Robustness of survival estimates for radio-marked animals Robustness of survival estimates for radio-marked animals
Telemetry techniques are often used to study the survival of birds and mammals; particularly whcn mark-recapture approaches are unsuitable. Both parametric and nonparametric methods to estimate survival have becn developed or modified from other applications. An implicit assumption in these approaches is that the probability of re-locating an animal with a functioning transmitter is one...

Feeding flights of breeding double-crested cormorants at two Wisconsin colonies Feeding flights of breeding double-crested cormorants at two Wisconsin colonies
Unmarked Double-crested Cormorants (Phalacrocorax auritus ) were followed by airplane from Cat Island and Spider Island, two nesting colonies in Wisconsin, to their first landing site. Cormorants flew an average of 2.0 km from Cat Island (maximum 40 km) and 2.4 km from Spider Island (maximum 12 km). The mean direction of landing sites differed seasonally for flights from Spider Island...

Organochlorines and heavy metals in 17-year cicadas pose no apparent dietary threat to birds Organochlorines and heavy metals in 17-year cicadas pose no apparent dietary threat to birds
Organochlorine and heavy metal concentrations in 17-year cicadas from Prince Georges and Anne Arundel Counties, Maryland, were well below levels known to be harmful to birds. Cicadas contained concentrations of metals similar to or less than other local invertebrates except they contained more copper than did earthworms. Copper and lead concentrations in cicadas from one site may have...

Constraints on productivity of wild Nene or Hawaiian geese Branta sandvicensis Constraints on productivity of wild Nene or Hawaiian geese Branta sandvicensis
I investigated constraints on the productivity of wild Nene on Hawaii and Maui during 1978-81. These populations were composed largely of captive-reared birds. Recruitment of young was low. Of 140 breeding attempts, 36% resulted in successful nests and 7% produced fledglings. Annual productivity was limited because: 1) relatively few available pairs attempted to breed (58% on Hawaii; 46%...
