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) — Least Tern. 



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 

 ofl896 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) — Black Tern. 



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 toW)'oming 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.

Family ANHINGID^I— Anhingas 



[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-
