Wow, all I can say is that nobody should ever listen to me during a Christmas bird count.

  Me too! I underestimated on every picture, some by as much as 100! I don’t know the method and better read up on it!

It’s so much easier to estimate from a photo than a quickly disappearing flock overhead but practice (and an electronic tally counter) can help.
