Despite its striking markings of red, yellow, and black, the slow-moving Western Tanager is a surprisingly inconspicuous bird of the western forests.

The Western Tanager, Piranga ludoviciana, is a medium-sized American songbird. Formerly placed in the tanager family (Thraupidae), it and other members of its genus are now classified in the cardinal family (Cardinalidae).
The species's plumage and vocalizations are similar to other members of the cardinal family.
Adults have pale stout pointed bills, yellow underparts and light wing bars. Adult males have a bright red face and a yellow nape, shoulder, and rump, with black upper back, wings, and tail; in non-breeding plumage the head has no more than a reddish cast and the body has an olive tinge. Females have a yellow head and are olive on the back, with dark wings and tail.
The song of disconnected short phrases suggests an American Robin's but is hoarser and rather monotonous. The call is described as "pit-er-ick".
Their breeding habitat is coniferous or mixed woods across western North America from the Mexico-U.S. border as far north as southern Alaska; thus they are the northernmost-breeding tanager. They build a flimsy cup nest on a horizontal tree branch, usually in a conifer. They lay four bluish-green eggs with brown spots.
These birds migrate, wintering from central Mexico to Costa Rica. Some also winter in southern California.
