The Varied Thrush
(Ixoreus naevius)
By Don C. Fisher, Permanent Ranger
Among the uncommon birds of the park,
perhaps the varied thrush is entitled to a place. The varied thrush is
similar to the robin in size and shape, but it has a breast that is
colored a deep orange trimmed with a black band. The appearance of the
band suggests the existence of a collar. The back of the bird is a sort
of slate color.
The varied thrush loves the deep shade
of the hemlock forest and also dense fog and rainy weather. When the
heavy snow drives this bird from its favorite haunts, it migrates south
as far as Costa Rica for the winter.
The varied thrush's song has a clear
flute-like tone sometimes characterized by a rather mournful sound. The
sound is in keeping with the rather dismal choice of abode.
The time of breeding for the varied
thrush is late may and since the nest is built within the deep gloom of
a forest, visitors seldom find the nesting place. It is said that this
bird sometimes builds it nest on top of the old nest. This practice is
also commonly followed by the robin. The varied thrush is found largely
along the Pacific Coast from Southern Oregon to Alaska and while it is
typically a western resident it has been found occasionally in the New
England states.
A variety of names has been given to
this bird. The names as suggested are Alaska robin, Oregon robin,
Mountain robin, but the true name is varied thrush (Ixoreus naevius).
