Body mass, or weight, is the most useful descriptive measure of relative body size in birds. Masses are usually reported in avian studies of comparative ecology, physiology, breeding biology, and zoology. In addition, adult body mass is a vital statistic for studies of allometric relationships, growth and development, flight, and biometrics. The data in this handbook was compiled to provide a ready reference source for body masses of most of the world's species of birds. Masses of over 5,800 species are presented, representing about 65% of the known birds. Information for each species includes, when available, the mean, standard deviation, range, sample size, collecting locale and season, an...

Pete Dunne has taught birding to beginners for years, but he has never found the right book to help them get started. Now the popular birding author identifies the skills and tools available to people with any amount of interest, great or small, in bird watching. Beginning with backyard birding and moving through a quick but comprehensive survey of tools of the trade, Dunne outlines ten basic, simple steps in bird identification that can make a birder out of the most casual of observers. He goes on to show beginning birders how to use their skills to explore new horizons through birding by ear, birding by telescope, and finding and identifying rare or difficult birds. Written in the lively, authoritative style that has made Dunne one of the most popular writers in this field today, Pete Dunne on Bird Watching will inspire in readers both a growing passion for birding and a lifelong respect for the natural world and its inhabitants.
The San Marcos springs have flowed for around ten million years. In this ode to the river they form, Jim Kimmel brings us a picture of a watercourse brimming with life, past and present. Native, non-native, prehistoric, and modern-day plants, animals, and people have inhabited the river and its banks. Kimmel touches on them all with the affectionate and knowledgeable voice of one whose own life has been closely linked to the San Marcos. As readers journey with Kimmel from the river's headwater springs to its junction with the Guadalupe River, The San Marcos: A River's Story will capture the imagination and provide valuable information about the river and its crucial role in the ecological health of Texas. Original photographs by Jerry Touchstone Kimmel add a sense of the beauty and complexity of the river.
