Download or read book Field Guide to North American Flycatchers written by Cin-Ty Lee and published by Princeton University Press. This book was released on 2023-04-04 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: A richly illustrated, portable field guide to flycatcher identification The identification of Empidonax flycatchers and pewees can be a daunting challenge for even the most seasoned birder. Field Guide to North American Flycatchers takes bird identification to an entirely new level by training readers to observe subtle differences in structure, color patterns, and vocalizations before delving into the finer details of a particular species. Because the plumages of flycatchers are so similar, this one-of-a-kind guide uses illustrations that highlight slight variances among species that photos often miss. One of the last frontiers of bird identification is now accessible to everyone—once one knows what to look for. Uses a holistic approach that makes flycatcher identification possible even for beginners Features a wealth of beautiful illustrations that depict every species in North America Shows how to observe subtle differences in structure, plumage contrasts, and vocalizations, which together create a distinctive overall impression of the bird Includes detailed audio spectrograms and seasonal distribution maps for each species Shares invaluable tips for successful identification in all kinds of field settings Its compact size and field-friendly layout make it the ideal travel companion for any birder

Download or read book The North American Quails Partridges and Pheasants written by Paul Johnsgard and published by Lulu.com. This book was released on 2017-10-10 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book documents the biology of six species of New World quails that are native to North America north of Mexico (mountain, scaled, Gambel's, California, and Montezuma quails, and the northern bobwhite), three introduced Old World partridges (chukar, Himalayan snowcock, and gray partridge), and the introduced common (ring-necked) pheasant. Collectively, quails, partridges, and pheasants range throughout all of the continental United States and the Canadian provinces. Two of the species, the northern bobwhite and ring-necked pheasant, are the most economically important of all North American upland game birds. All of the species are hunted extensively for sport and are highly popular with naturalists, birders, and other outdoor enthusiasts.

Download or read book The North American Grouse Their Biology and Behavior written by Paul Johnsgard and published by Lulu.com. This book was released on 2016 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ten currently recognized species of grouse in North America have played an important role in America's history, from the famous but ill-fated heath hen, a primary source of meat for the earliest New England immigrants, to the ruffed grouse, currently one of the most abundant and soughtafter upland game birds in more than 40 states and provinces. This book summarizes the ecology, reproductive biology, and social behavior of all ten of the extant North American grouse species. It also describes the current status of grouse populations, some of which are perilously close to extinction. The social behavior of grouse is of special biological interest because among these ten species there is a complete mating system spectrum, from seasonally monogamous pair-bonding to highly promiscuous mating patterns. The latter group illustrates the strong structural and behavioral effects of sexual selection resulting from nonmonogamous mating. These influences reach a peak in the development by some grouse species of engaging in mating "leks," arena-like competitions performed by males while attempting to attract fertile females, and also provide opportunities for females to select optimum mating partners. These sexual competitions also promote strong differences evolving in sexual signaling behaviors ("displays") among closely related species. Nevertheless, a relatively high incidence of mating errors and resulting hybridization often occurs in spite of these marked behavioral differences. In addition to a text of 101,000 words, the book includes 16 range maps, 37 line drawings, and 38 photographs by the author, as well as nearly 1,400 literature citations.

Available in PDF, EPUB and Kindle. Book excerpt: Love Canal. Exxon Valdez. Times Beach. Sacramento River Spill. Amoco Cadiz. Seveso. Every area of the world has been affected by improper waste disposal and chemical spills. Common hazardous waste sites include abandoned warehouses, manufacturing facilities, processing plants, and landfills. These sites poison the land and contaminate groundwater and drinking water. A sequel to the bestselling Ecological Risk Assessment, Ecological Risk Assessment for Contaminated Sites focuses on how to perform ecological risk assessments for Superfund sites and locations contaminated by improper disposal of wastes, or chemical spills. It integrates the authors' extensive experience in assessing ecological risks at U.S. government sites with techniques and examples from assessments performed by others. Conducting an ecological risk assessment on a contaminated site provides the information needed to make decisions concerning site remediation. The first rule of good risk assessment is "don't do anything stupid". With the practical preparation you get from Ecological Risk Assessment for Contaminated Sites you won't.
