IV. SHOWN CREEPER. 



Certhia familiaris americana (BONAP.). 



Winter sojourner; common in the eastern portion of 

 the State; rare westward. Leave the last of March to 

 the first of April; begin to return in October. 



HABITAT. Temperate eastern North America; west 

 to the Great Plains (represented westward in the Rocky

Iris brown ; bill dark brown, with base of under flesh
