and fifth eggs often hatch one (rarely up to three) day later. [2][64] Most Cooper's hawks are considerably larger than most sharp-shinned hawks. [296], The average of 117 successful laid clutches was 4.18 eggs laid, 3.53 nestlings in successfully hatched clutches and 3.08 young in 26 successfully fledged broods in the Northeastern United States and southeastern Canada. [327] There was no strong differences in Wisconsin in clutch sizes between urban and rural locations. [218][258] Tree squirrels are widely taken but secondary prey for Cooper's hawks. [3] When large quadrupeds walk under the nest, the female may utter a semi-alarm call but does not leave the nest. Look up, and you’ll see evidence of nature’s persistence— in the form of pigeon feathers falling silently from the sky. Aldinger, K. R., Bakermans, M. H., Larkin, J. L., Lehman, J., McNeil, D. J., Tisdale, A., & Fearer, T. (2015). Juvenile Cooper's tend to have streaking or washing of tawny on the cheeks, ending in a light nuchal strip, giving them a hooded appearance unlike the capped appearance of adults (some juveniles, unlike adults, may manifest a slim supercilium as well). [47][188][179][217][218] The response of woodpeckers to a sighted Cooper's hawks varies, with evidence showing that downy woodpecker and flickers would behave more boldly and themselves may scold the hawk if part of a mixed flock but, if alone, the woodpecker will typically try to flee. The species may further make itself at home in some pure conifer forest, including the extreme southern part of the taiga but also in many parts of the west. [5][368] Regular natural causes of mortality in Cooper's hawk, mainly of their young, include hypothermia, windstorms and tree collapses. [2][101] In most parts of the range, Cooper's hawks have shown to be somewhat adaptive to all gradients of human development, including urbanized areas and can even nests in many cities. [205] In at least one case, a murder of American crows was observed to drive a Cooper's hawk to the ground and possibly seriously injure it, although the fate of the hawk was not certain. They can be found year round in most areas of the state, but may only be commonly seen during the summer in the far northern parts of New York. Common, widespread icterids such as red-winged blackbirds (Agelaius phoeniceus) and common grackles (Quiscalus quiscula) are fairly frequent prey for these hawks. Stephens, R. M., & Anderson, S. H. (2002). [422][423] Haematozoa infection rates were also higher in adults than they were in nestlings in Arizona. [286], The Cooper's hawk is usually a top predator in the daytime but is not immune from attack by other predators. Rosenfield R. N. & Bielefeldt, S. A. Find 22 listings related to Coopers Hawk Restaurant in New York on YP.com. They have a slightly disc shaped face that helps funnel sound to their ears. [37] The average weights of Cooper's hawks from Oregon was about 19.4% lower in males and 14.5% lower in females than those from Wisconsin but the Oregon hawks evidenced less seasonal variation in weight. [33] Females have what is often thought of as their own hunger cry, whaaaa, heard especially in poorer food areas, when the male appears. [184] Key to prey selection for Cooper's hawk is the availability and abundance of birds in a given region. [5][8][270][274][275] Unlike with reptiles, there is little evidence that the Cooper's hawk regularly hunts amphibians in any area, despite a few species being known in the prey spectrum. Lang, S. D., Mann, R. P., & Farine, D. R. (2019). During the breeding season, Cooper’s hawks inhabit deciduous, coniferous, and mixed riparian or wetland forests. [61] Breeding may begin as early as February in the southern part of range, but, for the most part, the breeding season is from April to July. [47][179][197][198][199] One black-billed magpie was caught and killed by a Cooper's hawk when attempting to mob the hawk. Wine Club Members can pick up their wines and enjoy their Member benefits at any opened locations. Therefore, less dangerous hawks such as Buteos are mobbed more vigorously than the more dangerous Cooper's. [7][56][96] Hunting hawks typically utilize forest edge, open woodland and fencelines and such while hunting. Their breeding range terminates just before the southern part of Gulf Coast states, south Florida, the southern tip of Texas and all but inland northwestern