Trabancos (river) Castile and León (with more than 200 mating pairs). It is also the winter season nesting ground of more than 1,500 red kites ("Milvus milvus"). There are also numerous birds of prey; the most abundant are Montagu's harriers ("Circus pygargus", 50 mating pairs) and lesser kestrels ("Falco naumanni"; almost 150 mating pairs), but there are also hawks, goshawks, falcons, owls, and others. The region is also host to numerous gamebirds, including the red-legged partridge ("Alectoris rufa"). Despite their importance, the population of little bustard ("Tetrax tetrax") in the region appear to be diminishing. Although not all the species protected in
Edwardsiella tarda the world where "E. tarda" is found and they were hoping to discover how similar levels may be in the United States. This could offer scientists a "baseline for the development of more reliable molecular diagnostic tools." The study found that two distinct genotypes do exist within "E. tarda" but does state that it's completely possible that there are more. This study will be used to improve the accuracy of "molecular diagnostics to better understand the role these genetically distinct "E. tarda" groups play in fish health." Abayneh T.
