Little egret hunting in a canal

On October 14, 2017, I saw a little egret in the canal that runs around my neighborhood. It was hunting by shaking a leg to drive prey from vegetation in the shallow water. As I was returning on foot from a long photo walk, my camera was ready. I was able to shoot a few minutes of video before the bird walked away up the canal.

I also took several photos, but still photography cannot show the egret’s quick leg movements.

Butterflies in September


September is a great month to watch butterflies and other insects on flowers in rural Shiga Prefecture, Japan. Between August 31 and September 21, 2017, I photographed ten species and saw several others while cycling in the countryside near my home.

Notes

Please let me know if you see errors in the photo captions. I have only recently learned the names of some butterflies and flowers shown here.

Most photos were shot with an Olympus OM-D E-M5 Mark II camera and an M.ZUIKO DIGITAL ED 40-150mm F2.8 PRO lens with a 1.4x Teleconverter MC-14. Usually I shoot with Auto-ISO in shutter priority mode. For wide-angle and medium shots I use a Panasonic LUMIX DMC-LX9 (Japanese-only version of LX10/LX15).

Sounds of cicadas at the end of summer

Along Oyamakawa in Omifuji, Yasu City, Shiga Prefecture, cicadas dominate the soundscape in summer. In mid-September, before autumnal equinox, smaller insects join the chorus.

On 2017-09-15 the cicadas were very loud as I rode my mountain bike on a path through a grove of ornamental cherry trees between a small river and a residential neighborhood (radio aporee ::: maps – Omifuji, Yasu-shi, Shiga-ken, Japan).

Audio recorder and microphones

A little before 13:00 I mounted a Sony PCM-M10 recorder and FEL Clippy EM172 mics on a tree trunk for quasi-binaural recording. The mics face northwest toward a busy two-lane road, Japan national route 8, with the river and farms to the right and a residential neighborhood to the left.

We can hear cars, trucks, agricultural machinery (rice harvester), and other human sounds, but the cicadas compete well and nearly drown out the songs of smaller insects. Soon the cicadas will fall silent, and we’ll wonder how another summer passed so quickly.

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.
