Ecology and management of migrant shorebirds in the Playa Lakes region of Texas
Article Abstract:
The migrant-shorebird species compositions, abundances, migration chronologies, use of habitats and feeding ecologies in the Playa Lakes Region during spring and fall migration were investigated. Invertebrates were the most important components in the diets of several bird species, followed by plant material. Shorebird diet selection patterns differed within individual playas and suggested that the birds used an opportunistic foraging strategy. Shorebird foraging appeared to decrease invertebrate populations in spring but not in fall.

Shorebird habitat use and nest-site selection in the playa lakes region
Article Abstract:
Wetland-scale habitat use and nest-site selection of the four dominant shorebirds, black-necked stilts, killdeer, snowy plovers nesting in playas, saline lakes, and in both created and riparian wetlands in the Playa Lakes Region of Texas, USA are examined. All four species nested in saline lakes and only avocets and killdeer nested in playas and snowy nested in riparian wetlands.

Survival rates of female mallards wintering in the Playa Lakes Region
Article Abstract:
A study of female mallards (Anas platyrhynchos) during 3 winters 1986-1989 in the Playa Lakes Region (PLR) reveals that the survival of mallards is influenced by the body condition during the winter season. Severe winter conditions and poor habitat state lead to the death of birds with poor body condition. Most mallards migrate to the southern section of the PLR in winter.
