Very cool Sanj!
I have posted a couple of these willow tit images on other threads, but this is one where 12 fps came in handy. I wanted the bird in the air, just after it jumps off, with his legs still stretch behind and that first go with the wings.
It builds a nest in the trunk and flies off with the mass it carves out. From the moment I could spot its head in the opening in the trunk, until it was gone on the right side, was 3 frames of head-airborne-tail. With the 5DIII it would have been a tremendous struggle to nail these at that exact time in the air.
