Looks like an ibis in the Florida swampland got spooked by a photog from NJ with an L-series lens ;-) I do like the chaotic sense of fleeing here, it is a breath of fresh air after the usual perfectly sharp bird-in-flight shot. I wish there was a bit more of the story or sense of place visible - if not for the telltale bill it would be tough to see that this is a fairly exotic bird. Also do wish it were in colour, the amount of blur makes you search for the birdie, which is fine...but as always, just my humble .02 cents CDN.
Cool motion shot! The bird almost blends in completely with the background. It's like a "where's waldo" shot, looking for different things within the picture.
