PR'ID.K — THE WoulU'EOKKUS. 545 



Mr. Audubon assigns to it the same distrihution, but is only able to give 

 the iuforinatiou in regard to its habits which he derived from the observa- 

 tions of Mr. Xuttall, which, however, do not correspond with those of Dr. 

 Cooper. Mr. Nuttall states that this species, seen in the forests of the Co- 

 kimbia and the Blue Mountains, has most of the haliits of the common Red- 

 headed species. He concedes that it is less familiar, and that it keeps gen- 

 erally among the tall hr-trees, in the dead trunks of which it burrows out a 

 hole tor a nest, sometimes at a great elevation. On approaching one that 

 was feeding its young in one of these situations, it uttered a loud reverber- 

 ating < Vr, and seemed angry and solicitous at his approach. He adds that 

 this species also inhabits Calitbrnia, as well as the northwest coast up to 

 Nootka, and that it is found eastward as far as the central chain of the 

 Eocky Mountains. An egg taken from a nest which contained four was 

 1.25 iu length and .75 of an inch in breadth. It \\as smooth, equally 

 rounded at both ends, thougli somewhat elongated, and pure white. 



We are confident that there must l)e some mistake in this statement. 

 The disproportion between tlie length and the breadth is unprecedented. 

 Even in the most oblong egg there is rarely so mucli as twenty-five per cent 

 difference. 



Dr. Cooper, in his Birds of California, speaks of it as rather a northern bird, 

 having seen none south of Santa C'lara., and there only in the mountains of 

 the Coast Itange in early spring. 



Dr. Heermann found this form not at all rare in the Sierra Nevada Moun- 

 tains, and occasionally met a stray one among the valleys. Their call-note 

 was similar to the cry of a child in distress, and was very disagreeable. 

 In their quick, restless motions, and their untiring diligence in quest of food, 

 they resemble the rest of the Woodpecker family. 



It was noticed by Mr. Eidgway only on the Sierra Nevada, and he is not 

 certain that he saw it on the eastern slope of that range.
