Lewinia

Krick Rail

Lewinia is Ralle species which is represented by three types. These are the Krick Rail, the Aucklandralle and Luzonralle that were formerly placed in the genus Rallus. However, the skeletons of these Coot not coincide with those of the genus Rallus. Other hand, show a superficial resemblance to the gray chest Rail, which now belongs to the genus Gallirallus. Storrs Lovejoy Olson explained in 1973 that the representatives of the genus Lewinia are more primitive than the Pectoral Rail. Olson suggested a close relationship with the much larger Cuvier's Rail ( Dryolimnas cuvieri ) of Madagascar, as the skeletal structure is almost identical. In their bird systematics of 1990, however, Charles Sibley and Burt Monroe were of the view that there is no close relationship between the genera Dryolimnas and Lewinia there. The Coot this genus reach sizes 17-27 inches.

System

Species and their distribution:

• The Krick Rail ( Lewinia pectoralis ) is the type species. It was described in 1831 by Coenraad Jacob Temminck. There are seven extant subspecies, which are common in New Guinea, eastern Australia, South Australia and Tasmania. The subspecies Lewinia pectoralis clelandi from South Australia has not been detected since 1931 and is considered to be extinct.
• The Aucklandralle ( Lewinia muelleri ) was described in 1893 by Walter Rothschild. She was long known only from the type specimen, which was acquired in 1874, before it was rediscovered in 1966. She's on the to the Auckland Islands are islands Adams and Disappointment Iceland Iceland endemic. At times, it was regarded as a subspecies of Common Rail.
• The Luzonralle ( Lewinia mirifica ) was founded in 1959 by Dean Amadon and Kenneth C. Parkes described. It was at times regarded as a subspecies of Common Rail. About their life little is known. The distribution area is limited to the Philippine island of Luzon.
