I recently captured a similar series of a pelican taking off from the water. I had not appreciated the fact that to launch like that requires one or more extremely powerful kicks of the webbed feet. A bird can’t simply flap its way into the air from a sitting position. Very nice image.
In the past I posted a series of a swan taking off. If you can find it you will see that it had to take a running start to take off. Other birds that are large or have heavy bodies (e.g Bufflehead ducks) with short wings have the same characteristic take offs.
