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.

A flock of Pinyon Jays arrive in a flash of blue, and leave again just as suddenly. This once mysterious bird is now the subject of over 20 years of intensive research involving over one thousand colour-marked jays by Russell Balda, John Marzluff and their colleagues and helpers. This plain blue bird has turned out to be anything but plain in its biology and behaviour. Uniquely dependent on the seeds of the Pinyon Pine for food, they have developed a number of behavioural and morphological adaptations to best utilise this resource, above all caching enough seeds each autumn to supply their needs throughout the winter and fuel their unusual habit of nesting in late winter. Fluctuations in pine-seed supply, both by season and between years, poses special problems for these birds and has led to their extremely flexible and complex social system in which learning and memory play an unusually large part. They store pine seeds and retrieve them with uncanny accuracy; they form lifelong pair bonds and nest colonially, occasionally involving younger birds to help established pairs rear the young; and they use their large vocabulary to coordinate activities within one of the largest known avian societies. This intriguing story will fascinate both the enthusiastic amateur birder and the professional alike. Packed with information, it presents Pinyon Jay biology in a readable form and places them into the wider context of studies on bird ecology and evolution. Fine illustrations by Tony Angell, with additional pictures by Caroline Bauder, complete this attractive addition to any birder's bookshelf.
