I spotted this pair of Cedar Waxwings,
Bombycilla cedrorum, almost straight above me in a dead Red Pine tree. When surprises like this happen, I almost can't believe it! This is heart-pounding stuff! Okay, I had to buckle down and get the shots off. Autofocus was going beserk with those intervening branches. I knocked off the AF and slowed down, stayed still, and got off all the photos I could. Then I realized that these birds weren't that spooky so I moved around a bit.

There was a good bit of behavior where it looked like one had its beak in the other's. My Audubon guide tells me that they are very social and like to pass berries around, sometimes down a long line of them!

Waxwings are exclusively fruit eaters and have been known to become intoxicated from eating fermenting berries. No, this one's not staggering off the limb but launching up to another branch.

And here's where the waxwing gets it's name--those hard, red, wax-like tips on the secondary feathers.

In this shot, I noticed a curious little hook on the tip of the beak.

I have recently observed what I had thought to be Mourning Doves in flight, but due to their agile gliding and cornering, I suspect I have been witnessing waxwings. The behavior just didn't seem quite right for a dove.
