The highly variable North American red crossbill complex has presented one of the most controversial problems in avian systematics. Although crossbills wander nomadically and breed all year, they have not become homogenized in bill and body size. This study suggests that this crossbill complex contains several distinctive sibling species that breed sympatrically and show ecological differences.

The Canary: Natural History, Science and Cultural Significance covers the ecology, evolution and conservation of the canary and related species, along with the history and cultural significance of the domestic canary worldwide and various scientific disciplines in which canaries have played a key role as a model species. The book synthesizes the multiple ways in which the canary and its relatives have been, and continue to be, an important scientific model in diverse areas and have influenced human culture. Each chapter is written by international experts in areas such as biogeography, animal behavior, evolutionary ecology, conservation, neurobiology, genetics, or ethnology. In covering this eclectic array of topics, while always focusing on the canary and its close relatives, this book uses the immense appeal of the canary as a vehicle to present notions of ecology, evolution, biodiversity conservation, and so on, to a wide audience. Details all aspects of Crithagra and Serinus canaries as well as relatives like crossbills Structured to begin with more accessible topics like natural history, domestication, and conservation Closes with discussions of more specialized topics like evolution, neurobiology, behavior and genomics

In a comprehensive investigation of macrogeographic variation in the Plain Titmouse (Parus inornatus) complex in western North America, the author assessed population-level patterns of differentiation in morphometric, colorimetric, allozymic, mtDNA, and vocal characters. These suites of traits showed broad geographic concordance, distinguishing Pacific slope from interior populations. These two groups of populations are treated as sibling species.

P. Berthold and E. Gwinnd Bird migration is an intriguing aspect of the living world - so much so that it has been investigated for as long, and as thoroughly, as almost any other natural phenomenon. Aristotle, who can count as the founder of scientific ornithology, paid very close attention to the migrations of the birds he ob served, but it was not until the reign of Friedrich II, in the first half of the 13th century, that reliable data began to be obtained. From then on, the data base grew rapidly. Systematic studies of bird migration were introduced when the Vogelwarte Rossitten was founded, as the first ornithological biological observation station in the world (see first chapter "In Memory of Vogelwarte Rossitten"). This area later received enormous impetus when ex perimental research on the subject was begun: the large-scale bird-ringing experiment initiated in Rossitten in 1903 by Johannes Thienemann (who was inspired by the pioneering studies of C. C. M. Mortensen), the experiments on photoperiodicity carried out by William Rowan in the 1920s in Canada and retention and release experiments performed by Thienemann in the 1930s in Rossitten, the first experimental study on the orientation of migratory birds. After the Second World War, migration research, while continuing in the previous areas, also expanded into new directions such as radar ornithology, ecophysiology and hormonal control mechanisms, studies of evolution, ge netics, telemetry and others.

Urban Ornithology is the first quantitative historical analysis of any New York City natural area’s birdlife and spans the century and a half from 1872 to 2016. Only Manhattan’s Central and Brooklyn’s Prospect Parks have preliminary species lists, not revised since 1967, and the last book examining the birdlife of the entire New York City area is now more than fifty years old. This book updates the avifaunas of those two parks, the Bronx, and other New York City boroughs. It treats the 301 bird species known to have occurred within its study area—Van Cortlandt Park and the adjacent Northwest Bronx—plus 70 potential additions. Its 123 breeding species are tracked from 1872 and supplemented by quantitative breeding bird censuses from 1937 to 2015. Gains and losses of breeding species are discussed in light of an expanding New York City inexorably extinguishing unique habitats.

In this study the author describes Hypsibarbus, a new genus of Asian cyprinid fishes with twelve species, three of them new. A complete set of 45 measurements and 17 counts was taken and analyzed for approximately 250 specimens, including all type material, of more than 1000 specimens encountered, representing most of the major fish collections of the world. The author fully redescribes and illustrates all species in the new genus, and includes keys for their identification. To provide a basis for understanding zoogeographic implications of the phylogeny obtained for Hypsibarbus, the geography and history of the Southeast Asia river basins is discussed in detail.

The aim of Advances in the Study of Behavior remains as it has been since the series began: to serve the increasing number of scientists who are engaged in the study of animal behavior by presenting their theoretical ideas and research to their colleagues and to those in neighboring fields. We hope that the series will continue its "contribution to the development of the field", as its intended role was phrased in the Preface to the first volume in 1965. Since that time, traditional areas of animal behavior have achieved new vigor by the links they have formed with related fields and by the closer relationship that now exists between those studying animal and human subjects.

Nebraska sits at the nexus of continental bird migration and serves as a home?either permanently or seasonally?for nearly 450 species. Major migratory routes pass through the state, creating numerous opportunities to observe the great variety of North American bird species. The annual crane migrations in spring are legendary, and other key events include winter concentrations of bald eagles, flocks of up to thirty thousand grebes, mergansers, and gulls at Lake McConaughy in late fall, and incredible concentrations of waterfowl in the Rainwater Basin in early spring.øBirds of Nebraska captures the variety of Nebraska's ornithological possibilities in a style useful to hobbyists and professionals alike. For the first time in Nebraska ornithology, the authors have provided an exhaustive summary of state bird records compiled into concise but readable accounts of all species of birds reported in the state. This work covers taxonomy, early and late migration dates, high counts, nesting areas, and likely viewing locations.
