HeyGen Voice sample narrates Arctic tern migration fact

Artificial Analysis (@ArtificialAnlys) posted a sample prompt run through HeyGen Voice, a text-to-speech tool, showing a narration about the Arctic tern.

The sample text states that Arctic terns have the longest migration of any animal, flying roughly 44,000 miles a year between the Arctic and Antarctic circles.

The post presents this claim only as the spoken text of a voice sample. It does not include independent sourcing or any statement from HeyGen, and the report provides no evidence that the migration figure has been verified.
