Winter distribution and oiling of common terns in Trinidad: A further look Winter distribution and oiling of common terns in Trinidad: A further look
Common Terns were studied during January and March 1985 in Trinidad as part of wintering terns in Latin America. Eighty-nine birds were captured, 33 in January, 56 in March. Terns averaged 102 .+-. 0.9 g, with March birds weighing more than those caught in January. This weight is similar to that reported earlier by Blokpoel et al. (1982, 1984) and is considerably less than weights of...

Radiotelemetry locates wintering grounds of DDE-contaminated black-crowned night-herons Radiotelemetry locates wintering grounds of DDE-contaminated black-crowned night-herons
This study was designed to determine if night-herons nesting at Ruby Lake, Nevada, shared a common wintering area with lesser contaminated night-herons nesting farther north in Oregon and Idaho. Radiotelemetry (29 transmitters) and banding studies indicated that the lesser-contaminated Oregon-Idaho night-herons wintered primarily in coastal Mexico (mean 22-23'N latitude), while the Ruby...

Estimating nest detection probabilities for white-winged dove nest transects in Tamaulipas, Mexico Estimating nest detection probabilities for white-winged dove nest transects in Tamaulipas, Mexico
Nest transects in nesting colonies provide one source of information on White-winged Dove (Zenaida asiatica asiatica) population status and reproduction. Nests are counted along transects using standardized field methods each year in Texas and northeastern Mexico by personnel associated with Mexico's Office of Flora and Fauna, the Texas Parks and Wildlife Department, and the U.S. Fish...

Lead concentrations and reproductive success in European starlings Sturnus vulgaris nesting within highway roadside verges Lead concentrations and reproductive success in European starlings Sturnus vulgaris nesting within highway roadside verges
In 1981, the authors studied lead concentrations and reproductive success in free-living European starlings Sturnus vulgaris nesting within the verges of two Maryland highways with different traffic volumes, Route 197(average daily traffic volume[ADT] = 10,800 vehicles) and the Baltimore-Washington Parkway (ADT=52,500 vehicles) and a nearby control area. Concentrations (mg kg-1 dry...

Hatching success of Caspian terns nesting in the lower Laguna Madre, Texas, USA Hatching success of Caspian terns nesting in the lower Laguna Madre, Texas, USA
The average clutch size of Caspian Terns nesting in a colony in the Lower Laguna Madre near Laguna Vista, Texas, USA in 1984 was 1.9 eggs per nest. Using the Mayfield method for calculating success, one egg hatched in 84.1% of the nests and 69.8% of the eggs laid hatched. These hatching estimates are as high or higher than estimates from colonies in other areas.

Dieldrin and endrin residues in fulvous whistling-ducks in Texas in 1983 Dieldrin and endrin residues in fulvous whistling-ducks in Texas in 1983
Fulvous Whistling-Ducks were collected near nesting areas in the rice fields of Texas in 1983 to determine if these birds continue to carry residue levels of organochlorine contaminants, and if the contaminants were acquired in Texas or Mexico. Adults were collected immediately after they arrived from wintering grounds and juveniles were collected in late summer before their departure to...

Potential impacts of agricultural chemicals on waterfowl and other wildlife inhabiting prairie wetlands: An evaluation of research needs and approaches Potential impacts of agricultural chemicals on waterfowl and other wildlife inhabiting prairie wetlands: An evaluation of research needs and approaches
The potential for agricultural chemicals to enter prairie-pothole wetlands and impact wildlife dependent on these wetlands for survival and reproduction appears to be great. However, the actual risk to wetland wildlife from the inputs of these chemicals cannot be adequately assessed at this time, because of insufficient data. Available data on the use of pesticides in the prairie-pothole...
