White-tailed eagle at . However, this is dwarfed by the largest avian prey credited to a white-tailed eagle, an adult male great bustard ("Otis tarda"), which weighed an estimated (which, much like exceptionally large fish taken, must have been consumed in the killing spot or subsequently dismantled as too large to fly with). Among the land birds taken, more than 20 passerines are included in the prey spectrum but most are obviously too small and swift to be anything but incidental prey. The smallest avian prey known for white-tailed eagles was a great tit ("Parus major"), a species which weighs on average.
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.
