Trumpeter Swans with Cygnets at a wild habitat in Fairbanks

Outside Fairbanks, in a remote lake I noticed two adult swans and two juveniles in the water. Latter, I learned that the swans were Trumpeter Swans which were in the brink of extinction due to heavy hunting. Now they are mostly preserved in captivity and being reintroduced into many of the North American habitats. The trumpeter is the world's largest member of the waterfowl family.
I was happy to see a pair of swans with their juveniles in wild habitat.
