This is not uncommon in the Trinity Valley, seeking its food on the tall pines. The male is easily distinguished from the female by the red band of feathers at the base of the cranium.

These I observed in the coast range of mountains west of Santa Clara. It inhabits the evergreen oak-groves, Quercus densifolia. Taken in October (female). 11. ClNCLUS AMERICANUS, Sw. I have only seen this remarkable bird in the head waters of Trinity and Scott's Rivers at California. It is constantly seeking its food amongst the boulder rocks in the rivers, or on the shallows amongst pebbles ; sometimes wading, diving or swimming, and at other times flying from rock to rock. I have often watched them, and always felt a sort of amusement at their restless and singnlar movements. San Francisco, Nov. 18th, 1857. 2.
