Yeah some of his posts were just flat wrong too, but it was like shouting against a hurricane with how popular he was.
He knew his crow stuff, no doubt, but people thought he was like Reddit’s biologist who was an expert on every subfield which of course no one is. But he didn’t seem to want to admit that and instead posted some nonsense.
The short of it is that there was a Reddit poweruser named Unidan who had a background in bird science. Very popular, very often upvoted, tons of karma.
Unfortunately he was found to be vote manipulating on sockpuppets to elevate his content and downvote others, and IIRC this infamous jackdaw copypasta is the one that blew his cover.
