Editing Harris's hawk (section)

===Feeding===
The majority of Harris's hawks' prey are mammals, including [[ground squirrels]], [[rabbit]]s, and larger [[black-tailed jackrabbit]]s (''Lepus californicus'').<ref name="HBW">{{cite book | last=Hoyo | first=Josep del | last2=Elliott | first2=Andrew | last3=Sargatal | first3=Jordi | title=Handbook of the Birds of the World: New world vultures to guineafowl | publisher=Lynx edicions | publication-place=Barcelona | date=1992 | isbn=84-87334-15-6 | page=}}</ref> [[Bird]]s from the size of small passerines such as [[diuca finch]] (''Diuca diuca'') to adult [[great egret]] (''Ardea alba'') and half-grown [[wild turkey]] (''Meleagris gallopavo'') can be taken.<ref name =raptor>Ferguson-Lees, James, and David A.

When [[Pack hunter|hunting in groups]], Harris's hawk can take large prey effectively, such as [[desert cottontail]] (''Sylvilagus auduboni''), the leading prey species in the north of Harris's hawk's range, usually weighs {{convert|800|g|lb|abbr=on}} or less.<ref>Bednarz, J.

Because it often pursues large prey, this hawk has larger and stronger feet, with long talons, and a larger, more prominent hooked beak, than most other raptors of similar size.<ref name= Hamerstrom/> Locally, other larger buteonine hawks, including the [[ferruginous hawk]], the [[red-tailed hawk]], and the [[white-tailed hawk]] also hunt primarily cottontails and jackrabbits, but each is bigger, weighing about {{convert|1200|g|oz|abbr=on}}, {{convert|1100|g|oz|abbr=on}} and {{convert|850|g|oz|abbr=on}},<ref name="HBW"/> respectively, more on average than a Harris's hawk.<ref>Smith, D.

In the Southwestern United States, the most common prey species (in descending order of prevalence) are [[desert cottontail]] (''Sylvilagus auduboni''), [[eastern cottontail]] (''Sylvilagus floridanus''), [[black-tailed jackrabbit]] (''Lepus californicus''), [[ground squirrel]]s (''Ammospermophilus'' spp. and ''Spermophilus'' spp.), [[Pack rat|woodrats]] (''Neotoma'' spp.), [[kangaroo rat]]s (''Dipodomys'' spp.), [[pocket gopher]]s (''Geomys'' and ''Thomomys'' spp.), [[Gambel's quail]] (''Callipepla gambelii''), [[scaled quail]] (''C. squamata''), [[northern bobwhite]] (''Colinus virginianus''), [[cactus wren]] (''Campylorhynchus brunneicapillus''), [[northern mockingbird]] (''Mimus polyglottos''), [[Sceloporus magister|desert spiny lizards]] (''Sceloporus magister''), and [[skink]]s (''Eumeces'' spp.)<ref>Mader, W.
