The Feathers Of Winter, Paul A. Johnsgard
Paul Johnsgard Collection
For many Nebraska birders, the last big event of the year is the Audubon Christmas Bird Count, which is held annually during the last week of December. It is an occasion to join with friends in a day out to try see as many species as possible in a single day. More importantly, it provides a database that, combined with those of more than 50,000 other observers, provides a highly documented population sample of early-winter birds throughout North America, Latin America and the Caribbean region. The tradition began in 1900, and as of 2011 there have been 111 national counts. …

Nebraska is a regular host to 17 species of hawks, as well as two eagles and eight owls. Collectively, all these impressive-looking birds are known as “raptors,” which refers to their strong, sharply decurved and pointed beaks, their sharp, curved talons and their associated predatory abilities. Hawk and eagles are often called “diurnal raptors,” since they all hunt during daylight hours, whereas most of Nebraska’s owls hunt at night and are described as nocturnal raptors. But few biological statements lack exceptions, and some owls such as the burrowing owl are daytime-hunters, and some such as the great homed owl hunt …

Much less apparent and well known than the annual crane migration is Nebraska’s role in the spring and fall migrations of shorebirds such as sandpipers, plovers, curlews and godwits. These migrations are inconspicuous, in part because of the fact that most long-distance shorebird flights occur at night. Shorebirds also never migrate in the enormous flocks that are so typical of geese and cranes, and their flights are usually unaccompanied by loud calls. Yet, they are massive if nearly invisible migrations, involving over 30 species and an estimated 200,000–300,000 birds. Many of the species travel from South American wintering grounds, and …
