Professor Emeritus, Kyoto Notre Dame University (full-time 1977-2014, retired/part-time 2014-). I am mostly retired, but I teach interpersonal and intercultural communication one day a week. I enjoy outdoor activities in Shiga Prefecture, Japan, where I have lived since 1980: cycling, hiking, photography, field recording, and sometimes just wandering around the countryside. Computers and media: I've used Free and Open Source Software on Unix, FreeBSD, and GNU/Linux workstations and servers since the late 1980s. I'm very comfortable with command-line computing, although I enjoy multimedia editing. I very rarely use proprietary operating system, and have no interest in video games.

Uguisu (鶯)

On June 4, 2017, a quiet Sunday, I took a bike ride in Yasu City, Shiga Prefecture, Japan. On the way home I heard a Japanese bush warbler (uguisu, ウグイス, or 鶯).

I always carry a small audio recorder and a pair of Primo EM172 mics in my touring bike handlebar bag. The bird began was sing loudly as I rode into a wooded area, so I quickly leaned my bike against a small tree, attached the mics, and began to record.

The uguisu (Japanese bush warbler) remained in dense foliage, and I never saw any of the birds we hear in this recording. (The photo at the top was taken in 2016.)

This area was once a park. On weekdays dump trucks haul dirt and gravel nearby along the riverbank, but on weekends it’s very quiet, a nice place for leisurely cycling.

Location

The Compass app on my phone shows the direction and location of the stereo recording, but it is not accurate. The mics were aimed south, but the city is Yasu, not Moriyama, and maps coordinates were off by several hundred meters. An annotated paper map or an online map with a satellite image would be more accurate and useful.

This shows the location within the abandoned park.

Recording and post-processing

This method of quasi-binaural recording attempts to emulate human perception by placing the left and right mics on either side of a bicycle handlebar bag. It is not ideal, of course, but setup can be done very quickly. This recording was made with a Sony PCM-M10 recorder and FEL Communications Clippy Stereo EM172 Microphone.

Audio post-processing was done with Audacity on Fedora Workstation, a GNU/Linux system running on a Lenovo ThinkStation 20 computer. I trimmed the recording from more than 20 minutes to 5:19 and normalized the gain. I did not add any filters, EQ, or compression.

This recording is also available on radio aproree ::: maps – sounds of the world.

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.

Grey wagtails (キセキレイ)

In winter I have been delighted to see several grey wagtails (キセキレイ). Here in Shiga Prefecture these beautiful birds are much less common and much more colorful than two other wagtail species, Japanese wagtails (セグロセキレイ) and white wagtails (ハクセキレイ).

In winter I’ve seen grey wagtails most often at Hatonomori Park in Moriyama City (滋賀県 守山市 鳩の森公園). The small stream along the park is an ideal location that I discovered in 2016.

In 2017 the same stream remains a good spot.

Sometimes I encounter grey wagtails along other streams. In December I was able to photograph one as I was cycling along a canal near Hiyoshi Shrine (日吉神社) in Kamitoyama, Ritto City.

Now and then we can see grey wagtails in open areas. After it snowed here in January, 2017, one appeared for several days in Takano Park (滋賀県 栗東市 高野公園).

I am hoping to see more of these beautiful, shy birds before they fly away.

Daurian redstarts (ジョウビタキ)

In late fall and winter many beautiful small birds migrate to Shiga Prefecture in Japan. One of the most colorful species is the Daurian redstart (Phoenicurus auroreus), in Japanese, jōbitaki (ジョウビタキ).

Breeding males are easy to spot: orange chest and lower back, black upper back, head, and neck, grey crown and nape, and very dark brown wings with large white patches. They often perch out in the open, which makes them easy to photograph.

Redstarts are sexually dimorphic. Females are not so colorful. They’re brown above, lighter below, with an orange rump and back-and-orange tail. They’re inconspicuous except in flight. Sometimes they appear in the open, but they tend to stay in or near trees and bushes.

Daurian redstarts seem to be very territorial and easy to spot if you known where to look. I often see a male in a neighbor’s garden, several males and females along the river in Ritto and Moriyama, a male in the Omifuji Botanical Gardens, and a female in a little playground near the JR train tracks in Yasu City. It is always a pleasure to see such beautiful creatures so close to home.
