Bird watchers in New York have welcomed a Mandarin duck to Central Park but have no idea where it's come from.
This East Asian duck usually calls China and Japan home but somehow it's ended up in the middle of the Big Apple.
Spotted initially on October 10 via the Manhattan Bird Alert Twitter page, it has been a constant feature on the page ever since.
According to studies of the Mandarin duck, the fabulous blue, purple, green and gold colours indicate that it is a male.
Ducks are not allowed to be kept as pets in New York, but it has been pointed out that the rubber band around one of his legs says that he belongs to someone.
David Barrett, creator and manager of Manhattan Bird Alert, told the New York Times that there are three ways the duck may have reached Central Park.
"First, he could have escaped from a local zoo. Second, he could have fled captivity somewhere nearby, such as New Jersey. Or third, a duck owner could have tired of having a feathered friend and dumped him in the park."
It was quickly ruled out that the mysterious bird came from any zoos nearby.
Whilst it is not its usual habitat, Mr Barrett told the New York Times that he has faith in the duck's survival.
"Because this type of duck is a 'dabbler', which means it often feeds by moving its bill across the water to find insects and vegetation, it could last in Central Park for a while."
Avid bird watchers are keeping an eye out for the duck and making sure it doesn't get eaten by raptors.
