along our southern border will probably reveal its presence as 

 a rare summer resident in the valleys leading up from the south. 

 The species has been observed by Mrs. L. McG. Stephenson at 

 Helena, Ark., and by Mr. Philo W. Smith Jr., at Eureka Springs, 

 Ark. 



*604. Spiza AMERICANA (Gmel.). Dickcissel. 



Emheriza americana. Fringilla americayia. Euspiza americana. Black- 

 throated Bunting. 



Geog. Dist.— United States east of Rocky Mountains, north 

 to Massachusetts, southern Ontario, Michigan, Wisconsin, 

 Minnesota, North Dakota; now extinct east of Alleghany 

 Mountains; breeds from Alabama, Mississippi, Texas, northward 

 and winters south of United States, migrating through New 

 Mexico, Arizona, Mexico (both coasts) and Central America 

 to Columbia and Trinidad. 



In Missouri a common summer resident in the prairie and 

 Ozark border regions; rare in the Ozarks where only in open, 

 long settled localities; sparingly on the cultivated ridges of the 

 southeast. The first arrive nearly throughout the state during 

 the fourth week of April, at least the forerunners do, impatient 

 males which want to reach their old haunts before rivals arrive. 

 Females do not appear before the first week in May, and the 

 great mass of the species, including the young of last year, comes 

 only during the second week of the month. Transients may be 

 seen flying over in the early morning from the last days of April 

 to May 20, some following the prairie region going east, others, 

 coming from the south, cross the heavily wooded part of Missouri 

 in a northerly direction. The first brood is able to take care 

 of itself by July 1, but we sometimes see parents feeding young 

 after the middle of August. When the breeding season closes, 

 families gather into small flocks and are seen flying south in the 

 early hours of the day from August 20 to September 10. To 

 the general observer the species is rare after the middle of Sep- 

 tember, but for one who knows the roosts the last has not gone 

 before the first of October.
