REYES AND WILLIAMS BIRDS OF IOWA. I 59 



Subfamily PARING. Titmice. 



Genus PARU3 Linn.i i b. 

 Subgenus LOPIIOPHANES Kaup. 

 [B 285, R 36, C 40, U731.] 

 Parus bicolor Linn. Tufted Titmouse. Northern Iowa, rare; cen- 

 tral Iowa, not common; southern Iowa, "abundant; resident through- 

 out the year." (Trippe). 



Subgenus PARES Lixn.eis 



[B 290, R 41, C 44, U 735-] 

 Parus atricapillus Linn. Chickadee. Resident; abundant. Nests 

 in cavities in stumps. Eggs, six to ten in number, but usually seven; 

 they are laid during the last week in April, or first in May. Not infre- 

 quently the nest is found at a height of ten or twelve feet from the 

 ground. During the cold months the chickadee is to be seen almost 

 every day — even in towns — but as spring approaches it retires to the 

 woods to breed, and is not often noticed unless especially sought for in 

 its favorite haunts. About the middle of September it again comes out 

 of the secluded woodland where it has passed the summer.

 and fall migrant. In the spring arrives a few days earlier than R. cal-

 appears to prefer the tops of forest trees, while its congener is usually 

 found in the small trees and bushes. In the fall it is found among the 

 low willows along the streams.
