Monitoring Canadian bird populations with winter counts Monitoring Canadian bird populations with winter counts

Two winter bird surveys in Canada have range-wide population monitoring potential: Christmas Bird Counts (CBCs) and Project FeederWatch (PFW). CBC trends are shown to be correlated to Breeding Bird Survey (BBS) trends, whether or not part of the winter range lies outside the CBC coverage area. Some species are poorly covered by this survey (e.g. seabirds, nocturnal species, and...

Whooping crane mortality at Patuxent Wildlife Research Center, 1982-95 Whooping crane mortality at Patuxent Wildlife Research Center, 1982-95

Whooping cranes (Grus americana) have been reared at Patuxent Wildlife Research Center since 1966. During 1982-95 there were 103 mortalities caused by infectious and parasitic diseases (46%), trauma (21%), anatomic abnormalities (17%), miscellaneous conditions (12%), and open or no diagnoses (5%). The implications that disease may have on new whooping crane flocks in Florida and Canada...

Ecotoxicology of aluminum to fish and wildlife Ecotoxicology of aluminum to fish and wildlife

The toxicity of aluminum has been studied extensively in fish, less so in invertebrates, amphibians, and birds, and not at all in reptiles and free-ranging mammals. For aquatic organisms, Al bioavailability and toxicity are intimately related to ambient pH; changes in ambient acidity may affect Al solubility, dissolved Al speciation, and organism sensitivity to Al. At moderate acidity...

Remarkable saker falcon (Falco cherrug) breeding records for Mongolia Remarkable saker falcon (Falco cherrug) breeding records for Mongolia

During 1994-95 surveys, we located over 80 Saker Falcon (Falco cherrug) breeding sites in Mongolia. Over half of the sites had features that were in some way remarkable or previously undescribed in the scientific literature. Ten were on utility poles, two on bridges, three on abandoned buildings and one was on a truck tire on a pole. Seven sites were very near buzzard nests and two more...

Sources of variation in waterfowl survival rates Sources of variation in waterfowl survival rates

Because of the need to manage hunted populations of waterfowl (Anatidae), biologists have studied many demographic traits of waterfowl by analyzing band recoveries. These analyses have produced the most extensive and best estimates of survival available for any group of birds. Using these data, we examined several factors that might explain variation among annual survival rates to...
