Kingfisher (川蝉)

On March 16, 2017, a female common kingfisher (川蝉) took more than a minute to swallow a fish at Hatonomori Park in Moriyama City, Shiga Prefecture, Japan (滋賀県 守山市 鳩の森公園).

When I saw her, the fish was head-first in her beak.

She repeatedly gripped the fish at different places along its body. Perhaps she was crushing it to make it easier to swallow.

After swallowing the fish she remained on the same branch for several minutes. She was in the same position when I left.

Technical notes

I shot the video clips and still photos with an Olympus OM-D E-M5 Mark II camera and a Panasonic Leica DG Vario-Elmar f4.0-6.3 / 100-400mm zoom lens at 400mm with lens stabilization (O.I.S.) on. I did not use any special movie mode settings. After a few still photos, I simply pressed the video record button. After the bird flew to another branch, I held the lens on a fence post to reduce camera shake. Fortunately, she remained visible and in focus.

For post-processing I used the free version of DaVinci Resolve 12.5 on a Fedora Linux workstation. Recently I had upgraded my video card to an nVidia GeForce GTX 1060 (6GB), so the software ran smoothly. This professional editing and color grading software works very well, but it has three limitations. First, I could not directly import the video file from my camera. I had to convert the video codec to ProRes, which created huge files (ffmpeg -i kf-1.mov -vcodec prores kf-1-prores.mov). Second, audio does not play without a Blackmagic DecLink card. Audio editing is possible, though, so I edited by sight and listened to the exported video file. Third, export formats are limited to a few formats. For convenience I prefer other editors, but Resolve is great for professional video editing and color grading work on Linux computers.
