GULLS OF THE WORLD – A Photographic Guide
Author: Klaus Malling Olsen

“By my own experience, when I photographed birds from many locations in the world. The most difficult part for me was to get the correct ID when it came to gulls.
Because their plumages change patterns according to respective period of age. The odds increase the possibilities of error. Well, this Photographic Guide simplify the process to get the right names of the photographed gulls, from any location in the world.
There are over 600 great quality photos to compare with yours. These photos are accompanied with pertinent information about descriptions, locations, habitats, migration maps, etc. A total of 368 pages!
Reading this well written and structured Guide, immediately encouraged me to revisit my photo archives, verify and correct any wrongly named gulls. For me, I admit that this guide has advanced me to the point when, if I shoot a scene of gulls mixed together in a migration flock, I’ll be able to ID each of the gull species easily. Klaus Malling Olsen has done a great job with “Gulls of the World” I’d love that!

The Magnificent Frigatebird (Fregata magnificens) is a seabird of the frigatebird family Fregatidae. With a length of 89–114 centimetres (35–45 in) it is the largest species of frigatebird. It occurs over tropical and subtropical waters off America, between northern Mexico and Ecuador on the Pacific coast and between Florida and southern Brazil along the Atlantic coast. There are also populations on the Galápagos Islands in the Pacific and the Cape Verde islands in the Atlantic. Also in Northern Peru.
The magnificent frigatebird is a large, lightly built seabird with brownish-black plumage, long narrow wings and a deeply forked tail. The male has a striking red gular sac which it inflates to attract a mate. The female is slightly larger than the male and has a white breast and belly. Frigatebirds feed on fish taken in flight from the ocean’s surface (often flying fish), and sometimes indulge in kleptoparasitism, harassing other birds to force them to regurgitate their food.
