One of my favorite subjects - and a whole freakin' slew of them at that! I really like the way this is so incredibly messy yet strikingly simple if that makes sense.
I agree with Germaine.. indeed nice job stopping the action.. and I too wish it were a bit brighter.. one of the reasons for that is because you did such a great job stopping the birds that I just know there would be wonderful detail in their wings..I nearly missed the bird in front of the woman - looks like it might be a near perfect silhouette and having her clothes a bit brighter would frame it more effectively.
Wow, this is soo cool. Your black and white photography is great, but I think this is my favorite from your portfolio. Sorry I have nothing more constructive to say. Wow.
