Harris Birds of the Kansas City Region. 225 



1916. There can be no question of the identification in this case, 

 as the birds were close enough to show their distinctive charac- 

 teristic, the sharp middle tail feathers a few inches longer than 

 the others. 



The older river men state that this bird was not uncommon in 

 the days when the river was filbd with refuse from the packing 

 houses. 



STERCORARIUS LONGICAUDUS Vieillot. Long-tailed Jaeger. 

 Accidental visitant. 



A specimen of this bird was taken at Bean Lake in the spring 

 of 1910 (Holland). On October 3, 1916, Mr. B. F. Bush Watched 

 two of these easily identified Jaegers worrying a bunch of Blue- 

 winged Teal on the Missouri River near Courtney. Mr. Bush is 

 a trained scientific observer and there can be no question as to 

 this record, especially as the birds were within a few feet of him 

 part of the time. These are the only known records for Missouri. 



Family LARIDAE. Gulls and Terns. 

 'Subfamily Larinae. Gulls. 



EISSA TRIDACTYLA TRIDACTYLA (Linn.). Kittiwake. 

 Accidental. 



The only record for this gull is that of Mr. J. A. Bryant, who 

 took a specimen in the spring of 1897 ( Widmann, p. 24) . It has 

 been impossible to verify this record, as the specimen does not 

 seem to have been preserved. 



LARUS ARGENTATUS Pontoppidan. Herring Gull. 

 Fairly common migrant. 



The Herring Gull sometimes arrives in February, even when 

 the river is filled with floating ice, as in 1916, but more often 

 from the last week in March to the first week in April. This 

 gull probably follows the Mississippi River south in the fall mi- 

 gration, as there are no records of its occurrence here at that 

 season. 



LARUS DEDAWARENSIS Ord. Ring-billed Gull. 

 Not uncommon migrant. 



Though there are but five authentic records of the occurrence
