I first heard of these cameras a few months ago. They're a bit vague about how 
they work, but I got the impression that they use a small aperture to get 
everything in focus, but also somehow encode the distance from the camera to 
each pixel. That allows them to later blur parts of the picture outside the 
chosen focus distance, giving the impression of variable focus.

If that's the case then only slow shutter speeds will be available, not much 
use for bird photos. I may have misunderstood though.
