Which Sesame Street scarlet macaw copied Big Bird's words?

Poco Loco was the Sesame Street scarlet macaw who copied Big Bird’s words.

Poco Loco was an anthropomorphic parrot who appeared as a recurring character during the 1970s and early 1980s. His defining behavior was imitation: he repeated words and phrases spoken by other characters, especially Big Bird. That habit often amused Poco Loco but frustrated Big Bird, creating a simple comedy routine built around repetition.

The character was first performed by Jerry Nelson, who also performed many major Sesame Street Muppets. Poco Loco later appeared in additional sketches in which he could imitate sounds such as bells and the voices of other characters. His appearances were relatively brief compared with those of Big Bird, Little Bird, or the human residents of the Street.

A common mix-up is H. Ross Parrot, another parrot character from Sesame Street. The production history also connects the puppets: after Poco Loco’s retirement, his puppet was recycled for H. Ross Parrot and later for another character. Poco Loco is therefore the specific answer to the Big Bird imitation clue, not simply any Sesame Street bird.
