Also by studying parental care, behavioural scientists can gain a useful window on the social dynamics of family groups, providing insights on sexual conflict (Chapter 9), parent–offspring conflict (Chapter 7), sibling rivalry (Chapter 8), and kin-mediated cooperation (Emlen 1994, 1997). And because hornbills aren’t especially formidable, they’ve evolved a very effective way to ensure they keep any cavities they find. To learn more, visit our Earning Credit Page.
