Effects of liberalized harvest regulations on wood ducks in the Atlantic Flyway Effects of liberalized harvest regulations on wood ducks in the Atlantic Flyway
Beginning in 1977the FWS provided southern Atlantic Flyway states the opportunity to liberalize wood duck harvest regulations. Harvest subsequently increased throughout the flyway but appeared to be more a function of population growth than changes in regulations. In the South, harvest rate increased only slightly for young males and no decline in average survival was detected. We found...

Mercury, cadmium, lead, and selenium in three waterbird species nesting in Galveston Bay, Texas, USA Mercury, cadmium, lead, and selenium in three waterbird species nesting in Galveston Bay, Texas, USA
Heavy metal and selenium concentrations were determined in Olivaceous Cormorants (Phalacrocorax olivaceus ), Laughing gulls (Larus atricilla ), and Black Skimmers (Rynchops niger ) nesting in Galveston Bay, Texas, during 1980-81. Lead was detected at low levels in a small proportion of the liver samples. Mercury was present in all livers sampled, the highest levels being found in...

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.

Lethal Dietary Toxicities of Environmental Contaminants and Pesticides to Coturnix Lethal Dietary Toxicities of Environmental Contaminants and Pesticides to Coturnix
Five-day subacute dietary toxicity tests of 193 potential environmental contaminants, pesticides, organic solvents, and various adjuvants are presented for young coturnix (Japanese quail, Coturnix japonica Temminck and Schlegel). The report provides the most comprehensive data base available for avian subacute dietary toxicity tests and is primarily intended for use in ranking toxicities...

A taxonomic reevaluation of the plain pigeon (Columba inornata) A taxonomic reevaluation of the plain pigeon (Columba inornata)
Three subspecies of the Plain Pigeon (Columba inornata) were described in 1915 from very small samples, and the diagnostic color differences among them were rather minor. Examination of the small series (including two types) of the subspecies in the National Museum of Natural History (USNM) revealed that the quality of most of the material available in 1915 was poor and suggested that...

Aquatic birds and selenium in the San Joaquin Valley Aquatic birds and selenium in the San Joaquin Valley
Kesterton Reservoir is a series of ponds comprising 1,200 acres sitting in the grasslands of the Kesterton National Wildlife Refuge. It is bounded on the east by the San Luis Drain, a concrete-lined canal that discharges agricultural drainage into the ponds at their southern end, from which point it then flows northward through the twelve ponds (see the map on the page following). Mike...
