Zonotrichia lemophrys (Forst.)--White-crowned Sparrow. What Mr. Eidgway now considers to be this species was found by him breeding very abundantly at Summit Meadows, the highest point of Donner Lake Pass, in the Sierra Nevada, in July, 18G7. Zonotrichia gambeli intermedi Eidgw.--Intermediate White-crowned Spaixow. What Mr. Eidgway thought to be this species was found by him breeding very abundantly at the Summit Meadows; but Mr. Eidgway now considers it more probable that the bird observed there was Z. leucophrys. Numerous specimens were also obtained by him in the West Humboldt Mountains. This species was met with several times in tbe more southern portions of the State, particularly in the elevated and fertile valleys just north of Mount Magiuder; again, sparingly, east of Spring Mountain, in September. Zonotrichia coronata (Pall.) Baird.--Golden-crowned Sparrow. The only specimen seen of this species was captured by Mr. Eidgway, who states that it was shot from a flock of Z. intermedia. "Its occurrence on the West Humboldt Mountains may be accounted for by the fact that many of the Pacific coast species have a tendency to straggle eastward during their migrations, among those which reach this range, besides the bird under consideration, being Melospiza guttata, Pipilo oregonns, Lanivireo eassini, Helminthophaga lutescens, &c." Spizella montana (Forst.) Eidgw.--Tree Sparrow. A common species throughout the northern regions, though farther south was found more sparingly and only in the more elevated and fertile areas. This species is very widely distributed, specimens having been procured on the Yukon Eiver, where it also breeds. Captain Bendire mentions it as occurring about Tucson during winter; have found it in Dakota during the...

This book was released on 2010-08-25 with total page 187 pages. Available in PDF, EPUB and Kindle. Book excerpt: At the biological crossroads of the Americas, Costa Rica hosts an astonishing array of plants and animals—over half a million species! Ecotourists, birders, and biologists come from around the world, drawn by the likelihood of seeing more than three or four hundred species of birds and other animals during even a short stay. To help all these visitors, as well as local residents, identify and enjoy the wildlife of Costa Rica, Carrol Henderson published Field Guide to the Wildlife of Costa Rica in 2002, and it instantly became the indispensable guide. Now Henderson has created a dedicated field guide to more than one hundred tropical butterflies, moths, and other invertebrates that travelers are most likely to see while exploring the wild lands of Costa Rica. He includes fascinating information on their natural history, ecology, identification, and behavior gleaned from his forty years of travels and wildlife viewing, as well as details on where to see these remarkable and beautiful creatures. The butterflies, moths, and other invertebrates are illustrated by over 180 stunning and colorful photographs—most of which were taken in the wild by Henderson. A detailed and invaluable appendix that identifies many of Costa Rica's best wildlife-watching destinations, lodges, and contact information for trip-planning purposes completes the volume.

Download or read book The Avian Migrant written by John H. Rappole and published by Columbia University Press. This book was released on 2013-06-11 with total page 459 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of migration, regardless of the distance involved, is to exploit two or more environments suitable for survival or reproduction over time, usually on a seasonal basis. Yet individual organisms can practice the phenomenon differently, and birds deploy unique patterns of movement over particular segments of time. Incorporating the latest research on bird migration, this concise, critical assessment offers contemporary readers a firm grasp of what defines an avian migrant, how the organism came to be, what is known about its behavior, and how we can resolve its enduring mysteries. John H. Rappole's sophisticated survey of field data clarifies key ecological, biological, physiological, navigational, and evolutionary concerns. He begins with the very first migrants, who traded a home environment of greater stability for one of greater seasonality, and uses the structure of the annual cycle to examine the difference between migratory birds and their resident counterparts. He ultimately connects these differences to evolutionary milestones that have shaped a migrant lifestyle through natural selection. Rather than catalogue and describe various aspects of bird migration, Rappole considers how the avian migrant fits within a larger ecological frame, enabling a richer understanding of the phenomenon and its critical role in sustaining a hospitable and productive environment. Rappole concludes with a focus on population biology and conservation across time periods, considering the link between bird migration and the spread of disease among birds and humans, and the effects of global warming on migrant breeding ranges, reaction norms, and macroecology.

Download or read book The Evolutionary Synthesis written by Ernst Mayr and published by Harvard University Press. This book was released on 1998 with total page 524 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biology was forged into a single, coherent science only within living memory. In this volume the thinkers responsible for the "modern synthesis" of evolutionary biology and genetics come together to analyze that remarkable event. In a new Preface, Ernst Mayr calls attention to the fact that scientists in different biological disciplines varied considerably in their degree of acceptance of Darwin's theories. Mayr shows us that these differences were played out in four separate periods: 1859 to 1899, 1900 to 1915, 1916 to 1936, and 1937 to 1947. He thus enables us to understand fully why the synthesis was necessary and why Darwin's original theory--that evolutionary change is due to the combination of variation and selection--is as solid at the end of the twentieth century as it was in 1859.
Download or read book Biophysical Ecology written by D. M. Gates and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 631 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this book is to make analytical methods available to students of ecology. The text deals with concepts of energy exchange, gas exchange, and chemical kinetics involving the interactions of plants and animals with their environments. The first four chapters are designed to show the applications of biophysical ecology in a preliminary, sim plified manner. Chapters 5-10, treating the topics of radiation, convec tion, conduction, and evaporation, are concerned with the physical environment. The spectral properties of radiation and matter are thoroughly described, as well as the geometrical, instantaneous, daily, and annual amounts of both shortwave and longwave radiation. Later chapters give the more elaborate analytical methods necessary for the study of photosynthesis in plants and energy budgets in animals. The final chapter describes the temperature responses of plants and animals. The discipline of biophysical ecology is rapidly growing, and some important topics and references are not included due to limitations of space, cost, and time. The methodology of some aspects of ecology is illustrated by the subject matter of this book. It is hoped that future students of the subject will carry it far beyond its present status. Ideas for advancing the subject matter of biophysical ecology exceed individual capacities for effort, and even today, many investigators in ecology are studying subjects for which they are inadequately prepared. The potential of modern science, in the minds and hands of skilled investigators, to of the interactions of organisms with their advance our understanding environment is enormous.
