The swans of Gorbelgod likely spread to Dol Amroth and are the ancestors of the swans there. Perhaps some original or larger swans would still exist rarely in Meneltarma and Umbar. Pards likely still exist in Rhun, but could be wiped out in places due to their nice fur. Turtles but not giant turtles probably exist. Lastly I think sea serpents are the only other creature on your list that could exist.
