Download or read book The Ruby-throated Hummingbird written by June Osborne and published by University of Texas Press. This book was released on 2010-07-22 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this invitingly-written book, June Osborne paints a fully detailed portrait of perhaps the best-known hummingbird in the United States, the ruby-throat. There is no mistaking a hummingbird. Even people who hardly know a robin from a sparrow recognize that flash of iridescent feathers and the distinctive hovering flight. So popular have “hummers” become that even casual birdwatchers now travel great distances to hummingbird hot spots to see masses of birds in their annual migrations. Drawing from her own birdwatching experiences, June Osborne offers an “up close and personal” look at a female ruby-throat building her nest and rearing young, as well as an account of a day in the life of a male ruby-throat and stories of the hummers’ migrations between their summer breeding grounds in the United States and Canada and their winter homes in Mexico and Central America. In addition to this life history, Osborne recounts early hummingbird sightings and tells how the bird received its common and scientific names. After an overview of hummingbirds’ distinctive ways of feeding, flying, and conserving energy, she offers a detailed description of the ruby-throat that will help you tell females from males, immature birds from adults, and ruby-throats from similar species. Osborne also takes you on a visit to the “Hummer/Bird Celebration!” at Rockport, reviews hummingbird banding programs, and explains how to attract hummingbirds to your yard or apartment balcony.

Download or read book Advances in Soil Science written by and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil is formed from physical and chemical weathering of rocks - processes described historically because they involve eons of time-by glaciation and by wind and water transport of soil materials, later deposited in deltas and loessial planes. Soil undergoes further transformations over time and provides a habitat for biological life and a base for the development of civilizations. Soil is dynamic -always changing as a result of the forces of nature and particularly by human influences. The soil has been studied as long as history has been documented. Numerous references to soil are found in historical writings such as Aristotle (384-322 B. c. ), Theophrastus (372-286 B. c. ), Cato the Elder (234-149 B. C. ) and Varro (116-27 B. c. ). Some of the earliest historical references have to do with erosional forces of wind and water. The study of soils today has taken on increased importance because a rapidly expanding population is placing demands on the soil never before experienced. This has led to an increase in land degradation and desertification. Desertifica tion is largely synonymous with land degradation but in an arid land context. Deterioration of soil resources is largely human induced. Poverty, ignorance, and greed are the indirect causes of desertification. The direct cause is mismanage ment of the land by practices such as overgrazing, tree removal, improper tillage, poorly designed and managed water distribution systems, and overexploitation.
