The increased attention devoted to the status and possible declines of populations of smaller species of terrestrial birds, known collectively as "landbirds," has resulted in an immediate need for specific methodology for monitoring their populations. This handbook is derived from several sources and is based on the authors' collective experiences in operating monitoring stations. Presented here are a compilation of methods that can be used to assay population size, demographics, and status of virtually all species of landbirds in a wide variety of habitats, from grassland and tundra to...

Prairie and grassland habitats in central and western North America have declined substantially since settlement by Europeans (Knopf 1994) and many of the birds and other organisms that inhabit North American grasslands have experienced steep declines (Peterjohn and Sauer 1999; Johnson and Igl 1997; Sauer, Hines, and Fallon 2007). The species addressed here, Sprague's Pipit (Anthus spragueii), Grasshopper (Ammodramus savannarum) and Baird's (A. bairdii) sparrows, and Chestnut-collared Longspurs (Calcarius ornatus), are grassland birds that are of special conservation concern throughout their...
