When using a prior years nest, the female reportedly selects and repairs it.  Most urban-related mortality for Cooper's hawks is likely to be collisions with manmade objects.  In Indiana and Illinois, mortality from collisions were somewhat more prevalent in Cooper's hawks than in sharp-shinned hawks but instances of predation on immature sharp-shins were three times more prevalent than predations on immature Cooper's. However, some other non-raptorial birds may have similar muscularity relative to their mass, such as the Canada goose (Branta canadensis) and even pied-billed grebes (Podilymbus podiceps), and these ample muscle masses may be correlated with migratory (rather than hunting) behavior.  Their nest structure requires about 4.8 support branches. Hanebrink, E. L., Posey, A. F., & Sutton, K. B.  The culmen may measure from 11.7 to 17.5 mm (0.46 to 0.69 in) in males, averaging about 16 mm (0.63 in), and from 17.5 to 23 mm (0.69 to 0.91 in) in females, averaging about 19 mm (0.75 in). Up close, they have a distinctive face for a hawk, that many think looks more like an owl.  Numerous other tree squirrels are taken occasionally by Cooper's hawks.  In Lansing, Michigan, evidence has been found of individual Cooper's hawks being annually devoted to the same wintering grounds, presumably due to their high quality.  In the Goshutes mountains, migrant male goshawks overlapped with female Cooper's hawks only in the length of the tail and the tarsus, with the body mass especially being quite distinct. Palleroni, A., Hauser, M., & Marler, P. (2005). (1938). Furthermore, females of all ages tend to migrate sooner and spend longer in winter quarters than like-age males, the latter staying relatively north and traveling back again earlier.  Generally, Cooper's hawks can be considered secretive, often perching within the canopy, but can use more open perches, especially in the western part of the range or in winter when they may use leafless or isolated trees, utility poles or exposed stumps.  Down first becomes deep and fluffy around two weeks, the following week first feathers among dense down, feather production accelerates but growth slows in the fourth week after which both increase for the fifth week. Aldinger, K. R., Bakermans, M. H., Larkin, J. L., Lehman, J., McNeil, D. J., Tisdale, A., & Fearer, T. (2015).  In northern California, mourning doves were the main prey species, making up 25.6% of 1057 prey items. After 2 weeks, she may begin to make "half-hearted" dives at the climber. The eye color of these hawks changes from bluish-gray in nestlings to yellow in young adults.  Only 2 to 3 food deliveries daily are usually necessary during incubation but the male has to hunt constantly once the young are large, rarely plucking and no longer decapitating prey. In the fall, they can collect in huge flocks called “kettles” on their way south.  The only confirmed accipitrid that Cooper's hawk have been known to prey upon is their smaller cousins, the sharp-shinned hawks. The most common chipmunk prey in Oregon is probably the 89.3 g (3.15 oz) Townsend's chipmunk (Neotamias townsendii) but the Cooper's hawks may take chipmunks down to the size of the 48 g (1.7 oz) least chipmunk (Neotamias minimus). 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.  Recent cases of cyanide poisoning of Cooper's hawks have been reported.  As in many birds of prey, the male is smaller than the female. von Dohlen, A. R., Scott, D., Dubey, J. P., & Lindsay, D. S. (2019).  Cooper's hawks are known to be vulnerable to West Nile virus with some regularity but sometimes are able to survive despite the viral antibodies being found. As an Amazon Associate we earn from qualifying purchases.  Studies in Arizona determined that heavily grazed agricultural areas were favored over lightly grazed ones due to greater prey concentrations in the latter habitats.  Only one breeding male in both Victoria, British Columbia (579 sample size) and in Albuquerque (sample size 305) were yearling while 4.8% of 123 in Milwaukee were yearlings (92% of which were paired with an adult female). All told, nearly 30 species of reptile may be hunted by Cooper's hawks. However, in the Oregon data, the number of eggs hatched was higher in Cooper's at 74% than in sharp-shinned hawks, at 69.4% (but not than the goshawk's). Lauren P. Chicago, IL. , Like a majority of diurnal birds of prey in the Northern Hemisphere, the Cooper's hawk is a partial migrant. Furthermore, even ornithological writings from these times reveal a strong bias against the hawks for their hunting of admired small birds. The 8 species of hawks found in New Hampshire are the Broad-winged Hawk, Red-tailed Hawk, Northern Goshawk, Rough-legged Hawk, Northern Harrier, Sharp-shinned Hawk, Cooper’s Hawk, and the Red-shouldered Hawk. A Red-tailed Hawk surveying it’s territory at Madison Square Park. Dunne, P., Sibley, D., & Sutton, C. (1988). They are on the small side with brown barring. Start your review of Cooper's Hawk Winery & Restaurant - New Lenox. (1998). (2018).  Most Cooper's hawks reacted to heavy persecution by behaving with more shyness and elusiveness. Among 151 prey items there, mourning doves were 20.5% by number and 27.5% of the biomass, Inca doves (Columbina inca) were 18.5% by number and 12.2% of the biomass and white-winged dove (Zenaida asiatica) 17.2% by number and 27.1% of the biomass.  The higher pitched calls of the young may even extend to females nesting within their first year while still in immature plumage.  Also, the sharp-shinned hawk appears to hunt more so birds that dwell at the canopy level in the woodlands (as opposed to ground to shrub height-dwelling birds) within the forest and prefers to attack in heavier cover than the Cooper's seemingly.
