With an additional yellow spot on the throat, AUDUBON WARBLER supplants Myrtle Warbler in the West. It has all the mannerisms of its full brother the Myrtle and is perhaps even more adept at wing-flycatching. They are conspicuous and friendly birds in the western vallies during winter and Fisher states they are very abundant and more in evidence than any other bird in southern California.
During the breeding season they return to the firs and pines among the higher mountains where they enliven those gloomy recesses with a continuous flow of song, not loud but penetrating.
