It's hard to imagine how these tiny shorebirds flock without Air Traffic Controllers. There can be crowds of several hundred but they all seem to fly as one, the flock constantly changing shape, size, density and direction. They never seem to bump into each other either. [not sure this qualifies as Blurvision, but adding it anyway]

@nachbar, thanks for spurring me into GIMPing. They can form into clusters (a flock often divides mid-stream) but I don't think your leaf analogy is quite right. They do follow leaders, but the leaders rotate, there's a big advantage to flying in flocks as they can utilize vortex eddies to save energy, but it's simply too tiring for one bird always to be the leader, so leadership rotates (like in a cycling peloton or how cross-country skiiers take turns breaking snowpack or crust).
@Quantumleaper, you're absolutely right, Hummingbirds are incredible, they have absolutely no fear of humans as their metabolisms are approximately 10 times as fast as hours (600 bpm compared to approx. 60 bpm). I think we must look like slow-moving glaciers to them. Perhaps when they hibernate (estivate?) overnight we look like we're moving real-time to them.
Anna, thank you very much [for the fav also], it was my pleasure and I am glad you enjoy them too.
@fdavid, @richy, @dosron - thank you all for the fav.
This picture should really not have worked, luckily I clicked the shutter anyway.
