Subfamily STERNINAE. Terns. 
STERNA CASPIA Pallas. 
HyYDROPROGNE CASPIA IMPERATOR (Coues). Proposed April, 1917. 
Caspian Tern. 
Occasional visitant. 
_ Two specimens of this tern were taken by Chas. Tindall on 
the Missouri River near Courtney on October 14, 1914. Sev- 
eral more were secured, probably from the same flock, at the 
same place ten days later. 
A specimen was taken at Lake City by Mr. J. A. Bryant in 
the spring of 1886. No other records are available. 
STERNA FoRSTERI Nuttall. Forster’s Tern. 
Not uncommon migrant. 
Small flocks of Forster’s Terns appear late in April and 
early May, and again in September and October. Recent data 
seem to point to the increase of this tern which, though for-

These graceful birds may be looked for on the Swope Park 
lakes or any other large pond, as well as on the Missouri 
River. 
STERNA HIRUNDO Linn. Common Tern. 
Somewhat rare migrant. 
The Common Tern is usually seen late in May or early June 
and again in October. It was formerly rather common. Some 
recent dates are May 10, 1916, when a flock of twelve were 
seen in Swope Park, and June 11, 1916, when fifteen were ob- 
served feeding in their characteristic manner about the mouth 
of Big Blue River. 
STERNA ANTILLARUM (Lesson). 
STERNULA ANTILLARUM ANTILLARUM Lessor. Proposed April. 
1917. Least Tern. 
Somewhat rare migrant and occasional summer resident. 
Least Terns make their appearance in small numbers during 
the last few days in April in some years, but oftener in the first 
week of May. They leave for the South during the first fifteen 
days of September. 
Prior to 1900 this dainty bird was commonly met with on the 
Missouri River and about neighboring ponds and marshes. It
