The Pecking Order

It’s best to be the alpha bird

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.

The Pecking Order

Adapted from a script by Dennis Paulson

This is BirdNote.

[Dark-eyed Juncos chipping]

If you like drama, watch the juncos at your bird feeder. These small, brown birds will get quite feisty around food. You’ll see one bird come in to grab a bite, then another darts over and pushes the first bird off. Or two birds may have a little tiff, with their tails flared out. What’s going on here?

[Dark-eyed Juncos chipping]

Birds in flocks almost invariably develop a literal pecking order — or, as scientists call it, a “dominance hierarchy.” The term comes from studies of chickens, which found that there was an alpha chicken that could peck any other chicken in the flock. A beta chicken could peck all others except the alpha. And so on. Think of the poor omega chicken, all the way at the bottom!

[Hens clucking]

With juncos, we know that males are dominant to females, and adults are dominant to young birds. So, the next time you see a group of birds, pay close attention to the dynamics among them. Who’s the alpha, and who’s the beta? Can you spot the omega? Do the birds flock together or work apart?
