Regional patterns in proportion of bird species detected in the North American Breeding Bird Survey Regional patterns in proportion of bird species detected in the North American Breeding Bird Survey
Counts from the North American Breeding Bird Survey (BBS) underestimate species richness. We use capture-recapture methods to estimate species richness from BBS count data collected in 1996 and show that detection probabilities demonstrate clear regional patterns. Capture-recapture methods should be used to estimate species richness from count data, and failure to use estimation...

Results of the first ultralight-led sandhill crane migration in eastern North America Results of the first ultralight-led sandhill crane migration in eastern North America
In 1997, we led 8 sandhill cranes (Grus canadensis) south from Ontario, Canada by ultralight aircraft to a wintering area near Warrenton, Virginia, an area without a wild population. Six others were transported south in a trailer in hopes they would return north with those that flew. The migration was 863 km long, included 14 stops, and took 21 days to complete. All 13 surviving birds...

Results of the second (1996) experiment to lead cranes on migration behind a motorized ground vehicle Results of the second (1996) experiment to lead cranes on migration behind a motorized ground vehicle
Fourteen greater sandhill cranes (Grus canadensis tabida) were trained to follow a specially-equipped truck and 12 were led along a ca 620-km route from Camp Navajo in northern Arizona to the Buenos Aires National Wildlife Refuge near the Arizona/Mexico border. Ten survived the trek, 380 km of which were flown, although only a few cranes flew every stage of the route. Major problems...

Results of the Utah-Arizona stage-by-stage migrations Results of the Utah-Arizona stage-by-stage migrations
In an effort to find a safer means of teaching cranes new migration routes, each year (in 1998 and 1999) we transported a group of greater sandhill cranes (Grus canadensis tabida) stage-by-stage, in a horse trailer, with stops for brief flights at about 30-km intervals, along a 1300-1400-km fall migration route from Fish Springs National Wildlife Refuge (Fish Springs) in west-central...

Rodentia and lagomorpha Rodentia and lagomorpha
This comprehensive review examines the extensive literature on wild rodents and lagomorphs as biomonitors of environmental contamination. This chapter covers studies dealing with exposure and effects of environmental contaminants on rodent and lagomorph species, including pesticides (organochlorines, organophosphorus and carbamate compounds, herbicides, plant growth regulators...

The effect of chemical weapons incineration on the survival rates of Red-tailed Tropicbirds The effect of chemical weapons incineration on the survival rates of Red-tailed Tropicbirds
In 1992, the Johnston Atoll Chemical Agent Disposal System (JACADS) began incinerating U.S. chemical weapons stockpiles on Johnston Atoll (Pacific Ocean) where about 500,000 seabirds breed, including Red-tailed Tropicbirds (Phaethon rubricauda). We hypothesized that survival rates of birds were lower in those nesting downwind of the incinerator smokestack compared to those upwind, and...

The effects of semen collection on fertility in captive, naturally fertile, sandhill cranes The effects of semen collection on fertility in captive, naturally fertile, sandhill cranes
We tested to see if semen collection interferes with fertility in naturally fertile pairs of cranes. We used 12 naturally fertile, Florida sandhill crane (Grus canadensis pratensis) pairs for this study, 6 control and 6 experimental. All pairs had previously produced fertile eggs. Semen was collected on Tuesday mornings and Friday afternoons from 26 February 1993 to 4 June 1993. We used
