contest time!!!

I think I shall have my first ever Pook and Bug contest!  See below for details.

The boys are a bit disappointed that we haven't seen more wildlife than we have.  I think I promised them moose, which has not happened, even in the Tetons.  We have seen:

• elk, which are all over like pigeons around Mammoth Lodge, and scattered here and there everywhere else in the park
• bison, which I am not to refer to as buffalo without hearing Bug correct me
• two pronghorn antelope, which are apparently not really antelope at all
• a bear of some type, although Pook missed it.
• prairie dogs
• trumpeter swans in the Tetons
• mule deer
• llamas (yeah, they were on a ranch, but still...)

So, here is the contest.  Look at the photo below and find the animal.  Something is hiding there.  No, I don't see it either, but it's there!  Leave a guess in the comments and win a prize-ish-like-thing! (Or at least my profound admiration.)
