Editing Harris's hawk (section)

===Breeding===
They nest in small trees, shrubby growth, or cacti. The [[bird nest|nests]] are often compact, made of sticks, plant roots, and stems and are often lined with leaves, [[moss]], bark, and plant roots. They are built mainly by the female. There are usually two to four white to blueish-white [[bird egg|eggs]] sometimes with a speckling of pale [[brown]] or gray. The nestlings start light buff, but in five to six days turn a rich brown.<ref name=baicich1997>{{cite book |last1=Baicich |first1=Paul J. |last2=Harrison |first2=Colin J.

Very often, there will be three hawks attending one nest: two males and one female.<ref name=Kenn>{{cite book |last=Kaufmann |first=Kenn |title=Lives of North American Birds |year=1996 |publisher=Houghton Mifflin Company |isbn=978-0-395-77017-7 |url=https://archive.org/details/livesofnorthamer00kauf }}</ref> Whether or not this is [[Polyandry in animals|polyandry]] is debated, as it may be confused with backstanding (one bird standing on another's back).<ref>{{cite book |last=Ligon |first=J.

The eggs hatch in 31 to 36 days. The young begin to explore outside the nest at 38 days, and [[fledge]], or start to fly, at 45 to 50 days. The female sometimes breeds two or three times in a year.<ref name=baicich1997/> Young may stay with their parents for up to three years, helping to raise later broods. Nests are known to be predated by [[coyote]]s (''Canis latrans''), [[golden eagle]]s (''Aquila chrysaetos''), [[red-tailed hawk]]s (''Buteo jamaicensis''), [[great horned owl]]s (''Bubo virginianus''), and flocks of [[common raven]]s (''Corvus corax''), predators possibly too formidable to be fully displaced by Harris's hawk's cooperative nest defenses. No accounts show predation on adults in the United States and Harris's hawk may be considered an [[apex predator]], although presumably predators like eagles and great horned owls would be capable of killing them.<ref>Dawson, J.
