Spatula Discors
The blue-winged teal (''Spatula discors'') is a species of bird in the duck, goose, and swan family Anatidae. One of the smaller members of the dabbling duck group, it occurs in North America, where it breeds from southern Alaska to Nova Scotia, and south to northern Texas. It winters along the Pacific and Atlantic coasts and south into the Caribbean islands and Central America. Taxonomy The first formal description of the blue-winged teal was by the Swedish naturalist Carl Linnaeus in 1766 in the twelfth edition of his ''Systema Naturae''. He coined the binomial name ''Anas discors''. A molecular phylogentic study comparing mitochondrial DNA sequences published in 2009 found that the genus ''Anas'', as then defined, was non-monophyletic. The genus was subsequently split into four monophyletic genera with ten species including the blue-winged teal moved into the resurrected genus ''Spatula''. This genus had been originally proposed by the German zoologist Friedrich Boie in 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pea Island
Pea Island is an island which is part of the Outer Banks of North Carolina. Because of the shifting nature of the barrier island system of which Pea Island is a part, and the way in which inlets open and close over time, Pea Island has, at times, been contiguous with the neighboring Bodie Island to the North and Hatteras Island to the south. Pea Island was created when two inlets, the New Inlet in 1738, and Oregon Inlet in 1846, separated it from the neighboring islands. The island was rejoined to Hatteras Island intermittently from 1922 until 1945 as the narrow New Inlet opened and closed with shifting sands. From 1945 to 2011, Pea Island was merely the northern 11 miles or so of Hatteras Island. Hurricane Irene reopened the New Inlet, making Pea Island separate again, although New Inlet has since closed reconnecting it with Hatteras. Pea Island was home to the Pea Island Life-Saving Station, the first U.S. Coast Guard life-saving station to have an all African-American ...
