The Large Gulls of North America Narrated by Jon L. Dunn Here is a tool to help you become an expert on the large gulls of North America. Gulls are challenging birds to identify. There are lots of species, with subtle differences between them. Furthermore, each gull goes through several transformations in appearance as it matures. If you consider that summer plumage is different from winter plumage, and that first-year, second-year, third-year, and sometimes fourth-year plumages are all different, you end up with 6 to 8 different patterns for each gull (plus one more, the juvenile plumage it wears only in its first season after hatching). No wonder many people are overwhelmed by gulls. But expert birders take particular delight in studying them, and you can also, when you use this DVD to get them all straight. In this DVD, three of the world's top gull watchers share their knowledge and experience: Jon L. Dunn, Larry Rosche, and John Vanderpoel. A close look at gulls Outstanding bird footage distinguishes this DVD, with sharp, detailed closeups of the gulls. You see the birds in flight and perched. Watch them in slow motion. Study side-by-side comparisons of similar species. Here you get a chance to compare the fine points of wing pattern, tail pattern, head shape, and so on. There is new information in this DVD that is not found in any of the field guides. About Jon L. Dunn: Jon Dunn is widely known for his expertise in bird identification.
