Widmann — A Preliminary Catalog of the Birds of Missouri. 77 



breeding throughout its range, wintering from California and 

 the Gulf States southward to northern South America. 



In Missouri it may still be called a common transient visitant 

 spring and fall, though it is by no means as abundant as formerly, 

 when it was also well known as a summer resident, not only in the 

 prairie region of the north and west, but also in the Ozark border 

 region and even in the valleys of the Ozarks themselves. A 

 few may still breed in the state, as it is reported to do so at Apple- 

 ton City by Mr. C. W. Prier, 1906. Killdeers are among the 

 first migrants to return to us in earliest spring. The first reach 

 Missouri during the latter part of February (February 17, 1898, 

 St. Louis; February 18, 1902, Jasper Co.; February 26, 1904, 

 St. Charles Co.; February 28, 1904, Independence; February 

 28, 1893, Keokuk). The bulk of transients is with us from the 

 middle of March to the middle of April, and in fall from September 

 1 to the middle of November. Exceptionally late dates are 

 November 17, 1896, Keokuk; November 26, 1905, Jasper Co. 

 (Philo. Smith) ; and December 18, 1887, St. Louis.
