Perisoreus internigrans

Black-headed Jay, no subspecies.

Black-headed Jay usually moves alone or in pairs. When they move in pairs, they fly in a line in the woods, one in front of the other, not far from each other, and occasionally chirp to respond to each other. The chirping sounds like "ga-a, ga-a", with the first syllable being heavy and the second syllable being lighter. When flying in the woods, they usually fly in a straight line. Each flight distance is not far, and when they are startled, they fly far away.

The breeding season of Black-headed Jooks is from May to July. The nest is built on the branches at the top of the tree, 5-20 meters above the ground. The nest is mainly made of dead branches, with soft materials such as dead grass, plant fiber, bark, grass roots, hair, moss, feathers, etc. inside, and the nest is bowl-shaped. Nesting begins in March and eggs begin to be laid in mid-to-late April, with 2-4 eggs per nest. The eggs are sky blue or dark blue-green, with brown and gray-brown spots, especially denser at the blunt end. The male and female birds take turns to incubate the eggs, and the incubation period is 18±1 days. The chicks are late-maturing and are fed by both male and female parents. The nesting period is 26-30 days.
