in our list. It has, however, been taken in Colorado twice, and it is 
very likely to eventually be taken here also. 
74. *Sterna antillarum (Lesson)—Lrast Trrn. 
A common migrant, and not a rare breeder, especially in north- 
eastern Nebraska. Aughey found young birds along the Missouri in 
Dixon county in July, 1866, and also records it from Cedar county in 
August and from Lancaster and Sarpy counties in June. L. Skow 
found it breeding at Cut-off lake near Omaha, in the summer of 1893. 
Wilson Tout found five nests on a basin near York during the summers 
of1896 and 1897,and Swenk found it common and breeding inJuly,1903 
on the sandbars of the Niobrara from Badger to its mouth. Numer- 
ous migration records from West Point, Omaha, Peru, and Lincoln. 
77. *Hydrochelidon nigra surinamensis (Gmelin)—Biack Tern. 
j An abundant migrant and rather common breeder in suitable local- 
ities over the state; in the lakes of Cherry county it breeds in great 
numbers. Arrives late in April and departs by the middle of October. 
EXTRALIMITAL: Three species of gulls included in the above key, 
viz.: 40. Rissa tridactyla (Linnaeus)—Kittiwake, 42. Larus glaucus 
Brunnich—Glaucous Gull, and 43. Larus leucopterus Faber—Iceland 
Gull; are northern species which are not known from Nebraska, but 
which winter regularly south to the Great Lakes and even farther, so 
may straggle to our state; especially is this true of the Kittiwake which 
has straggled even toWyoming and Colorado. The California Gull, 53. 
Larus californicus Lawrence, has never been taken in Nebraska so 
far as known, but has been taken a few times in Colorado and once 
even in western Kansas, so may be reasonably expected as a straggler 

here also.

[The first two families included above are represented each by a single 
species in North America. To the first belongs 118. Anhinga anhinga 
(Linnaeus), the Anhinga or Snake Bird of the southern swamps, which oc- 
curs up the Mississippi valley to Kansas and southern Illinois, and which 
was included in Bruner’s list as a Nebraska bird on the authority of a speci-
