Black swans, which also feature a distinctive red bill, are native to Australia.
But the highly nomadic birds are now more frequently being spotted outside their usual climes, due at least in part to escapees from wildfowl reserves making their home in nearby wetland areas.
West Belfast man Pat Hall is a keen birdwatcher and, when he heard about the latest visitor to the Waterworks, had to see for himself.
"I like watching and taking photos of birds, so I said I'd have to come over and see what the craic is," he told UTV.
"I'd never heard of it before and couldn't wait to see it. Delighted."
And he certainly wasn't the only one to be impressed by the beautiful sight.
Martin O'Neill has been visiting the park every day for years, often stopping to feed the birds.
"I saw two black swans about 10 years ago," he told UTV.
"But it is a novelty - a lot of children will never have seen a black swan in their lives."
