ORDER LONGIPENNES: Long-winged Swimmers. 
4. Stercorarius longicaudus, Long-tailed Jaeger. This is an instance 
of what painstaking search may reveal. Mr. H. L. Stoddard shot a fine 
male of this species at Dune Park, September 21, 1915. Mr. F. M. 
Woodruff, of the Chicago Academy of Science, mentioned several other 
occurrences of this boreal species to me. 
5. Larus hyperboreas, Glatvcous Gull. One was shot at Millers, 
August 8, 1897, which is in Mr. Woodruff’s collection. 
6. Larus argentatus, Herring Gull. An abundant winter resident, 
and a few, probably unmated individuals may be seen even in summer. 
April 24, 1915, there were many over the lake at Tremont; August 30, 
1916, about ten at Millers. At the latter place, where there is a fisher- 
men’s colony on the beach, it is one of the common sights to see one 
perched on the top of every post in the lake and numerous others flying 
about. 
7. Larus delawarensis, Ring-billed Gull. Almost as abundant as the 
preceding species, some days even predominating in numbers. A female 
was taken as early as August 3, 1915. Often flies up close to the walker 
along the beach, as if to inspect him. 
8. Larus philadelphia, Bonaparte’s Gull. Although this is next to 
the Herring and Ring-billed Gulls the commonest of the migrating gulls 
on Chicago River and off the lake shore at the parks, we do not see it 
nearly so often as the two other gulls at the south end of the lake. 
Probably we have just missed the days of their abundance. May 10, 
1917, I saw about ten fiying about in the harbor of Michigan City. 
9. Sterna caspia, Caspian Tern. This now turns out to be a rather 
regular and not uncommon migrant here. In late August and early 
September as high as twenty have been seen at one time over the lake 
at Mineral Springs. Stoddard took specimens August 30, 1914, and 
September 4, 1915. I saw one at Millers August 30, 1916. 
10. Sterna forsteri, Foster’s Tern. An abundant migrant, at about 
the same time as the preceding species. August 30, 1916, a flock of 
about two hundred were fishing parallel to the water line near Millers, 
two or three rods from shore, where they were continually diving from 
about twenty feet above the water into the schools of minnows in the 
shallow water below, making as much noise as possible, reminding one 
of a lot of small: boys on a rampage. Mest still had the black crown 
of their nuptial dress. 
11. Sterna hirundo, Common Tern. May almost be called a summer 
resident, as it is common after the first of August, and I have seen 
twenty as late as May 20 (1915), at Mineral Springs. Some days this 
species makes up the bulk of the tern flocks over the lake, on others 
the preceding leads in numbers.
