Ring-billed gull . : CW69-4/63-1998E-PDF
"The aerial acrobatics and tameness of gulls have always given them a special appeal. It is hard to imagine seashores and lakeshores without them - effortlessly riding the wind over the waves, hovering over quays, and trailing after fishing boats, in a daily quest for food. Over the past 50 years, gulls have become increasingly numerous and tame, and they have greatly expanded their range. Now many of us see "seagulls" as we go about our daily lives, whether we live in a city or in the country. Although 18 species of gulls breed in Canada, this dramatic population increase involves only a few gull species. One of these, the Ring-billed Gull, called Larus delawarensis by scientists, has become the best known gull in Canada"--p. [2].
