Can adult birds imprint on humans?

I just saw a youtube short of someone who took a wet crow into their home and dried it and fed it and the comments praising the person to the skies sort of rubbed me the wrong way, but I don't want to have any opinion based on lack of knowledge.

I know baby birds can imprint easily, and that it is irreversible. But can adult birds also imprint? I tried googling this but I didn't find any adult-specific results.

Did the person in the video do something bad, is what I wonder.
