The note for the video element reads:

  In particular, this content is not intended to address
  accessibility concerns. To make video content accessible to the
  blind, deaf, and those with other physical or cognitive
  disabilities, authors are expected to provide alternative media
  streams and/or to embed accessibility aids (such as caption or
  subtitle tracks) into their media streams.

What would then be the recommended way to provide fallback content
for a video like the following?

That's a 6-second video of a Red-and-green Macaw moving along a
tree branch, with the only sounds being it making a brief
vocalization, and some background sounds. It doesn't seem to lend
itself either to fallback content provided by alternative media
streams or by embedded captions or subtitles.
