Chickadee. 



352a. Penthestes atricapillus septentrionalis (Harris). 

 Long-tailed Chickadee. 



Distr.: Central North America, from the Rocky Mountains and 

 Salt Lake Valley east to Minnesota, Wisconsin, and Iowa, south to 

 Kansas and New Mexico, breeding northward to the Mackenzie 

 region and Alaska (Kenai Peninsula). 



Special characters: Resembles P. alricapilliis, but tail longer than 

 wing (in P. atricapilhts the wing and tail are about equal in length) ; 

 tail feathers usually margined with white; the greater wing coverts 

 and tertials broadly edged with white. 



While the Long-tailed Chickadee has been taken in Iowa and 

 Wisconsin, it does not appear to have been observed in Illinois and 

 should be looked for in the northwestern part of the state. 



Messrs. Kumlien and Hollister say: "In late fall and winter typical 

 specimens of this form are taken in Wisconsin, even in the southern 

 part of the state, but n\ore often in the northwestern portion. A 

 number were taken near Hudson in November. We are unable to 

 say whether they are resident in that district, or merely winter vis- 

 itors." (Birds of AVisconsin, 1Q03, p. 124.)
