Book Description
The average person can name more bird species than they think, but do we really know what a bird “species” is? This open access book takes up several fascinating aspects of bird life to elucidate this basic concept in biology. From genetic and physiological basics to the phenomena of bird song and bird migration, it analyzes various interactions of birds – with their environment and other birds. Lastly, it shows imminent threats to birds in the Anthropocene, the era of global human impact. Although it seemed to be easy to define bird species, the advent of modern methods has challenged species definition and led to a multidisciplinary approach to classifying birds. One outstanding new toolbox comes with the more and more reasonably priced acquisition of whole-genome sequences that allow causative analyses of how bird species diversify. Speciation has reached a final stage when daughter species are reproductively isolated, but this stage is not easily detectable from the phenotype we observe. Culturally transmitted traits such as bird song seem to speed up speciation processes, while another behavioral trait, migration, helps birds to find food resources, and also coincides with higher chances of reaching new, inhabitable areas. In general, distribution is a major key to understanding speciation in birds. Examples of ecological speciation can be found in birds, and the constant interaction of birds with their biotic environment also contributes to evolutionary changes. In the Anthropocene, birds are confronted with rapid changes that are highly threatening for some species. Climate change forces birds to move their ranges, but may also disrupt well-established interactions between climate, vegetation, and food sources. This book brings together various disciplines involved in observing bird species come into existence, modify, and vanish. It is a rich resource for bird enthusiasts who want to understand various processes at the cutting edge of current research in more detail. At the same time it offers students the opportunity to see primarily unconnected, but booming big-data approaches such as genomics and biogeography meet in a topic of broad interest. Lastly, the book enables conservationists to better understand the uncertainties surrounding “species” as entities of protection.

Book Description
A comprehensive and beautifully illustrated overview to the birds of Maine The first comprehensive overview of Maine’s incredibly rich birdlife in more than seven decades, Birds of Maine is a detailed account of all 464 species recorded in the Pine Tree State. It is also a thoroughly researched, accessible portrait of a region undergoing rapid changes, with southern birds pushing north, northern birds expanding south, and once-absent natives like Atlantic Puffins brought back by innovative conservation techniques pioneered in Maine. Written by the late Peter Vickery in cooperation with a team of leading ornithologists, this guide offers a detailed look at the state’s dynamic avifauna—from the Wild Turkey to the Arctic Tern—with information on migration patterns and timing, current status and changes in bird abundance and distribution, and how Maine's geography and shifting climate mold its birdlife. It delves into the conservation status for Maine's birds, as well as the state's unusually textured ornithological history, involving such famous names as John James Audubon and Theodore Roosevelt, and home-grown experts like Cordelia Stanwood and Ralph Palmer. Sidebars explore diverse topics, including the Old Sow whirlpool that draws multitudes of seabirds and the famed Monhegan Island, a mecca for migrant birds. Gorgeously illustrated with watercolors by Lars Jonsson and scores of line drawings by Barry Van Dusen, Birds of Maine is a remarkable guide that birders will rely on for decades to come.

Book Description
A compact, comprehensive, and very silly field guide featuring more than 200 of the rudest birds on earth—from the creator of the Webby Award–winning hit Instagram account! Effin’ Birds is the most eagerly anticipated new volume in the grand and noble profession of nature writing and bird identification. Sitting proudly alongside Sibley, Kaufman, and Peterson, this book contains more than 150 pages crammed full of classic, monochrome plumage art paired with the delightful but dirty aphorisms (think “I’m going to need more booze to deal with this week”) that made the Effin’ Birds feed a household name. Also included in its full, Technicolor glory is John James Audubon’s most beautiful work matched with modern life advice. Including never-before-seen birds, insults, and field notes, this guide is a must-have for any effin’ fan or birder.

Book Description
Songbirds are often used as indicators of environmental health. From the canary in the coalmine, to shifts in demographics and population patterns, birds tell us when things are not well. More often than not, these observable trends are a result of adaptive behavior that has evolved over many generations. Understanding foundation concepts of songbird behavior, including the rate at which behavioral changes occur and the limits of plasticity, is a requirement for anyone interested in sustaining healthy songbird populations in the Anthropocene. Yet, our world is changing rapidly. Can songbirds adapt quickly enough to keep up? Observed declines in many species worldwide suggest that the answer is no. To avoid extinction for many species, our conservation strategies must be broader and more intentional. For example, are there ways to actively manage habitats so that vital cue-response systems are kept intact? Anthropogenic factors are also altering how birds select mates and habitats, sometimes in ways that decrease fitness. Can biologists actively manipulate behavior to mitigate these mismatches? The first goal of this book is to educate academics and managers alike about the foundational behaviors that drive songbird activity and demographic patterns. Topics such as migration, habitat selection, communication, etc., are explored by renown songbird biologist to bring the reader up to speed on the latest advancements in the field. However, each author is also versed in the principles of conservation. The second goal of this book is to explore the current issues that songbirds face in an increasingly anthropic world – and to discuss the role of behavior in the development of management solutions. By broadening our conservation toolkit, we can be more prepared to manage songbird populations and communities within the environmental challenges of the Anthropocene.

