With their heavy-set bodies, it still comes as a surprise to some that chickens can fly, albeit not very high or far.
One photographer, Adrian Tan, captured this rare sight and shared his pictures on a wildlife photography Facebook page on June 16.
The post has since garnered 1,400 reactions and 4,200 shares.
Flew across the river
Speaking to Mothership, Tan said that he chanced upon this sight on his regular walk at Pasir Ris Park.
During these walks, he takes the opportunity to photograph wildlife.
According to Tan, the chicken "flew diagonally" in order to safely cross to the other side of the river.
Although Tan shared the pictures on June 16, he told Mothership that they were taken at around 8:20am on June 8.
As it was a weekday morning, Tan believes he was the only one at the scene.
When he first spotted it afar, he only recognised it as a "relatively big red-headed white bird".
He only realised it was "a beautiful flying chicken" when the bird flew closer.
Unlike the colourful feathers of the typical red junglefowl that is common in Singapore, this particular chicken appears to be completely yellowish white with red comb and wattle.
