It was a bird of passenger.
A sick Big Apple swan was taken to an animal rescue in the most New York City way possible — the subway.
Good Samaritan Ariel Cordova-Rojas last Thursday brought the suffering swan all the way from Jamaica Bay to Nostrand Avenue station in Brooklyn, where a rehab center took over the bird’s care.
The bird’s presence really caused a flap on the A train, Cordova-Rojas told The Post.
“People were asking me, ‘Oh my god is that a pet? What are you doing with this animal?’” she said. “I told them that I was a wildlife rehabilitator and the swan was hurt and I was taking her to safety.”
