Caspian Hyrcanian mixed forests an important resting area for birds migrating between Russia and Africa and is thus a key habitat for many bird species. Some outstanding birds that can be found here are the greylag goose ("Anser anser"), white-fronted goose ("Anser albifrons"), Little bustard ("Tetrax tetrax"), glossy ibis ("Plegadis falcinellus"), Eurasian spoonbill ("Platalea leucorodia"), night heron ("Nycticorax nycticorax"), red-breasted goose ("Branta ruficollis"), peregrine falcon ("Falco peregrinus"), Dalmatian pelican ("Pelecanus crispus"), Western cattle egret ("Bubulcus ibis"), squacco heron ("Ardeola ralloides"), greater flamingo ("Phoenicopterus roseus"), white-headed duck ("Oxyura leucocephala"), and Caspian snowcock ("Tetraogallus caspius").

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.
