Clicking on any image will open the full size image in a new window, so you can study the larger size and then return to the quiz – still in progress – in this window.
Thanks to Martin Reid for allowing the use of his photos (and for counting the birds in each one!).

Wow, all I can say is that nobody should ever listen to me during a Christmas bird count.
Your comment made me laugh outloud, Vanessa! I realize now that the same thing is true for me, too!! :]
Jeez! Same with me!
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.
