植物雌激素，主要是芒柄花素和染料木素，在干旱年份在发育迟缓的沙漠一年生植物的叶片中产生。当这些化合物被加州的鹌鹑摄取时，显然会抑制生殖，并阻止没有足够食物的幼鸟的生产。在多雨的年份，杂草生长旺盛，植物雌激素类物质基本上不存在。然后，鹌鹑繁衍后代，丰富的种子作物带着扩大的种群度过冬天。
Phytoestrogens, largely formononetin and genistein, are produced in the leaves of stunted desert annuals in a dry year. When ingested by California quail, these compounds apparently inhibit reproduction and prevent the production of young that will not have adequate food. In a wet year, forbs grow vigorously and phytoestrogenic substances are largely absent. Quail then breed prolifically and the abundant seed crop carries the enlarged population through the winter.
