Bustard Bustard Bustards, including floricans and korhaans, are large, terrestrial birds living mainly in dry grassland areas and on the steppes of the Old World. They range in length from . They make up the family Otididae (formerly known as Otidae). Bustards are omnivorous and opportunistic, eating leaves, buds, seeds, fruit, small vertebrates, and invertebrates. Bustards are all fairly large with the two largest species, the kori bustard ("Ardeotis kori") and the great bustard ("Otis tarda"), being frequently cited as the world's heaviest flying birds. In both the largest species, large males exceed a weight of , weigh around 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.
