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). Link. Fish and Wildlife Service 2016). Avian Conservation Assessment Database [Online]. Birds in Minnesota. 1956. Breeding activity of the nominate subspecies of ruddy duck is centered in the Prairie Pothole Region of North America, as well as the Intermountain West. 2011. It is not uncommon for a Ruddy duck to dive instead of flush when startled or pushed on the water and they do not normally decoy into spreads. 2006)., Raftovich, Robert V., S. C. Chandler, and Khristi A. Wilkins. More recent work in the Great Lakes, however, suggests the species is at least stable to increasing, particularly in the western Great Lakes region. he Pacific Coastal states and the western coast of Mexico winter 55 percent of the ruddy duck population in North America. The male ruddy duck has a brilliant rusty-brown back, rump, neck, scapulars, chest, sides and flanks. 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. The Ruddy Duck was an uncommon species during the Minnesota Breeding Bird Atlas (MNBBA). The primary requirements are extensive beds of emergent vegetation and scattered open water areas that allow enough room for birds to become airborne (Figure 4). 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). No records were documented in northeastern or north-central Minnesota., North American Bird Conservation Initiative, U.S. Committee. © 2020 BirdGuides, Warners Group Publications Plc. 2017. North American Waterfowl Management Plan 2004. Breeding distribution and relative abundance of the Ruddy Duck in North America based on the federal Breeding Bird Survey from 2011 to 2015 (Sauer et al. The male ruddy duck has a brilliant rusty-brown back, rump, neck, scapulars, chest, sides and flanks. Since the Ruddy Duck recovered from its population decline in the late 1800s and early 1900s, its status has remained relatively unchanged. Data collected on the Ruddy Duck, however, are not widely reported but are available for retrieval on the U.S. A short- to medium-distance migrant; most northern populations winter in the central and southern United States and in Mexico. O. j.andina is confined to the Andes of northern and central Colombia, where it is scarce and local. Most birds are late-fall migrants, but there are some reports of overwintering birds. Minneapolis: University of Minnesota Press. More recently, the 2012 update to the North American Waterfowl Management Plan (NAWMP 2012) estimated the mean size of the Prairie Potholes population at 630,000 birds from 2002 to 2011, while the continental population was estimated at 1.2 million birds. The fall migration … As population numbers recovered, the species slowly began to reoccupy much of its former breeding range, from Lincoln County in the southwest corner of the state to Grant and Big Stone Counties in west-central Minnesota, north to Kittson County on the Canadian border. The farthest east the Ruddy Duck was reported was in Dakota, Goodhue, Olmstead, and Ramsey Counties; breeding was confirmed as far east as Hennepin County in south Minneapolis and Freeborn County in southern Minnesota. The bill is dark gray and the legs and feet are grayish. Hertzel, Anthony X., and Robert B. Janssen. Week 1- Sept.15-22 Week 2- Sept. 23-30 Week 3- Oct. 1-8 Week 4- … Roughly 25 percent winter on the eastern coast and 20 percent in the interior of the continent. The bill is dark gray and the legs and feet are grayish.