Mexico. [280] Furthermore, the nests of the Cooper's and goshawks were fairly evenly spaced, at about 1.6 km (0.99 mi) apart, indicating that they maintain exclusive territories (almost as if within the same species), while sharp-shinned hawk nests were closer to goshawk nests but in much denser habitats. [7][50][177][188] A lower diversity are taken of shrikes, larks, penduline tits, aegithalids, treecreepers, dippers, silky-flycatchers and longspurs. [8] One study unusually found no strong dimorphism in the foods selected by males and females. s and 83.1% for sharp-shins). [388] In addition to Tucson, other cases of successful breeding by pairs of immatures reported in varied areas such as Indiana and New York. Consider some binoculars or a spotting scope! Often, sharp-shinned hawk nests are lower in the trees and placed in much denser vegetation (often even the sharp-shins with their smaller frames themselves accidentally strike against branches while attempting to enter the nest), in order to hide the nest more sufficiently against predators. Lauren P. Chicago, IL. However, data shows that in North America, the Accipiters home range size corresponded to the birds’ body size, i.e. Often the nest is shallower in conifers (i.e. [401][403] 70.8% of diagnosed mortality for Cooper's hawks of yearling age or older in Tucson was from such collisions. [365] On the contrary, in the early 1990s (while the species was generally recovering), the species was considered to be “state-endangered” in New Jersey, with ongoing harmful effects found for poorly-regulated (or entirely unregulated) logging and land development within 40 to 120 m (130 to 390 ft) of active nests. all young or sometimes adult birds of prey are killed). The Cooper’s hawk is named for William Cooper, a New York scientist whose biologist son James Graham Cooper was the namesake of the Cooper Ornithological Society, which was founded in 1893 in California and operated until 2016. [47][50][179][188][189][190][191] The closest rival to the robin in being most widely taken as prey for Cooper's hawks may be the common starling (Sturnus vulgaris), a non-native bird in North America with mean weights when taken of 79 to 82 g (2.8 to 2.9 oz). Lake, L. A., Buehler, D. A., & Houston, A. E. (2002). [57] However, hawks nesting in urban areas of Arizona do not seem to vocalize less than their rural nesting counterparts. Ditchkoff, S. S., Saalfeld, S. T., & Gibson, C. J. [440] A particularly severe reduction in eggshell thickness was recorded in New York state, at an average of 19.02%. [7][362] Data shows that mean egg laying times in Wisconsin may be shifting earlier by up to 4–5 days in different years, but the current mean is 1.3 days. [5][7] Eggs may be discarded by the mother after hatching but those that never hatch are left in place. to receive email notification when we can ship wine to your state. [5] Most prey is killed by repeatedly kneading the talons, with the kneading sometimes going on even after death, although in some cases birds are plucked while still alive. Crossley, R., Liguori, J., & Sullivan, B. L. (2013). [33] Other on-foot hunting efforts, especially when chasing quail, have been detected as well. Rosenfield, R. N., & Bielefeldt, J. The species was named in 1828 by Charles Lucien Bonaparte in honor of his friend and fellow ornithologist, William Cooper. [2][31] The adult's underside shows a bit of whitish base color overlaid heavily with coarse, irregular rufous to cinnamon bands, though these narrow into marginal shaft streaks around the throat. Emslie, S. D., Speth, J. D., & Wiseman, R. N. (1992). [210][363] Similar shifts may be occurring in New York state as well. [179][189] The diets of the three species were also studied in the Chiricahua Mountains of Arizona. [46] At Cape May Point, New Jersey, weights were similar as in Wisconsin (although only hatching-year juveniles were apparently weighed), with averages of 339.2 and 347 g (11.96 and 12.24 oz) in two samples of males and 518 and 530.3 g (1.142 and 1.169 lb) in the two samples for females. [126] In British Columbia, many adults are non-migratory but juveniles do tend to migrate. [143] In central and southwestern Idaho, Cooper's hawk accounted for relatively few of the recorded raptors, i.e. [455] Most urban-related mortality for Cooper's hawks is likely to be collisions with manmade objects. They are a dark slate gray