Group:
Would a Rough Legged Hawk begin to form light patches at its wing "elbows"
at this time of year? If you my question is unclear, and you are curious as
to what I am inquiring, please contact me directly and I will be more
specific. Thank you.

Greetings,
I spent a couple hours at Myers again this morning. Highlights
included fly over WHIMBREL and BLACK-BELLIED PLOVER. Both birds were
quite high and I don't think I would have seen them if they had not
been calling. In fact, I never could find the plover in the bright
blue sky even though

This is the man we have to thank for modern optics.
He not only invented the scientific method of testing, but among his many
accomplishments, determined how light rays focus at a point.
