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 in routine tests. This led to the description of two novel species from fish viz "Edwardsiella piscicida" (Abayneh et al., 2013) and "Edwardsiella anguillarum" (Shao et al. 2015) that were previously mis-classified as E. tarda. This might have addressed the arguments between the Japanese and American investigators with regard to the difficulty of differentiating isolates from fish and humans by the time and ended up classifying all into same species i.e. "Edwardsiella tarda". "Edwardsiella tarda" is widely distributed throughout the world. It has been found from the water in Japan all the way to the United States. In Japan it
