Gulls are birding's ultimate identification challenge and Ontario offers some of the best gull watching in North America. There are 22 gull species on the Ontario checklist, which is about 44% of the world's species. The late Peter Grant, author of the first gull identification guide, said the Niagara River was his favourite place for gulls. Niagara holds the world's record of 14 gull species seen on 25 November 1995. OFO field trips often get 10 gull species when thousands of gulls feed along the river in November and December. Seeing Glaucous, Iceland and Thayer's Gulls from the Canadian Arctic with a possibility of finding extreme rarities such as a Ross's Gull or a vagrant Slaty-backed Gull from Siberia is exciting.
