Dalmation Pelican - Pelecanus crispus Dalmation Pelican Listed by IUCN as vulnerable. Conservation measures have resulted in a population increase in Europe, particularly at the species's largest colony, at Lake Mikri Prespa in Greece. However, rapid population declines in the remainder of its range are suspected to be continuing and therefore the species is listed as Vulnerable.
