In northern California, mourning doves were the main prey species, making up 25.6% of 1057 prey items. There is even evidence that bluebirds have perceived the change in preference of Cooper's hawks to more profitable prey such as doves in developed areas and show less inhibition to the hawk’s presence. In the more rural north Florida, again the mourning dove leads the prey selection, accounting for 16.5% of 1100 prey items. Another popular prey family is the woodpeckers. A rather numerous and widely distributed species, the northern flicker ("Colaptes auratus"), is a particular dietary staple of Cooper's hawks, being about the third most widely reported prey species. The flicker was the main prey in northern New Mexico, at 22.5% of 316 prey items, and in southern Wisconsin, at 22% of 77 prey items. Flickers are common prey elsewhere as well, such as in Ithaca, New York. 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. In South Carolina, it was found that 15% of the red-headed woodpeckers in a study population were killed by hawks. All told, about 20 species (almost all in North America but for a couple poorly-studied species) of woodpecker are known to be taken, ranging from the smallest, the downy woodpecker ("Picoides pubescens"), to the largest, the pileated woodpecker ("Dryocopus pileatus"). 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. Despite the regularity of predation of woodpeckers that are in the open, a study in British Columbia shows indicated Cooper's hawks seldom prey upon woodpecker nests, perhaps due to being unable to access their secluded, smallish nest holes, with the study showing that the most regular predators of such nests were various mammals (from deermice to bears). Certainly the most controversial aspect of the Cooper's hawks are their predations upon galliforms. By far the most regularly selected types are New World quails.
