在非洲，这三个属都有大型成员，
鹰属以非洲黑雀鹰(Accipiter melanoleucus)为代表，
鸢属以黄嘴鸢（Milvus aegyptius）为代表。
鵟属以非洲鵟（Buteo Augur）和暗棕鵟（Buteo rufofuscus）为代表。
三者重量相似，都在1KG左右，但是地位却彼此大不一样。
非洲黑雀鹰内外战基本无战绩，面对侵略性物种埃及雁的夺巢行为时，几乎无可奈何，并且埃及雁对非洲黑雀鹰的繁殖造成了恶劣影响。
Egyptian geese are unable to build nests. Sometimes they will just lay their eggs on the ground, but they will also happily use the nests of other bird species. These nests might be abandoned, but not always; geese are capable of taking over nests by evicting the current occupants.
Unfortunately for the black sparrowhawk, their nests are just right for use by a goose. Usurpations of sparrowhawk nests by Egyptian geese are common; previous estimates suggest that around two thirds of sparrowhawk nest sites suffer harassment or usurpation by geese.
There is little a sparrowhawk can do to defend its nest. While an adult sparrowhawk is a fearsome sight to the doves and pigeons they prey upon, they are less than half the size of an Egyptian goose. Combined with the goose’s aggressive nature, fighting back is not a viable option; in most cases abandoning the nest is the sensible choice.
This harassment and usurpation of their nests takes its toll on black sparrowhawk breeding success; previous research has found that pairs breeding in territories where geese usurped nests produce an average of 0.76 chicks per breeding attempt, compared to 1.58 chicks for pairs breeding in goose-free territories.

对比之下，黄嘴鸢碰到埃及雁那是先宰了再说。

黄嘴鸢继承了Milvus属出色的空战能力，但拥有更大的爪子和更强的侵略性，这使得黄嘴鸢在内外战中表现不俗。

I was on a game drive in the Hluhluwe Umfolozi Game Reserve when I saw something in the distance – two big birds clashing in mid-air. The birds fell to the ground but I couldn’t see what had happened because the bush was too dense and the grass so high. My guide headed in the direction of the birds and a couple of minutes later we saw something on the road. We moved closer and could see a dead spotted eagle owl on the ground and a yellow billed kite feasting on it. The kite was so busy with the kill that we were able to get close to the scene and capture some pictures of the aftermath of a fight between these two large birds of prey.
很多人都下意识以为非洲没有鵟，这是错误的刻板印象
非洲鵟（Augur Buzzard）体重1kg左右，与暗棕鵟和阿彻尔鵟共同构成一个物种复合体。
是鵟属的特技飞行员，以捕食巨蜥和莫桑比克射毒眼镜蛇著称。
它拥有蹄兔狩猎场的优先划分权，对非洲鹰雕，吼海雕和猛雕，黑雕从不客气。
作为没有天敌的顶级掠食者，虽然成年个体年死亡率很低（4.8%，对比金雕是7%，大角鸮是9%），但是生育力也很低下，每年都只繁殖一只幼鸟。
非洲鵟抽猛雕
非洲鵟抽黑雕
很多人基本会被下意识认为是常规的“大猛禽不理会小猛禽的挑衅“，这次（1966年的老记录）直接是非洲鵟打劫体重是自己四倍多的黑雕
其实黑雕也不是啥好鸟，经常打劫和欺负更加懦弱的猛雕（我打不过鵟，难道还打不过你？）
另外提醒一下，非洲黑雀鹰是黑雕的猎物之一，尽管它的体重与打劫黑雕的非洲鵟相似