Book Description
A funny, colorful, fascinating tour through the work and life of one of today’s most influential graphic designers. Esquire. Ford Motors. Burton Snowboards. The Obama Administration. While all of these brands are vastly different, they share at least one thing in common: a teeny little bit of Aaron James Draplin. Draplin is one of the new school of influential graphic designers who combine the power of design, social media, entrepreneurship, and DIY aesthetic to create a successful business and way of life. Pretty Much Everything is a mid-career survey of work, case studies, inspiration, road stories, lists, maps, how-tos, and advice. It includes examples of his work—posters, record covers, logos—and presents the process behind his design with projects like Field Notes and the “Things We Love” State Posters. Draplin also offers valuable advice and hilarious commentary that illustrates how much more goes into design than just what appears on the page. With Draplin’s humor and pointed observations on the contemporary design scene, Pretty Much Everything is the complete package.

Book Description
In this powerful call to action, conservationist and environmental lawyer Jim Blackburn offers an unconventional yet feasible plan to protect the Texas coast. The coast is in danger of being damaged beyond repair due to the gradual starvation of freshwater inflows to its bays, the fragmentation of large tracts of land, and general public neglect. Most importantly, it is threatened by our denial that the coast faces major threats and that its long-term health provides significant economic benefits. To save coastal resources, a successful plan needs to address the realities of our current world. The challenge is to sustain an economy that creates optimism and entrepreneurship while considering finite natural resources. In other words, a successful plan to save the Texas coast needs to be about making money. Whether visiting with farmers and ranchers or oil and chemical producers, Blackburn recognizes that when talking about the natural environment in monetary terms, people listen. Many of the services we get from the coast are beginning to be studied for their dollar values, a trend that might offer Texas farms and ranches the potential for cash flow, which may in turn alter conservation practices throughout Texas and the United States. Money alone cannot be the only motivation for caring about the Texas coast, though. Blackburn encourages Texans to get to know this landscape better. Beautifully illustrated and accessibly written, A Texan Plan for the Texas Coast weaves together a challenging but promising plan to protect the coast through economic motivation, thoughtful litigation, informed appreciation, and simple affection for the beauty and life found on the Texas coast.

Book Description
Urbanization is next to global warming the largest threat to biodiversity. Indeed, it is becoming increasingly evident that many bird species get locally extinct as a result of urban development. However, many bird species benefit from urbanization, especially through the abundance of human-provided resources, and increase in abundance and densities. These birds are intriguing to study in relation to its resilience and adaption to urban environments, but also in relation to its susceptibility and the potential costs of urban life. This Research Topic consisting of 30 articles (one review, two meta-analyzes and 27 original data papers) provides insights into species and population responses to urbanization through diverse lenses, including biogeography, community ecology, behaviour, life history evolution, and physiology.

Book Description
Feathers are amazing structures unique to birds and, for a variety of reasons, they need to be renewed periodically as a whole in a process called moult. During this process, all of the functions of plumage are impaired and most aspects of a bird's life are affected. Every moult determines a bird's appearance anew, and restores plumage efficacy for flight and insulation. Moult profoundly affects physiology and the organization of the annual cycle, and it constrains reproduction and migration. Given these major impacts, which are equal to the other annual challenges of reproduction and migration, it is surprising that research on moult has largely been so neglected a subject. Lukas Jenni and Raffael Winkler have brought together the widely scattered results of studies on the processes and consequences of moult in birds. This book opens with an overview of the functions of plumage, and of feather maintenance and feather wear, and then introduces the two functions of moult: replacement of worn feathers and adjustment of plumage characteristics and appearance. The body of the book then examines feather-growth and the physiology, energetics and control of moult, and how various other physiological processes interact with moult and may compensate for its costs. Significantly, the authors explain how variations in moult and feather quality affect a bird's overall plumage quality, and they highlight the resulting consequences in terms of physical performance, appearance and signalling. Finally, there is a review of all the various solutions that birds have developed to fit moult into the annual cycle. This long-awaited book covers for the first time all aspects of the biology of moult and fills an important gap in the literature, completing our understanding of how the most important annual events in a bird's life fit together into a coherent whole. It draws on a wide range of information – from penguins to small passerines, from raptors to wildfowl – to highlight the variety of the subject and to pinpoint the many gaps in our knowledge along with avenues for fruitful further research.
