Appearance:

Build like a Magpie, but slightly more slender. Black hood, white throat, buff body and beautiful azure-blue wings and tail. Unmistakable if seen well. In unfavorable conditions the long tail in combination with the black hood and contrasting pale throat is diagnostic. Sexes alike. Flight similar to Magpie, but less staccato and more decisive. Behaves more like a Jay than a Magpie, and usually moves about in small groups.

Sound:

Most typical call is a high-pitched, finch-like, rapidly ascending "hvrriit" (similar to some Siberian Jay or Jay calls). Has a rich repertoire various social sounds of which some are more Magpie-like, like a dry and rolling "krrrrrrr".
