Bea, I noticed an Osprey on a telephone pole on the Eastern section of Lake Casitas near Santa Ana Road this past week.....years ago they erected a long pole with a platform on the most Eastern section of Lake Casitas... I know of one nest on that platform but for some reason, I no longer see it...

Chat threads are, by their very nature, very unstructured and designed for informal sharing of "off main topics of a forum". To attempt to place structured scientific material, be it general or spacific is self defeating. If you don't want clutter don't expect the chat thread to provide such a platform. Also based on my experiences of the results of numerous forums. This is the main reason why I don't post material to chat threads or rarely read them. Bill  :lol:

I for one thank you for THAT on THIS forum. Whatever happened to your idea of having your OWN forum when you didn't like the way the Wavelit forum was being run and people weren't keeping up with your rules and regulations?

Bea! I like that---Sharpie. I slipped on the eye color. I got so excited when I saw your photos that I wanted to jump in, but have lost my fear of making mistakes. :P

Speaking of teachers. I once had a drawing instuctor, very interesting older guy and we were all "kids" back then. He was complicated and puzzling..."use your mind's eye" was what he used to drill. You'd be going along in one direction and he'd come by your work and say, "now do the opposite." Joseph Barrett--and God bless him, I hope he's an gentle elderly soul still living in Santa Barbara. There are some you just remember, aren't there? I don't recall that he gave specific projects, but that it was an ongoing experience. Those were the days--the late 60's. Draw from the inside out.

Is this an adult Gyrfalcon? (From Tidbits today.)

So, I agree with Ostrich and Patti and say it's a Sharp-Shinned Hawk. I'll further venture a guess and say it's an adult female. The eye-color appears to me more orange-red (female) than deep red (male). Juveniles have pale yellow eyes and white spots on the wing coverts and I do not see that here.

My field guide says the adult sharp-shinned has white underparts with finely barred rufous, whereas the juvenile has "white to light cream with thick reddish-brown streaking, becoming thicker and more barred on the belly". Also the cere is yellow on the juvenile. So although you always have to be a bit careful because of what lighting conditions can do to the photograph, both these also suggest to me an adult. The eyes are dark and the rufous barring on the breast seems to be pretty even and consistent.

Paula, I think, posted a bunch of great Osprey photos a while back. I think? Stills of the nests? Or Bill, too? Tall platforms.

Yep, I'm sure I'm wrong on the juvenile Sharp-shinned now. The underside is pretty rufous in your stills, Bea. Ostrich, I have switched to adult, you know. :D

I couldn't tell the degree of coloring of the iris except to interpret it as "reddish" which supports the adult belief. The eye color does evolve from grey/blue through yellow to red BUT I have never heard, read or experienced anything that ties the coloration to gender. Only to the difference between a 2 year old to a bird nearing or being older than 3 years.
....

Bill, this is quoted directly from the National Geographic "Complete Birds of NorthAmerica":

"The eyes are red-orange (females) to deep red (males)."

The Nat. Geo. book was the only one I consulted for this ID, and I therefore tried to see if I could determine exactly what color the eyes were.
:D

  My experience on several forums and as a teacher of teachers, unfortunately differs from yours. Usually the cause is overworked and lack of time.:lol: Bill  :D

That is to true, but if you feel that way as a teacher I feel sorry for you.
