Observations of Franklin’s Gulls (Larus pipixcan) in Idaho have been limited. This paper summarizes recent published and unpublished records, and shows that this gull has increased in the state. Franklin’s Gull was first recorded in Idaho at Minidoka Dam, Snake River, on 28 July 1910 by Stanley Jewett (Slipp 1942). Through the early 1970s it was recorded from several wetlands in southeastern Idaho, but was known to breed only at Gray’s Lake, Caribou Co., site of a large colony, and at Lake Walcott, Minidoka Co., where about 1000 pairs nested (Burleigh 1972). One bird collected near Lewiston, Nez Perce Co., and two collected near Meridian, Ada Co., furnished the only records outside of southeastern Idaho (Burleigh 1972).
