Autumn foliage in Shiga Prefecture 2018
Shiga Prefecture in Japan is blessed with quite a few species of butterflies. A few species are shown here in photographs taken between April and September 5, 2018, when I also made a short video clip (music from “Redwood Highway” by Jason Shaw at AudionautiX.com.)
The video clip and most photos were shot with an Olympus OM-D E-M1 Mark II camera and an Olympus M. Zuiko 40-150mm 2/2.8 PRO lens. A few photos were taken with a Panasonic Lumix DMC-LX9 camera (Japanese monolingual version of LX10/LX15).
All postprocessing was done on a Fedora GNU/Linux workstation. I edited the video clips and added titles with with Kdenlive, but I did not modify the colors or add any enhancements other than slow motion (1/4 speed) from the middle of the clip. Photos were organized and edited with digiKam.
Great egrets (ダイサギ), cattle egrets (アマサギ), and other birds nest in the woods at Hyozu Shrine (兵主大社) in Yasu City, Shiga Prefecture, Japan. I recorded the sounds of the rookery on Sunday, May 27, 2018, and posted a six-minute sample on radio aporee ::: maps and SoundCloud.
The woods are between a large shrine and Yasu City athletic facilities (野洲市中主Ｂ＆Ｇ海洋センター). The white spots in the satellite image of the woods are egrets.
The recording location was not very photogenic. White bird droppings covered everything in the area. On the ground near the tree that held my recorder broken eggshells and a feather indicated young egrets above.
Nests and young birds were hidden in the treetops.
Now and then an adult egret appeared, and I was lucky to see a cattle egret carrying a branch for a nest.
This recording was made with a Sony PCM-M10 recorder and FEL Communications Clippy Stereo EM172 Microphone tied to a tree. Since I was near the south edge of the woods, I placed the mics placed slightly forward of center facing north.
Audio post-processing was done with Audacity on Fedora Workstation, a Linux system running on a Lenovo ThinkStation 20 computer. I trimmed this excerpt from a longer recording and raised the overall volume. No other digital signal processing was done.
On Sunday, March 18, 2018, I was cycling down the north bank of Yasugawa when I heard some noisy crows perched in nearby trees.
When I ride my touring bike, I carry a small audio recorder and microphones. For this recording I used a Sony PCM-M10 recorder and Clippy Stereo EM172 mics by FEL Communications Ltd. To mimic human hearing, a quasi-binaural sound image was made by placing the mics on either side of my bicycle handlebar bag. I prefer to use trees about the diameter of an adult human head, but I use the handlebar bag when I cannot find a tree.
The Compass app on my iPhone shows the location, direction, and time.
As we can see on the map, this location is between a river and near the edge of a suburban area. With aircraft overhead, vehicles on nearby roads, and rural and suburban human activities, this place is quite noisy, even on Sunday.
In everyday life we filter out much of the noise. When the crows are not so noisy, I suppose most people experience this environment as a peaceful and quiet little park, just as it appears in photographs.
Just before noon on January 7, 2017, I made a field recording in a large park along Yasugawa in Shiga Prefecture, Japan (野洲川立入河川公園). The recording was made with a small Sony PCM-M10 digital recorder mounted on a tripod near the lower end of the park. I chose this location in order to reduce traffic and train noises from bridges upstream, as well as the rumble of water at a dam downstream. I pointed the microphones southeast toward Mikamiyama.
We can hear the rumble of a nearby dam, traffic, crows, and kids playing in the distance. These sounds are overwhelmed by a recorded public address message broadcast from speakers on a small building on the embankment above the park. The recorded message asks people to obey park rules: no golf, RC cars or aircraft, fireworks, unleashed dogs, fires, littering, or other activities that may disturb people. The same loud recorded message dominates the sonic environment of the park once every hour.
I often visit this park to look for birds. Egrets, herons, cormorants, and ducks can be found in the river both above and below the dam, and many small birds live in the vegetation along the riverbank.
On January 7th, as I was recording, I walked upstream and saw a few birds.
Activity in this park varies a lot, depending on the season, the weather, and the day of the week. But whatever they are doing, everyone in the park hears the same loud recorded message once every hour.
