Behavior of radio-marked breeding American woodcocks Behavior of radio-marked breeding American woodcocks
During spring 1986-89, we equipped 175 male and 89 female American woodcocks (Scolopax minor) with radio transmitters. Radio-marking had little effect on behavior; within 1 day of marking, 37 of 64 (58%) displaying males were dominant and within 7 days, 138 of 157 (88%) were dominant. All females marked before nesting proceeded to nest, and marked females with broods remained with broods...

Habitat use and survival rates of wintering American woodcocks in coastal South Carolina and Georgia Habitat use and survival rates of wintering American woodcocks in coastal South Carolina and Georgia
Habitat use and survival rates of radio-marked American woodcocks (Scolopax minor) were studied during the winter in coastal South Carolina (1988-89) and Georgia (1989-90). Soon after they arrived, woodcocks were captured in mist nets or in modified shorebird traps or by nightlighting. Each bird was weighed, aged, sexed, and fitted with a 4-g radio transmitter and monitored daily until...

The reintroduction of the Andean condor into Colombia, South America: 1989-1991 The reintroduction of the Andean condor into Colombia, South America: 1989-1991
From 1989 to 1991,22 captive-reared Andean condors Vultur gryphus were released into three protected areas in the Andes of Colombia, South America. The goals of this reintroduction programme were to re-establish populations of these birds in protected habitat where the species had been extirpated, and to train local biologists in the conservation techniques necessary to recover their...

Natal dispersal and gene flow in white-tailed deer in northeastern Minnesota Natal dispersal and gene flow in white-tailed deer in northeastern Minnesota
I documented natal dispersal and gene flow in 79 yearling white-tailed deer (Odocoileus virginianus) in northeastern Minnesota during 1974–1988. Sixty-four percent (n = 28) of 44 males and 20% (n = 7) of 35 females dispersed from their natal home ranges when 1.0–1.5-years old. Eighty-six percent and 95%, of all yearlings including nondispersers, dispersed ≤26 and ≤38 km, respectively...

Natural range expansion and local extirpation of an exotic psittacine--an unsuccessful colonization attempt Natural range expansion and local extirpation of an exotic psittacine--an unsuccessful colonization attempt
The Brown-throated Parakeet Aratinga pertinax is native to Panama, northern South America, and the islands off the northern coast of Venezuela. It is widely believed that the parakeet was introduced to St. Thomas, Virgin Islands, from Curacao before the mid-19th century, although no records exist as to when and how this may have occurred. The parakeet was not recorded from Vieques or...

Research, conservation, and collaboration: The role of visiting scientists in developing countries Research, conservation, and collaboration: The role of visiting scientists in developing countries
As awareness of environmental problems and the need to protect our natural resources or use them wisely has grown, scientists have become increasingly interested in conservation. Some individuals are involved in conservation-related activities through research or teaching, but most of us participate only as citizens concerned about the world in which we live. Often, we decline to take an...

Re-exposure of mallards to selenium after chronic exposure Re-exposure of mallards to selenium after chronic exposure
Adult male mallards (Anas platyrhynchos) were fed a control diet or a diet containing 15 ppm selenium as seleno-D,L-methionine for 21 weeks. After this initial exposure, the mallards were fed untreated food for 12 weeks, then were re-exposed to selenium at 100 ppm for five weeks. During re-exposure to 100 ppm selenium, the birds that had previously been exposed to 15 ppm selenium and...
