In this comprehensive, yet easy-to-use book, Kent Rylander distills data from many sources to provide an authoritative guide to the behavior of Texas birds. He begins by explaining the principles of animal behavior and illustrating how they can be applied to interpreting bird behaviors in the field. The majority of the book is devoted to accounts of more than 400 species of birds that are most likely to be encountered by Texas birdwatchers. Each account describes such behaviors as feeding, courtship, parenting, and other behaviors that are significant for that species. References to interesting and important articles from scientific journals are incorporated in the species accounts where appropriate, and line drawings illustrate some of the behaviors described.
Kent Rylander is Professor of Biological Sciences at Texas Tech University in Lubbock.
Designed for intermediate to advanced birders, Birds of the Trans-Pecos provides an annotated checklist of all 482 species found in the region. The species accounts include seasonal distribution, documentation of nesting, most likely habitat, and the bird's status as a "Texas Review Species." The authors also describe the geography and bird habitats of the Trans-Pecos; federal and state parklands in the area (including Big Bend and Guadalupe Mountains), with the species that occur in each; and the mountain-breeding birds and species of special interest.
Basic Texas Birds is organized by bird families to aid in identifying any bird you see in the wild. It is loaded with resources, including:200 full-color, close-up photos of the birds State-of-the-art range maps—the most accurate of any currently available—that show each species' distribution within the state Up-to-date species accounts that provide a wealth of current and historical information, including each bird's appearance, habitat, status, and distribution, and that also identify similar species A glossary of terms used in bird identification A list of selected readings for learning more about birds found in Texas The Texas Ornithological Society's list of birds documented in Texas
Much more convenient for identifying common birds than a comprehensive state or national field guide, Basic Texas Birds is a must-have resource for both beginning and experienced birders.
Migration is shown by many kinds of animals, including butterflies and other insects, mammals, marine turtles and fish, but in none is it as extensively developed as in birds. The collective travel routes of birds span almost the entire globe, with some extreme return journeys covering more than 30,000 km. As a result of migration, bird distributions are continually changing – in regular seasonal patterns, and on local, regional or global scales.
Migration has repeatedly prompted familiar questions, such as where birds go or come from, why do they do it, how do they know when and where to travel, and how do they find their way? In this book, Ian Newton sets out to answer these – and other – questions.
The book is divided into four main sections: the first is introductory, describing the different types of bird movements, methods of study, and the main migration patterns seen around the British Isles; the second part is concerned mainly with the process of migration – with timing, energy needs, weather effects and navigation; the third with evolution and change in migratory behaviour; and the fourth with the geographical and ecological aspects of bird movements.
What would normally be a quiet, very private event was, in Alex's case, headline news. Over the thirty years they had worked together, Alex and Irene had become famous—two pioneers who opened an unprecedented window into the hidden yet vast world of animal minds. Alex's brain was the size of a shelled walnut, and when Irene and Alex first met, birds were not believed to possess any potential for language, consciousness, or anything remotely comparable to human intelligence. Yet, over the years, Alex proved many things. He could add. He could sound out words. He understood concepts like bigger, smaller, more, fewer, and none. He was capable of thought and intention. Together, Alex and Irene uncovered a startling reality: We live in a world populated by thinking, conscious creatures.
The fame that resulted was extraordinary. Yet there was a side to their relationship that never made the papers. They were emotionally connected to one another. They shared a deep bond far beyond science. Alex missed Irene when she was away. He was jealous when she paid attention to other parrots, or even people. He liked to show her who was boss. He loved to dance. He sometimes became bored by the repetition of his tests, and played jokes on her. Sometimes they sniped at each other. Yet nearly every day, they each said, "I love you."
Alex and Irene stayed together through thick and thin—despite sneers from experts, extraordinary financial sacrifices, and a nomadic existence from one university to another. The story of their thirty-year adventure is equally a landmark of scientific achievement and of an unforgettable human-animal bond.
