"The ones in Central Park are icons for the gay community over there," said Ms Hall. "They have a lot of fondness and affection for them.
"It's definitely not an unusual occurrence although this time it's two females."
She said Missy and Penelope have been displaying all the signs of a courting couple in their enclosure, which is home to a dozen of the black and white creatures.
"The thing penguins do to show they like each other is they bow to each other and they are doing that.
"When they come into breeding season, they do it to the penguin of their choice and it reinforces the bond between them.
"It is very sweet to watch."
On Dingle Oceanworld's website, Missy is described as "a fun loving girl, confident and brave".
Penelope, meanwhile, "is a bit shy but absolutely loves swimming, preening, and keeping herself looking clean and beautiful".
