DENDROICA CORONATA HOOVERI McGregor 



ALASKA MYRTLE WARBLER 



HABITS 



The Alaska myrtle warbler is another subspecies that was described 

 many years ago but only recently admitted to the A. O. U. Check-List. 

 Richard C. McGregor (1899) described this warbler, from specimens 

 collected in California, as a western race and named it for his friend 

 Theodore J. Hoover, who collected the type and placed his material 

 at his disposal. He called it Dendroica corOTiata hooveri^ Hoover's 

 warbler. In his description of it he says that it is "in colors and 

 markings like Dendroica coronata^ but with wing and tail much 

 longer." His table of measurements shows that the wings of Cali- 

 fornia males average .15 inch longer than those of eastern birds, and 

 the tails .14 inch longer, less than i/^ inch ! Among the wing measure- 

 ments of eastern males the individual variation is as great as the 

 difference in his averages, the shortest measuring 2.80 and the longest 

 2.95 inches ! It appears to be a quite finely drawn subspecies. 



Dr. Oberholser (1938) says of it: "The Myrtle Warblers breeding 

 in Alaska are recognizable as a western race of this species. They 

 differ from the eastern bird in larger size and more solidly black
