Krefting and Lee visited Menag¬ 
erie Island and Long Island on August 
7, 1963. Herring Gulls were numerous 
and at each island one young not yet 
able to fly swam out into the lake 
as the boat drew near shore (34). 
65. Ring-billed Gull ( Larus dela - 
warensis (Ord)) 
This gull is an uncommon migrant 
on Isle Royale, and none was recorded 
on the early bird expeditions to the 
island. Shelton found an immature bird 
dead on the shore of Moskey Basin on 
September 1,1962. This specimen is now 
in the Purdue University collections 
(39). Other records are by Wood, Gil¬ 
bert, and Lee and Krefting (21,30,36). 
66. Bonaparte's Gull ( Larus 
Philadelphia (Ord)) 
This gull is an uncommon migrant 
on Isle Royale. It has been seen at 
Grace Harbor, Moskey Basin, and Baker 
Point. Records are by Wood in Birds 
of Michigan and by Shelton in 1960-62 
(all in August or September)(21,39). 
67. Common Tern ( Sterna hirundo 
Linnaeus) 
This tern is a rare migrant. Gil¬ 
bert in 1946 (30) reported that it was 
seen on rare occasions along the 
shores of Isle Royale but never on the 
island proper. Park Service Ranger 
George Pine observed one at the Siski- 
wit camp dock on July 14, 1963 (39). 
68. Caspian Tern ( Hydroprogne 
caspia (Pallas)) 
This tern has been reported from 
Isle Royale only once (21).

69. Mourning Dove ( Zenaidura 
macroura (Linnaeus))

three occasions: Wood (1930) , Wood 
(1951), and by Shelton in 1961 (39). 
70. Rock Dove ( Columba livia 
Gmelin)
