The management of hunting of Anatidae The management of hunting of Anatidae
The objectives of harvest management for members of family Anatidae typically involve the size of the harvested population and the size of the harvest. Hunting regulations are the primary tool used to try to achieve the objectives of harvest management. Informed harvest management thus requires a knowledge of the relationship between hunting regulations and both Anatid abundance and...

Diurnal raptors in the fragmented rain forest of the Sierra Imataca, Venezuela Diurnal raptors in the fragmented rain forest of the Sierra Imataca, Venezuela
The rain forest of the Sierra Imataca in eastern Venezuela has been subjected to extensive deforestation for pastures and agricultural settlements. In the last decade the opening of access roads combined with intensified logging and mining activities have fragmented a significant portion of the remaining forest. We noted local distribution and habitat use for 42 species of diurnal...

Evaluation of 3 radio transmitters and collar designs for Amazona Evaluation of 3 radio transmitters and collar designs for Amazona
I evaluated 3 radio transmitter attachments and designs for adult parrots. Two of the transmitters and attachments were similar to those used previously in the study on fledgling and adult parrots. I designed, in collaboration with the manufacturer, a third transmitter and attachment that provided protection of key areas from chewing and eventual destruction of the attachment or...

Cytochrome P450 and contaminant concentrations in nestling black-crowned night-herons and their interrelation with sibling embryos Cytochrome P450 and contaminant concentrations in nestling black-crowned night-herons and their interrelation with sibling embryos
Hepatic cytochrome P450-associated monooxygenase activities were measured in 11-d-old nestling black-crowned night-herons (Nycticorax nycticorax) collected from a reference site (next to Chincoteague National Wildlife Refuge, VA, USA) and three contaminated sites (Cat Island, Green Bay, WI, USA; Bair Island, San Francisco Bay, CA, USA; and West Marin Island, San Francisco Bay, CA, USA)

The proper name of the neotropical tree boa often referred to as Corallus enhydris (Serpentes: Boidae) The proper name of the neotropical tree boa often referred to as Corallus enhydris (Serpentes: Boidae)
Confusion regarding the application of the proper scientific name for the common Neotropical tree boa has existed since Linnaeus described Boa enydris and Boa hortulana in 1758. We review the nomenclatural history of the species and point out the misapplication of scientific names that have characterized this form. Our review indicates that the proper scientific name for this highly...

Habitat associations of birds in the Georgia piedmont during winter Habitat associations of birds in the Georgia piedmont during winter
During three winter seasons (1991-1994), we studied the distribution and abundance of birds in three habitat types of the Georgia Piedmont. Bird densities were calculated using data from 2160 variable circular-plot counts, 720 each in the interiors of the three habitats. Habitat variables were measured in 135 0.04-ha circles, 45 in each of the three habitats. The objective was to compare...
