The artist – who has been dubbed the Scottish Banksy for his style by some admirers – declined to comment on the new artwork when asked by BBC Scotland.
His Instagram post, showing pictures of it, stated: “The dignified and undignified beasts.
“Located: well, youse (sic) know where.”
It depicts a pigeon reading a pun-filled newspaper, with stories about a seagull gang, a park bench “poop crisis” and a sports story about a pigeon race.
The post was greeted enthusiastically on social media, with comments saying it should win “the Scottish Art of the Year award” and that it should remain permanently in place.
