ANDERSON — THE BIRDS OF IOWA. 375 



of May, but I have found young birds in the nest early in July,- 

 in Winnebago, so two broods are probably reared. The usual 

 note of the bird is the familiar chick-a-dee , but in the springtime 

 they frequently utter a clearly-whistled pec-zve-o note, much like 

 the Phoebe's note. 



341. (735a). Parus atricapilhLs scptentrionalis (Harris). Long- 



tailed Chickadee. 



This is a Western form, best developed in the upper Missouri 

 and Rocky Mountain region, averaging larger, with tail longer, 

 rather exceeding wing in length, and wings and tail more con- 

 spicuously white-edged; average measurements: length 5.25- 

 5.50; wings 2.50-2.75; tail 2.60-2.80. This is probably the com- 

 mon form in western Iowa, the most eastern record in the state 

 being a specimen in my collection taken at Iowa City, Johnson 

 county, (identified by Robert Ridgway). 



County records: Fremont — "nesting" (Norris H. Reed, 061., 

 vii, 9, 1890, p. 142). Johnson — Shot one male at Iowa City, De- 

 cember 30, 1899 (Anderson). Mitchell- Winnebago — "breeding" 

 (Ridgway, Birds N. and Mid. Amer., iii, p. 400). Pottawattamie 

 and Mills — "common resident; breeds" (Trostler). Polk — "com- 

 mon resident; nests. I have no specimens now. They are a trifle 

 larger than the common form [which also occurs in Polk count}-] 

 and have a longer tail. I looked them up at the time and they 

 corresponded to the description given by Coues" (Johnson). 

 Sioux — "summer resident; shot a pair near Hawarden, in 1890, 

 which I think were this form; they had all the earmarks, any- 

 way" (Berrj^). Woodbur)- — R. Ridgway identified four speci 

 mens, Mus. Nos. 17,609-11-12-18, all taken at Sioux City, in 

 December, as septentrionqlis. Eleven other specimens taken at 

 Sioux City in December average about the same in measurements 

 (Anderson). 



342. (736). Parns caroli7icnsis And. Carolina Chickadee. 



The only Iowa record of this small Southern species is a speci- 

 men which I have examined, from the collection of Geo. H. Berry 

 of Cedar Rapids. He shot the bird at Keokuk, Iowa, May 4, 

 1888. It measures: h. 4; W. 2.38; T. 2.06. The specimen in 

 general appears very much smaller than the common Chickadee, 

 quills, tertials and rectrices with very indistincl whitish edgings,
