Preface A shared passion for birds connects people who are almost as diverse as the birds they pursue. This almost inexplicable passion recognizes no boundaries in terms of age, gender, race, religion, and profession. On any given day, a plumber and a playwright, a neurosurgeon and a grandmotherly housewife, a senator and an ornithologist may prowl the same ground in pursuit of the personally unique satisfactions derived from finding birds. Quite expectably, not all people share identical motivations for finding birds; but perhaps more surprisingly, the same people who will split the finest filoplume on issues of species or subspecies identification largely ignore or summarily dismiss questions about what distinguishes birders from birdwatchers from ornithologists. But because very different personal perspectives motivate people's bird interests, very real needs for open communication and shared knowledge exist. This document combines under one cover three different but inextricably entwined aspects of the human interest in birds. Each is covered as a separate part of the book. Parts 1 and 2 detail the academic interest in birds. Because birds cross human-made political and natural geographic boundaries, they become particularly useful for evaluating the interactions between people and the natural world. Basic research of the natural and life histories of birds improves our abiiity to establish the policies that govern our use of natural resources. Parts 3 and 4 address recreational interests in birds, generally known as birding. They present an annotated checklist of the species known to have occurred on Cimarron National Grassland (NG) in historic times and site guides for finding birds on Cimarron NC. Part 5 presents the basic management issues involving the consequences of people's interest in birds. Recreational birders not only spend money tha t contributes to local and regional economies, but they also exert impacts on public facilities tha t must be maintained. Impacts demand administrative attention and managerial resources. By approaching the birds of the Cimarron NG from these three angles, the authors, editors, researchers, and managers who contributed to this document's publica tion hope that academia, recrea tionists, and managers will discover aspects to birds that they overlooked before. By considering the needs of the other groups, each group may realize opportunities for contributing their individual knowledge to enrich our collective understanding of birds and to improve our management of the resources that affect our birds and ourselves. iv
