Magpie-Jays Flocks Are Led by Females

Written by Bob Sundstrom

This is BirdNote.

A flock of jays is emerging at the forest edge. Their heads are blue and white, with a long, black crest curling forward.

As they glide out from the trees, the whole bird becomes visible — white bellies and blue backs. Their spectacular tails are about as long as the rest of their bodies. 

[White-throated Magpie-Jay calls]

They’re called White-throated Magpie-Jays, named for the long tail reminiscent of a magpie’s. Found in much of Central America, White-throated Magpie-Jay flocks are family groups led by a dominant female. They include a mate and several female offspring that bring food to the primary female and her young. It’s an example of cooperative breeding, when birds other than the parents help out to raise young.

Magpie-Jays have an astonishing vocal system. Male magpie-jays are the big talkers—each one may use more than sixty vocalizations.

Nearly fifty species of jays are found around the world. Each distinctive, each with its own complex society.

For BirdNote, I’m Michael Stein.
