橡子啄木鸟（Melanerpes formicivorus）在合作育种史上起着重要的作用。这是最早发现合作繁殖的物种之一，两个以上的个体在一个巢穴里觅食，并明显地分享配偶（Myers 1915; Leach 1925; Michael 1927）。随后，在他的经典著作《动物分散与社会行为的关系》中，维恩-爱德华兹（v.c. Wynne-Edwards）指出，这种物种储存橡子的习惯是鸟类评估食物供应和调整繁殖以避免过度开发资源的一种手段。事实上，Wynne-Edwards认为橡子储存是“一种疾病仪式的完美例子，它结合了橡子啄木鸟的样本：帮助筑巢，一夫多妻制，以及对可变橡子作物的依赖。
Th e acorn woodpecker ( Melanerpes formicivorus ) plays an important role in the history of cooperative breeding. It was one of the earliest species for which cooperative breeding was noted with more than two individuals feeding at a single nest as well as apparent mate-sharing (Myers 1915 ; Leach 1925 ; Michael 1927 ). Subsequently, in his classic Animal Dispersion in Relation to Social Behaviour , V. C. Wynne-Edwards singled out the acorn-storing habits of this species as a means by which birds assessed the food supply and adjusted their breeding so as to avoid overexploitation of resources. Indeed, Wynne-Edwards suggested that acorn storing was “the perfect example of an epideictic rite, combining as it does a sampling of the Acorn woodpeckers: Helping at the nest, polygynandry, and dependence on a variable acorn crop
