The next behavior is also one that we saw over and over throughout the morning. Adults and younger birds would get up on the highest perch out there and while calling in a loud, raspy cry, they would throw their heads back until it almost would touch their shoulders. I shot several sequences of this.

I have read several resources to see what this is all about, but cannot get a definitive answer. Some say it is a courtship ritual and others say it is more of a territorial display.

And I think the image of the last behavior I captured speaks for itself. No words needed. Where's that winking smiley when you need it?
