 pi. 2. ("Carolines . . . Florides et . . . pour patrie la Zone torride"=:Caro- 

 lina and Florida; cf. A. O. U. Check-list North Amer. Birds, ed. 3, 1910, 

 p. 153.) 



Characters. — Size large; light markings on undersurface of pri- 

 maries less extensive; wing J* (32 specimens) 414-445 (426); $ 

 (28 specimens) 414-438 (426). 



Resident from the mountains of northeastern Sonora (Sasabe, 

 Moctezuma), western Texas, eastern Oklahoma, southeastern Kansas, 

 Missouri, southern Illinois, southern Indiana, central Ohio (northern 

 Licking County), eastern West Virginia, and Maryland south to the 

 lower Rio Grande Valley in Texas (Brownsville), Louisiana, the 

 Gulf coast, and Florida. The breeding range in recent years has been 

 extended slowly along the northern boundary, with stragglers re- 

 corded casually to Nebraska, the Dakotas, and southern Ontario, 

 eastward to southwestern Quebec, Maine, and Nova Scotia. 



A male from Guadalajara, Jalisco, with the wing 415 mm., seems 

 to indicate that this large northern form extends south from the 

 international boundary through the plateau region of Mexico and 

 the adjacent mountain areas. In this same connection Col. L. R. Wolfe 

 has pointed out to me some interesting data concerned with egg size 

 in these birds. Three sets comprising 6 eggs in his collection from 

 La Laja, in northern Veracruz, on the coastal plain about 40 miles 

 south of Tampico, Tamaulipas, average 73.5 X 48.4 mm., which agrees 

 closely with an average of 74.3x50.1 mm. for 21 eggs in 11 sets in 

 the U. S. National Museum from Texas and Florida. As eggs of 

 the subspecies of true tropical range are smaller, as will be shown 

 under that race, there is indication that the northern form may range 

 into northeastern Mexico, though this requires check whenever skins 

 from that area may be available.
