The resident stork-billed kingfisher (Singapore's largest resident kingfisher) was at the cafe pond sitting nicely on a fallen bamboo stalk. There was also a barrage of megalensed photographers who had set up in the cafe intruding into the king's privacy. It did the best it could by flying off and returning with a fish in its beak only if was facing the opposite direction much to the annoyance of the persons behind some expensive glass.
The bird promptly made quick work of the fish swallowing it. Shortly thereafter, it did a quick neck swing and ruffled its feathers and wings as if to reset itself after the dive to catch the fish. The neck swinging seemed particularly 'violent' ... much more severe than any you might get in an old style barber's chair after a cut. The resetting neck swing shows the power the kingfisher has in its neck muscles when it uses the same action to knock prey (eg. fish, lizards etc.) senseless against branches before swallowing them.
here is the replay of the neck swing (@12.5% normal speed)
