“…Intraspecific brood parasitism commonly occurs within American Avocet colonies (Bent 1962, Vermeer 1971, Kondla 1977, Kondla and Pinel 1978, Giroux 1985, Koonz 1985, Dole 1986, Kuyt and Johns 1992. The normal clutch size for American Avocets is four, but when two or more females lay eggs in the same nest, superclutches of >6 eggs can occur (Gibson 1971, Koonz 1985.…”

“…The frequency of intraspecific brood parasitism is greater on islands and in more northerly portions of the breeding range (Kondla andPinel 1978, Robinson et al 1997). Reported frequencies of intraspecific brood parasitism ranged from 8% of 13 nests to 50% of 30 nests (Vermeer 1971, Kondla and Pinel 1978, Giroux 1985, Koonz 1985. Dole (1986) found that nest success was greater for four-egg clutches than clutches with either less than or greater than four eggs.…”

Breeding habitat can be found in tilled, alkali, ephemeral, temporary, seasonal, semipermanent, and permanent wetlands, and in impoundments, sewage lagoons, and evaporation ponds (Stewart and Kantrud 1965, Stewart 1975, Weber 1978, Faanes 1982, Weber et al 1982, Kantrud and Stewart 1984, Giroux 1985, Colwell 1986, Dole 1986, Prescott et al 1995, Baylor 1996.…”

Information on the habitat requirements and effects of habitat management on wetland birds were summarized from information in more than 500 published and unpublished papers. A range map is provided to indicate the relative densities of the species in North America, based on Breeding Bird Survey (BBS) data. Although the BBS may not capture the presence of elusive waterbird species, the BBS is a standardized survey and the range maps, in many cases, represent the most consistent information available on species' distributions. Although birds frequently are observed outside the breeding range indicated, the maps are intended to show areas where managers might concentrate their attention. It may be ineffectual to manage habitat at a site for a species that rarely occurs in an area. The species account begins with a brief capsule statement, which provides the fundamental components or keys to management for the species. A section on breeding range outlines the current breeding distribution of the species in North America, including areas that could not be mapped using BBS data. The suitable habitat section describes the breeding habitat and occasionally microhabitat characteristics of the species, especially those habitats that occur in the Great Plains. Details on habitat and microhabitat requirements often provide clues to how a species will respond to a particular management practice. A table near the end of the account complements the section on suitable habitat, and lists the specific habitat characteristics for the species by individual studies. The area requirements section provides details on territory and home range sizes, minimum area requirements, and the effects of patch size, edges, and other landscape and habitat features on abundance and productivity. It may be futile to manage a small block of suitable habitat for a species that has minimum area requirements that are larger than the area being managed. The section on brood parasitism summarizes information on intra-and interspecific parasitism, host responses to parasitism, and factors that influence parasitism, such as nest concealment and host density. The impact of management depends, in part, upon a species' nesting phenology and biology. The section on breeding-season phenology and site fidelity includes details on spring arrival and fall departure for migratory populations in the Great Plains, peak breeding periods, the tendency to renest after nest failure or success, and the propensity to return to a previous breeding site. The duration and timing of breeding varies among regions and years. Species' response to management summarizes the current knowledge and major findings in the literature on the effects of different management practices on the species. The section on management recommendations complements the previous section and summarizes recommendations for habitat management provided in the literature. The literature cited contains references to published and unpublished literature on the management effects and habitat requirements of th...

This report is one in a series of literature syntheses on North American wetland birds. The need for these reports was identified by the Prairie Pothole Joint Venture (PPJV), a part of the North American Waterfowl Management Plan. The PPJV adopted a goal to stabilize or increase populations of declining grasslandand wetland-associated wildlife species in the Prairie Pothole Region. To further that objective, it is essential to understand the habitat needs of birds other than waterfowl, and how management practices affect their habitats. The focus of these reports is on management of breeding habitat, particularly in the northern Great Plains.
