The location of breeding and molting areas of some seaduck species is uncertain, and little is known of seaducks' migrational paths and of habitats used during migration, breeding, and molting. The black scoter is of special concern among the seaducks, because it is both the least common of the three scoter species and the least studied. The Continental Technical Team of the North American Waterfowl Management Plan's Sea Duck Joint Venture recommended that research on this species be conducted to learn more about black scoter movements and to delineate its breeding and molting areas. The team received funding to implant satellite transmitters on this species in Baie des Chaleurs and Restigouche River in New Brunswick, Canada, with the purpose of delineating populations and identifying habitat affinities for staging, breeding, and molting
It’s hard to fathom, but in just 250 years, some 2.5 million acres of coastal prairie that once blanketed in southwest Louisiana have dwindled to just 200 in scattered parcels. The journals of early settlers give us a peek at what it was like: “plentiful game,” “seemingly infinite range for livestock forage,” “long growing season.” As the human population grew, with its concomitant increase in trade, the prairie’s demise ensued. By 1920, overgrazing and large-scale land clearing, primarily for rice production, had reduced the prairie to a fraction of its former self. This loss has had substantial effects on avian species such as Bachman’s, Texas olive, and Henslow’s sparrows, mottled duck, dickcissel, whooping crane, and Attwater’s greater prairie-chicken, now extirpated in Louisiana.
