THE JiII!])S OF WISCONSIN. 
Xema sabinii (&abj. SABINE'S GUL.L.. 
A young male was shot on Delavan Lake, Walworth 
County, October 7, 1900, by Mr. H. P. Hare, and is now 
preserved in the collection of N. Hollister. This is probably 
the only authenticated Wisconsin specimen extant. Dr. Hoy 
reported it as having been seen by him at Racine in November, 
1853. Mr. E. W. Nelson is also positive of having shot a speci- 
men on the shore of Lake Michigan, near Chicago, the first of 
April, 1873, but the bird was blown out into the lake and lost. 
In April, 1897, we examined and identified two fresh wings of 
this species, brought to a taxidermist in Janesville to be 
prepared for a hat. This bird was killed on Rock River, near 
that city. 
Sterna caspia Pall. CASPIAN TERN. 
Not common, except, perhaps, on northern Lake Michigan 
and Green Bay. Breeds, or did in 1879-80-81-84, and 1893, on 
different islands in Green Bay and on the north shore. Fre- 
quently found on Lake Michigan in winter. Visits irregularly 
the larger inland lakes. A larg-e flock appeared on Lake 
Koshkonong, May 29, 1896, from which fine specimens were 
shot by L. K. Also noted on Lake Koshkonong a number of 
times during the summer. Not noted by Hoy in his list of 
L852, and consequently not found in King's list of 1879, the 
latter being chiefly a compilation from Hoy. 
Sterna forsteri Nutt. FORSTER'S TERN. 
A common migrant during the first two or three weeks of 
May, and again from September until the middle of October; 
and still later on Lake Michigan. Such birds as breed in the 
state often scatter after the nesting season, and both old and 
young are often found in August. Not nearly as numerous as 
formerly. Although the larger part are migratory a good 
many still nest within the state, principally in the small reedy 
lakes, even in the southern counties. In June, 1872, a large 
number, not less than two hundred pairs, nested at Lake 
Koshkonong. The nests were mostly roughly heaped up 
masses of the dead stems of the cane (Ph rag mites phragmites), 
placed close together, often a dozen or more in a cluster, and 
situated in the more open spaces among the years growth of 
the cane. Plenty as were the nests and eggs, still we had the 
greatest difficulty in getting even two or three positively 
identified sets, as the discovery was soon made that all were not
