Can you count the hawks?

A couple of days past a good many hawks flew over the Cow Barn.  The noted ones passed mostly between 10-10:20 with stragglers until 10:30.   We may have missed (not noted) a few before 10, but maybe not.

It's fairly hard to count hawks.  Crumby thinks, typically, counts are too high, perhaps due to the excitability of the enumerator.  But if a camera is handy,  a picture can make the count easier and more accurate.  This is the third, and largest, kettle that passed over around 10:20 AM.
