The Pecking Order: Dominance Hierarchies in Birds

Summary

This episode—which is Number 48—is about the “Pecking Order” in birds. Or, to use the more technical term, dominance hierarchy.

Our focus will be on dominance hierarchies that we see among birds within a single species. White-crowned Sparrows beating up on other White-crowned Sparrows, for example, as opposed to White-crowned Sparrows beating up on another species, like Lincoln’s Sparrow. The latter would be an example of interspecies dominance. But today, we’re talking about intraspecies dominance. Meaning within species.
