The peculiarities iu the feathers of the under parts have already been ad- 

 verted to. This structure appears to be essentially connected with the red 

 feathers, since these have tlie same texture in the other species of the genus, 

 wlierever the color occurs. The remark may perhaps apply generall}' to the 

 red feathers of most, if not all, Woodpeckers, and may be connected with 

 some chemical or physical condition yet to be determined. 



Habits. Lewis's Woodpecker would seem to have a distribution through- 

 out the Pacific Coast, from the sea-shore to the mountains, and from Puget 

 Sound to the Gulf of California, and extending to the eastern border of the 

 Great Plains, within the limits of the United States. They were first ob- 

 served by ]\Iessrs. Lewis and Clarke, iu their memorable journey to the 

 Pacific. Subsequently Mi: Nuttall met with tliem in his westward journey, 

 in the central chain of the Eocky Mountains. This was in the month of . 

 July. Among tlie cedar and pine woods of Bear Eiver, on the edge of Upper 

 California, he found them inhabiting the decayed trunks of the pine-trees, 

 and already feeding their young. Afterwards, at the close of August, he met 

 them in flocks on the plains, sixty miles up the Wahlamet. He describes 

 them as very unlike Wood^ieckers in their habits, perching in dense flocks, 

 like Starlings, neither climbing branches nor tapping in the manner of their 

 tribe, but darting after insects and devouring Ijerries, like Tlirushes. He saw 

 them but seldom, either in the dense forests of the Columbia or in any set- 

 tled part of California. 



Towusend speaks of their arriving about the first of May on Bear Eiver 

 and the Columbia. Both sexes incubate, according to his observations. 



Dr. Gambel first observed this Woodpecker in a belt of oak timber near 

 the Mission of St. Gabriel, in California, and states that it was abundant. 

 He also describes its habits as peculiar, and unlike tlie generality of Wood- 

 peckers. Ur. Heermann, too, speaks of finding it in all the parts of Cali- 

 fornia which he visited. Dr. Newberry, in his Notes on tlie zoology of 

 Lieutenant Williamson's expedition, refers to it as most unlike tlie Cali- 

 fornia Wood])ecker in the region it occupies and in its retiring habits. He 

 describes it as seeming to choose, for its favorite haunts, tlie evergreen 

 forests upon the rocky declivities of the Cascade and Eocky Mountains. 

 He first oljser^ed it in Northern California, Init subsequently noticed it in 

 the mountains all the way to the Columbia. Tiiough often seen in low ele- 

 vations, it was e\-idently al[>ine in its preferences, and was found most fre- 

 quently near the line of perpetiutl snow; and when crossing the snow lines, 

 in the mountain-passes, it was often observed flying far above the party. He 

 describes it as being always shy, and difficult to shoot. 



Dr. S. W. Woodhouse describes this species as being common in tlie Lidinn
