Geoff, Matt & IBET -

Thanks ever so much for this very interesting, nuanced and informative
feedback! In fact, I have had the pleasure of somewhat knowing Geoff for
many years and birding with him a few times. In addition to his posts, each
time I am in awe of how much Geoff knows about birds. It is not his
intention since he is a wonderful gentleman, but I feel like a novice next
to him which is great since I love to learn. This is just another example
that makes me realize even after many years of birding, I still have a ton
to learn.

Thanks ever so much to IBET too. I am not on Facebook for a number of
reasons, so I greatly appreciate this forum, birders of all levels and the
sharing of knowledge!
