Ko specimens of this species were taken by either of the expeditions, 

 but I bring it into the present connection, since its liuown range is such 

 as to make it quite certain that it occurs in the Missouri region. It is 

 ail incouspicuous bird, liable to be long overlooked in regions where it 

 is not very abundant. 



I am unable to perceive any difference between American and Eu- 

 roi)ean examples, and 1 am not aware that any tangible characters have 

 been ascribed to our bird by those writers who have technically separ- 

 ated it. The Southwestern American form appears to constitute a slight 

 variety. 



The egg of the Creeper is not distinguishable with certainty from that 

 of a Chickadee, but is smaller, measuring only about 0.55 by 0.43. It is 

 white, speckled with reddish- brown.

This species is especially characteristic of the interior mountainous 

 regions of the West, although, to the southward at least, it reaches the 

 Pacific coast. It is reported from various parts of California, from Cape 

 St. Lucas, and from Mexico. Mr. Allen found it in Colorado, jMr, Mer- 

 riani in Utah, where it was abundant about White Sulphur Si)rings, Mr. 

 Holden in Wyoming, and Dr. Hayden states that it is numerous in the 

 "bad lands." I frequently saw it in Upper Arizona, in rocky fast- 

 nesses, where its peculiar song always attracted attention. Dr. Cooper 

 states that a nest from a wood-pile on the Upper Missouri was com- 

 posed of a loose flooring of sticks, lined with a great quantity of 

 feathers, and contained nine eggs of a reddish color, thickly spotted 

 with chocolate. He also found nests at San Diego, under tiled roo.;'s, 

 oontaniing young, in May. According to Mr. Ilolden, the nest is merely 

 a lew sticks and bits of moss put carelessly together : "one was placed 

 under a rock as large as a dog-house, and in it were four young ones,
