Synopsis Water Birds and Their Wetland Resources in Relation to Oil Development at Storkersen Point, Alaska by : Robert D. Bergman

Results of a 5-year study of the bird populations at Storkersen Point on the Alaska Coastal plain. Based on the characteristics of the birds and their wetland resources, recommendations for the preservation of tundra wetlands are made and to minimize negative effects of petroleum development on water birds.

Synopsis Use of Wetland Habitats by Birds in the National Petroleum Reserve--Alaska by : Dirk V. Derksen

Distribution, abundance, and use of wetland habitats by migratory birds were studied at 2 interior and 3 outer Arctic Coastal Plain sites in the National Petroleum Reserve in Alaska in 1977 and 1978.

Synopsis Wetland Use by Waterbirds that Winter in Coastal Texas by : James Thomas Anderson

"Wetland use and selection by species of waterbirds (shorebirds, wading birds, gulls, terns, grebes, cormorants, and pelicans) between the Rio Grande and Galveston Bay in coastal Texas were studied during September and November of 1991-92 and during January and March of 1992-93. Based on a stratified (by dominant land use) random sample of 64.75-ha plots, 88 species of waterbirds using wetlands were observed. Ranks of density and proportion of feeding bird indicated that cormorants and pelicans preferred wetlands with less than 30% vegetation. Gulls, terns, and skimmers preferred certain types of estuarine and lacustrine wetlands with less than 30% vegetation, especially estuarine subtidal rock bottom rubble types. Grebes and rails selectively used palustrine aquatic-bed rooted vascular and unconsolidated bottom mud wetland types. Herons, egrets, and bitterns preferred certain types of lacustrine and estuarine wetlands. Shorebirds used estuarine intertidal wetlands. Waterbird management should focus on 26 of the 82 wetland types that we prioritized in the coastal plains of Texas. Management should focus on protecting, enhancing, or restoring complexes of various wetland types, especially estuarine aquatic-bed and intertidal unconsolidated substrate types"--Page 1

Synopsis Birds of Massachusetts and Other New England States, Vol. 1 by : Edward Howe Forbush

Excerpt from Birds of Massachusetts and Other New England States, Vol. 1: Water Birds, Marsh Birds and Shore Birds Many papers on the birds of Massachusetts have been published within the last fifty years, notably the Birds of Massachusetts, by Messrs. Reginald Heber Howe J r., and Glover M. Allen, but most of them are mere local lists with annotations, and not one of them contains adequate descriptions or colored plates of the species. The de mand for such information as plates and descriptions alone can furnish has grown in sistent with the years. Not only do people of rural communities seek such knowledge; the great and increasing army of bird students also requires it. Birds may be ranked among the noblest forms of life. Experience has shown that without special protection at the hands of man many species are likely to become extinct. Some of those that are hunted as game now need special care. Licenses to hunt certain birds within the borders of the Commonwealth are issued to citizens annually, and the number of such hunters now approximates one hundred thousand. Probably most of these hunters would be unable to recognize all the birds that they are privileged to shoot under their licenses, to say nothing of the large number of species that are protected by law. Many people who hunt birds desire such information concerning them as it is purposed to include in the present volume. The book is intended, therefore, to fill a long-felt want. The objects of the work are: (1) to interest the general public of Massachusetts and New England in birds and their rational conservation, (2) to provide our citizens with a means of identifying birds in the field or in the hand, (3) to furnish such other information regarding birds as the people desire and need. Long experience as State Ornithologist in answering their questions has perhaps qualified the author in some degree for the latter service.