above with and orange banded chest. Tucson and Albuquerque). [163], When hunting bats, they can follow all twists and turns, and may succeed in capture in up to 90% of hunts. This video includes calls of adult and immature Cooper's Hawks. (2008). This can be both freshwater rivers and lakes or saltwater beaches. The Starling, Yellow-shafted Flicker, E. Meadowlark, Robin, and Common Grackle together constitute 87 per cent of the avian diet, with the Starling being by far the most frequent item on the menu. From appetizers to desserts, each dish on our menu is listed with a bin number to help guide you to your selection’s perfect wine match. FOOD OF YOUNG COOPER’S HAWKS AT ITEIACA, NEW YORK Soecies Number chipmunk and the red squirrel, which together make up 94 per cent of the mammalian diet during the nesting season. [475] However, there is no evidence that Cooper's hawk predation is one of the leading causes of kestrel declines and data seems to indicate it is, at most, a localized threat. They mainly feed on small mammals such as mice, voles, squirrels, chipmunks and rabbits. Wine Glass Collection. [2] In central New York, the male arrives in nesting woods by March, initially defending an area of 100 m (330 ft) or so. (1992). [2][5][91] For example, average distance from waterways away from nests in Wisconsin and Utah was 66.1 and 224 m (217 and 735 ft), respectively. [8][50][232][233] In Washington state, female Cooper's hawks took many California quails (Callipepla californica), which were estimated to constitute 47% of the prey selected by female hawks, but there was far too little impact overall to affect the quail's overall population. Johnson, J. [389][390] Considerable numbers of juvenile Cooper's hawks breeding may be historically associated with high turnover within populations. [7][293] Due to their threat level, the calls of great horned owls provoke a strong response from Cooper's hawks and banders and researchers usually utilize stimuli of great horned owls to attract a mobbing Cooper's hawks. [7] Their nest structure requires about 4.8 support branches. Osprey are always found near bodies of water that have abundant fish, since this is their main diet. [109], The Cooper's hawk is a typical Accipiter in all respects. [56][150] Flocking is not typically engaged in by raptors who migrate using powered flight, such as Accipiters, falcons and harriers, but many Buteo hawks do form loose flocks. A wide diversity of birds, considerably over 250 species, are known to be taken, constituting more than three-quarters of known prey species for these hawks. [7] An exceptionally pronounced case of this was in north Florida, where first year female home ranges went from up to about 932 km2 (360 sq mi) down to as little as 4 km2 (1.5 sq mi). [349] An unusual nest site in Wisconsin was on a grapevine. [23] A previously described subspecies, A. c. mexicanus, was discounted due to being weakly differentiated. [124] At regular western migration sites, the average difference of passage timing for Cooper's hawks of the earlier females and later males of like-age was five days. After some regional declines, a radiotagging study in Pennsylvania found that of 19 kestrels, 26% were killed by avian predators, with the suspected culprit in a majority of the cases being the Cooper's hawks. Often, state’s will put up several platforms designated for Osprey’s to aid in conservation and promoting good nesting sites. [2][133][135] Interestingly, the sharp-shinned hawk (despite the even more dimorphic migration times between sexes) showed no strong difference in distance on migration between the sexes, unlike female Cooper's which sometimes can move considerably further than males. Schafer, L. M., & Washburn, B. E. (2016). [211][212] Similar determent to the local nesting attempts of other small passerines such as warblers has also been reported. [1], Cooper's hawk was formally described by the French naturalist Charles Lucien Bonaparte in 1828 from a specimen collected near Bordentown, New Jersey. In general the relationship of the Cooper's and Gundlach's hawk is muddled and genetic testing indicated that it is possible (but not certain) that the Gundlach's may be insufficiently distinct to qualify as a separate species. [85] Canopy coverage is key to nesting Cooper's hawks, needing to be at minimum about 55-70%, averaging 55% in Wisconsin and 69.8% in Arizona.
