13 Nov ruddy duck migration
The other long-term data set available on Ruddy Duck populations is the federal Breeding Bird Survey (BBS). Since the Ruddy Duck recovered from its population decline in the late 1800s and early 1900s, its status has remained relatively unchanged. Ruddy ducks are thought to travel at night. During the MNBBA, the species ranked eleventh among the 18 duck species in terms of the total number of records reported. Fish and Wildlife Service. Chartier, Allen T., Jennifer J. Baldy, and John M. Brenneman, eds. Evans, Charles D., and Kenneth E. Black. In California, breeding birds may move to coastal areas. Roughly 25 percent winter on the eastern coast and 20 percent in the interior of the continent. 2017). A diver that feeds primarily on a variety of aquatic invertebrates; small amounts of aquatic vegetation and seeds also are consumed. Summary statistics for the Ruddy Duck observations by breeding status category for all blocks and priority blocks (each 5 km x 5 km) surveyed during the Minnesota Breeding Bird Atlas (2009-2013). The ruddy duck is a member of the stiff-tailed ducks, a fascinating group of eight closely related waterfowl species in the tribe Oxyurini. he Pacific Coastal states and the western coast of Mexico winter 55 percent of the ruddy duck population in North America. Nearly all of the records were within the species’ primary range. Ruddy Duck Identification, All About Birds, Cornell Lab of Ornithology View more species in our Waterfowl ID gallery. More than forty years later, Green and Janssen (1975) summarized the species’ distribution in similar terms, noting that it occurred throughout western Minnesota and east as far as the Twin Cities. Males undergo a molt migration in July away from the breeding grounds before they head to the wintering grounds. During the 2015 season, only 25,727 birds were harvested in the United States, comprising less than 1% of the total duck harvest (Raftovich et al. County Nesting Records of Minnesota Birds. As we near Thanksgiving, many new signs point to a change in seasons. 1987. The conformation of the small ruddy duck is distinctive: a short, thick neck; chunky body; stubby wings and a fan-shaped tail composed of stiff feathers. Laurel, MD: Department of the Interior, U.S. The male ruddy duck has a brilliant rusty-brown back, rump, neck, scapulars, chest, sides and flanks. Breeding distribution of the Ruddy Duck in Minnesota based on the Breeding Bird Atlas (2009 – 2013). Whatever your views on eradication programmes, Alan Tilmouth argues that it is surely time to dispatch the final few Ruddy Ducks left in Britain. The spring migration begins in late February, and continues through May. Migratory Bird Hunting Activity and Harvest During the 2014–15 and 2015–16 Hunting Seasons. Du… 2010. By the year 2000, the population had increased to around 6,000 individuals. Records during Wisconsin’s first atlas appeared to confirm a relatively stable population centered primarily in the Horicon National Wildlife Refuge in south-central Wisconsin (Cutright et al. But like all wetland-dependent species in Minnesota, it will benefit from several conservation initiatives that have been launched in recent years, including Minnesota’s Long Range Duck Recovery Plan (Minnesota Department of Natural Resources 2006) and the Minnesota Prairie Conservation Plan (Minnesota Prairie Plan Working Group 2011). “2015 Waterfowl Breeding Population Survey Minnesota.” In Status of Wildlife Populations, Fall 2015, Wetland Wildlife, edited by Margaret H. Dexter, 95–115. The Minnesota Breeding Bird Atlas Website was a collaborative project led by Audubon Minnesota and the University of Minnesota, Natural Resources Research Institute. The species was observed in 46 of Minnesota’s 87 counties; 4 counties were included because of blocks that straddled county lines: Brown, Dakota, Goodhue, and Scott. Ruddy ducks are thought to travel at night. In 1932 Roberts wrote that in years past the Ruddy Duck was “an abundant breeding bird in all the larger rush-grown and weed-grown sloughs of southern and western Minnesota.” By 1900, however, its numbers were significantly reduced. Its breeding distribution in Minnesota is essentially identical to that reported in the 1930s, but its relative abundance among the 18 duck species that regularly breed in the state has slipped slightly. Birds in Minnesota. *Note that the definition of confirmed nesting of a species is different for Breeding Bird Atlas projects, including the definition used by the Minnesota Breeding Bird Atlas, compared with a more restrictive definition used by the Minnesota Ornithologists’ Union.

They court females by beating their bill against their neck hard enough to create a swirl of bubbles in the water. 1998. “Habitat Use and Nest Success of Overwater Nesting Ducks in Westcentral Minnesota.”, Minnesota Department of Natural Resources. As a result of escapes from wildfowl collections in the late 1950s, they became established in Great Britain, from where they spread into Europe. Small numbers also breed in the interior highlands of Mexico, the freshwater marshes of Baja California, the southern Rocky Mountains and the southern Great Plains. Have you seen something interesting? The Ruddy Duck is one of the last birds to arrive on its breeding grounds each spring (Baldassarre 2014). 2006). High levels of several contaminants, including mercury, cadmium, lead, and zinc, have been found in birds sampled at two key wintering sites, the Chesapeake Bay and the San Francisco Bay (Baldassarre 2014; Brua 2002). 2016). Ruwaldt, James J., Jr., Lester D. Flake, and John M. Gates. View more species in our Waterfowl ID gallery. Flocks of Ruddies wintering on lakes seldom mix freely with other ducks, although they may associate with American Coots. The Ruddy Duck is one of the last birds to arrive on its breeding grounds each spring (Baldassarre 2014). The Andean ruddy duck has the white side of the head spotted with black in varying degrees. Short-distance migrant. “The Use of Prairie Potholes by North American Ducks.” In. If these efforts prove successful, they will have multiple benefits to Minnesota’s Ruddy Duck population. Breeding males are almost cartoonishly bold, with a sky-blue bill, shining white cheek patch, and gleaming chestnut body. The Birds of Minnesota. Because waterfowl surveys are timed to correspond more closely with the nesting phenology of more favored species, such as the Mallard and the Blue-winged Teal, many Ruddy Ducks may still be en route to their final breeding grounds when the survey is conducted. Small numbers also breed in the interior highlands of Mexico, the freshwater marshes of Baja California, the southern Rocky Mountains and the southern Great Plains. Both programs have established aggressive goals for protecting, restoring, and actively managing wetlands in the western region of the state.

Ruddy Ducks migrate in small groups of 5–15 individuals, usually at night. The conformation of the small ruddy duck is distinctive: a short, thick neck; chunky body; stubby wings and a fan-shaped tail composed of stiff feathers. The North American Waterfowl Management Plan has not even established a population goal for the species (Brua 2002). Maxson, Stephen J., and Michael R. Riggs. O. j. jamaicensis (North America, Central America, Caribbean) 650,000; O. j. andina, Andean ruddy duck (High Andes of Colombia) 2,500-10,000; O. j. ferruginea Peruvian ruddy duck (Neotropics) 25,000-100,000 (Rose and Scott, 1994).

Whereas the Ruddy Duck comprised 2% of breeding ducks in the early 1960s, it averaged only 0.6% of the total number of breeding ducks reported from 2011 through 2015 (Cordts 2015).
