northward in March and April and return in October and November. Miss H. E. 

 Colfax reports its occurrence in Porter County, June 8, 1884. 



297. Regulus calendula (Linn.). KUBY-CROWNED KINGLET. 



Common migrant; not so numerous as the species last mentioned, and also 

 arrives later. The immature birds remain after the old ones have gone. I always 

 associate them with the blooming of apple trees, about which they are often seen. 

 They sometimes remain in the southern part of the State until May 10. Miss H. 

 E. Colfax also reports this species in Porter County, June 8, 1884. They pass 

 south in September and October. 



SUBFAMILY POLIO PTI LI N^E. GNATCATCHERS. 

 GENUS POLIOPTILA SCLATER, 



Head of Blue-gray Gnatcatcher, nat. size. 



*298. Polioptila caerulea (Linn.). BLUR-GRAY GNATCATCHER. 



Abundant summer resident southward, not so common northward, and in some 

 localities not found. Arrive from the South March 3 1st to April 15th ; are usually 

 paired upon arrival and at once proceed to construct their nest. The nests are cov- 

 ered with lichens, and the inside composed of fine fibre and spiders' web, making 

 a very beautiful specimen of bird architecture. They have been reported from 

 Starke County " breeds," ( G. Frean Morcom ; H. K. Coale ); Dekalb, ( Mrs. Jane 

 L. Hine ); Porter, "summer resident," ( J. W. Byrkit ); Allen, "rare," ( C. A. Stock- 

 bridge ); Lake, breeding, ( G. F. Clingtnan). They leave for the South in October. 

 They are noisy little birds, who spy the intruder from afar and, like the Tufted 

 Titmouse, continue their chatter until he has left the neighborhood of their home. 

 They usually build their nest in the fork of a limb of some rough-barked tree in 

 the more open woods. The nest, owing to its resemblance to a lichen-covered knot, 

 is hard to find.
