The mute swan, its status, behavior, and history in the U. K The mute swan, its status, behavior, and history in the U. K
For many years the mute swan has been considered a royal bird. It is a prominent resident throughout the United Kingdom (U.K.), often found on the inland waterways. Some people consider it to be a nonmigratory native bird because it doesn't tend to move large distances and doesn't often venture far from freshwater. A mute swan may often live out its life cycle in the same river valley in...

Invasive herbivory: resident Canada geese and the decline of wild rice along the tidal Patuxent River Invasive herbivory: resident Canada geese and the decline of wild rice along the tidal Patuxent River
While concern grows over the increasing numbers of exotic mute swans (Cygnus olor) on the Chesapeake Bay, less attention seems to be given to the highly familiar and native Canada goose (Branta canadensis) which has over time developed unprecedented nonmigratory, or resident, populations. Although nuisance flocks of Canada geese have been well advertised at city parks, athletic fields...

Mute swans: Natural (?) environmental indicators Mute swans: Natural (?) environmental indicators
The rapid expansion of the Chesapeake Bay's population of feral mute swans (Cygnus olar), coupled with a dramatic Bay-wide decline in submerged aquatic vegetation (SAV), has fueled much of the current debate surrounding the need for a management plan to protect the aquatic food resources that are critical to many species native to the Bay. Crucial to this decision process is a sound...

Mute swans and their Chesapeake Bay habitats: proceedings of a symposium Mute swans and their Chesapeake Bay habitats: proceedings of a symposium
The symposium 'Mute Swans and their Chesapeake Bay Habitats,' held on June 7, 2001, provided a forum for biologists and managers to share research findings and management ideas concerning the exotic and invasive mute swan (Cygnus olar). This species has been increasing in population size and is considered by many to be a problem in regard to natural food resources in the Bay that are...
On the trail of Black Scoters On the trail of Black Scoters
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...
