Turtle Doves (キジバト) in Hatonomori Park

On May 28, 2017, a couple of Oriental turtle-doves (キジバト) were mating in Hatonomori Park in Moriyama City (滋賀県 守山市 鳩の森公園).

Earlier a solitary turtle-dove was high in a tree, calling to its mate.

As I was looking for small birds, my wife saw the two turtle-doves and called me. I saw them mating, but I was not able to get a clear view.

By the time I found a place to take photos and video clips, the turtle-doves were taking turns grooming each other.

While I was moving to another position, the two birds separated and then flew away.

The two turtle-doves appeared together for only a few minutes, but I was moved by their mutual affection as I watched them through the viewfinder.

Notes

Video was shot handheld with an Olympus OM-D EM-5 Mk II camera and 40-150mm f2.8 PRO lens with a 1.4x teleconverter.

Music in the video is from “Love Story” (piano) by Sławomir Zając, chafer on SoundCloud (https://soundcloud.com/chafer).

Post-processing was done with Kdenlive running on Fedora Workstation, a GNU/Linux operating system.

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.

Coots – オオバン

On December 29, 2016, several coots (オオバン) were feeding on moss at the base of a flood control dam on Yasugawa about five kilometers upstream from Lake Biwa. Here in Shiga Prefecture, Japan, I often see coots in still water and slow streams, but I’ve never seen them eating so actively. I happened to be carrying a tripod, so I made a short video.

The pool and nearby running water below the dam make this an interesting location. In late spring and summer many people gather to fish there. Cormorants, egrets, and herons hunt nearby, and Japanese kites circle overhead, sometimes swooping down to pluck fish from the river.

Technical notes

Hardware

I shot the opening and closing scenes with an Olympus OM-D EM-5 camera and two lenses: Olympus 17mm f1.8 and Panasonic/Leica 25mm f1.4. For medium, closeup, and extreme closeup shots I used an Olympus OM-D E-M5 Mark II camera and a Panasonic 100-400mm zoom lens.

I used the camera’s optical teleconverter for extreme closeups. At 800mm (400mm x 2) with a micro four-thirds system the 35mm equivalent focal length is 1600mm, which requires a steady tripod. I used a Manfrotto 055XPRO4 tripod and an MVH502AH fluid head. That seems like a lot of tripod for a micro four-thirds system, but it’s great for long lenses. The four-section model is easy to carry. I attach it to my Lowepro Flipside Sport 20L AW, a small backpack that holds two cameras, several lenses, a small audio recorder, etc. Recently I’ve been concentrating on still photography with a handheld camera, so I rarely use a tripod. This experience with the coots reminded me that I should carry a tripod more often.

Video post-processing software

I process media on a Lenovo ThinkStation S20 that runs Fedora GNU/Linux. For this video I first extracted clips from the raw files with FFmpeg. I wrote a shell script to automate processing by reading a data file that specifies how to make each clip.

Video editing was done with Pitivi version 0.97.1. Pitivi has become quite useful and much more stable than the editor I had been using; however, I had to experiment with rendering to get decent output. I used MP4 (x264enc) with a fixed bitrate of 8192K (default is 2048K), and I turned the speed/quality setting OFF (default is medium). Using a good fixed bitrate worked, but I’m not sure why or if my solution is best. Hopefully, future versions of Pitivi will make it easier to produce high-quality output.

Before uploading to YouTube I transcoded the video to Web-optimized M4V with HandBrake. The only trouble I had was that I could not change the title, which was derived from from the filename, and I was not able to edit metadata. (Perhaps it was due to my lack of knowledge.) Before uploading I edited the title and other metadata with the VideoLAN VLC media player.

Swallows Nesting in Ritto City

Barn swallows (ツバメ, 燕) repairing an old nest that was last used in 2014. Morning sunlight strongly backlit the scene, so I used small LED lights to bring out the colors of the birds. Some people are surprised that barn swallows have such beautiful blue heads.

My timing was lucky. The birds had been visiting the nest for nearly a week, but they did all of their repair work on a sunny Saturday morning (April 9, 2016) when I was home. When it was used in 2014, the construction was very smooth, but this time the outer surface near the top is pretty rough.

All scenes were shot handheld in a stairwell with an Olympus MD-D EM-5 Mk. II camera and a 40-150mm f2.8 Pro lens. I did not use any special video settings. I simply pressed the video record button instead of the shutter button. The birds were at the nest only for short periods, so continuous video would have been very difficult without a tripod. I was able to capture a few scenes by starting to record as one of the birds swooped into the car port. In this kind of situation it is easier to shoot still photographs. I shot in bursts at 5 frames per second.

Great Egret Fishing in Oyamakawa

On February 2, 2016, I spotted this great egret fishing in Oyamakawa (大山川) at Omifuji, Yasu City. It was shaking its legs and staring into the water. Apparently, the vibrations drive small fish out where the egret can catch them. I began to take photos, but I switched to video in order to record this way of fishing. While I was recording, the bird stumbled. Usually egrets are more graceful.

This egret is one of very few that have remained in this area in winter. I’m looking forward to March, when more egrets and herons appear in rivers and nearby fields here in Shiga, Japan.

Production notes:

Video and still photos were taken with an Olympus OM-D E-M5 Mk. II and a 40-150 f2.8 PRO lens with a 1.4x teleconverter. I used continuous autofocus with tracking. Sometimes the camera lost the bird and had to refocus the lens.
