It was about 30 below today so I sat in my car beside a thickhedge full of Jays. They were trying to protect themselves from the wind and coldwith the branches so manual focus was necessary to capture anything at all. Here are a few:

Peek-a-boo 1



Peek-a-boo 2



Side glance bathed in snowflakes



Side glance catching a peek of sunlight



Here are a fewshots of a Jay fluffing feathers for warmth (some backlighting)





So that's what it's been like for Jays of the North today.

Quite the thicket to be photographing into. I've got to try manual focusing on some of the smaller birds near my house that roost in much the same type of shrubbery.

Best one is #2, just because the jay is holding something in its bill.

Good shots through the thickets. I like the first one. The look on the face
and the chest puffed out makes him look like a tough guy!

I'm increasingly amazed at how much bad weatherthese birds can take and I've been reading up lately on how their systems handle it. However, I have not yet found out how their tiny feet don't freeze so if anyone out there knows the answer to this I'd be interested to know.

My parents tell me stories of when they lived in England (they were raised there) they would see birds sitting on power lines frozen to death and Dad actually once saw a frozen dead sheep still standing up, it must have been really cold.

You'll love these links with some explanations, Norm...

And at this link:
http://realscience.breckschool.org/u...er/winter.html, here is a synopsis:
Quote:
Most of us have marvelled at how ducks and geese can stand around on a frozen lake or swim in frigid waters. In addition to the limb adaptations described above, these and other species have another method of minimizing heat loss--a countercurrent heat exchanger made up of a special network of blood vessels known as the rete mirabile. Simply explained, incoming and outgoing vessels in the legs are in close proximity. As a result, heat from the warm blood flowing out is transferred to the cold blood going in. By the time the blood returns to the body, it is almost as warm as the blood going out. This, coupled with intermittent vasoconstriction and vasodilation, allows them to keep the feet at a cold but safe level.

Anyways, some good reading for you for a cold New Year's Eve! Happy New Year's Norm!

Great focusing in difficult conditions. The light is also amazing. You also capture the cold!!

Man, it is cold out there. I think I should quit complaining about the rains we have been having for a week or so.
