I just wanted to share a quick link with you. I was asked to write a blog post for one of my photo partners, Vanguard Photo US. They asked for some tips for photographing birds of prey, so here it is: http://whytripod.com/photographing-birds-of-prey-with-vanguard-pro-cecil-holmes/
Also, while you are there, check out the entire Wytripod.com site. It has some pretty good stuff on it!
