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 filled 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 ean 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 Laripan. ‘ Gulls and Terns. 
Subfamily Larinae. Gulls. 
Rissa 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 DELAWARENSIS Ord. Ring-billed Gull. 
Not uncommon migrant. 
Though there are but five authentic records of the occurrence
