Ecological Distribution and Crude Density of Breeding Birds on Prairie Wetlands

“…study, semipermanent, permanent, and alkali wetlands supported much higher breeding bird densities than we found. The pronounced shift of marbled godwit use from ephemeral and temporary to semipermanent wetlands during drought (Ryan 1982) illustrates this phenomenon. Whether such shifts result from a lack of water in less permanent wetlands, or the appearance during drought of a newly exploitable food resource in the more permanent wetlands, is unknown.…”

Effects of management practices on grassland birds: Marbled Godwit

“…This section is not meant to be a complete bibliography; a searchable, annotated bibliography of published and unpublished papers dealing with habitat needs of grassland birds and their responses to habitat management is posted at the Web site mentioned below. Breeding Marbled Godwits require large expanses of short, sparse to moderately vegetated uplands for nesting and foraging, and wetland complexes for foraging (Stewart 1975, Ryan 1982, Ryan et al 1984, Kantrud and Higgins 1992. Marbled Godwit territories are characterized by a high percentage of grass cover, many wetlands, and high wetland diversity (Stewart 1975, Ryan 1982, Kantrud and Higgins 1992.…”

Marbled Godwit territories are characterized by a high percentage of grass cover, many wetlands, and high wetland diversity (Stewart 1975, Ryan 1982, Kantrud and Higgins 1992. In both upland and wetland habitat, tall, dense cover is avoided (Nowicki 1973, Higgins et al 1979, Ryan 1982, Renken 1983, Ryan et al 1984, Renken and Dinsmore 1987.…”

Marbled Godwits with broods use somewhat taller (15-60 cm), denser grass cover than do nesting pairs (Ryan et al 1984).…”

Riparian ecosystems and their management: Reconciling conflicting uses

“…multivariate statistical methods in studying wildlife habitat is well documented (Shugart 1981, Williams 1983, and these techniques are currently being used extensively (Brown and Batzli 1984, Mannan and Meslow 1984, Munro and Rounds 1985, Pierce and Peek 1984, Ryan et al 1984, Van Horne 1982.…”
