Birds in flocks almost invariably develop a pecking order. An alpha chicken can peck any other in the flock, and a beta chicken can peck all others but the alpha bird. Juncos and other small birds have a pecking order, too. The pecking order – or dominance hierarchy – of a flock of birds is usually this: males are dominant to females and adults are dominant to young birds. As a flock changes and birds come and go, the pecking order changes. If you feed backyard birds, you will likely notice this pecking order behavior in the flock.
