Wildflowers and Insects

Here in Shiga Prefecture some wildflowers continue to bloom well into November. They attract a variety of flying insects, including butterflies, moths, bees, hoverflies, and wasps.

On November 3, 2018, quite a few insects were feeding along an irrigation canal near rice and soybean fields near my home.

Beet webworm moth (Spoladea recurvalis, シロオビノメイガ
Giant hoverfly (Phytomia zonata, オオハナアブ
Small branded swift butterfly (Pelopidas mathias, チャバネセセリ

Few insects visit tiny flowers such as henbit dead-nettle (ホトケノザ).

Tall goldenrod (セイタカアワダチソウ) grows beside fields and along rivers and ponds. Many species of insects can be seen on goldenrod flowers.

On November 5th, 6th, and 8th, I saw insects on tall goldenrod near the irrigation canal in Tsuji, the riverbank near the tennis courts in Yasugawa Athletic Park (野洲川運動公園), and along Oyamakawa (大山川) in Yasu City.

On November 16th a potter wasp was on tall goldenrod at the reservior near Ono Ramp in Ritto City.

Other flowering weeds compete with tall goldenrod. Bidens pilosa (beggar’s tick, コセンダングサ) yellow disc florets continue to attract bees and other small butterflies after the white ray florets fall off.

Bidens pilosa fruits come off easily and attach themselves to clothing.

Other flowers have continued to bloom and attract insects in November.

After mid-November larger insects such as butterflies are becoming rare.

Egret Rookery

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.

Recording and post-processing

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.

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.

Egrets in September

September at Yasugawa (野洲川) begins gently as the hot, lazy days of summer continue. Great egrets and grey herons stand patiently in and along the river.

As the river rises in early September, we see fewer egrets at popular summer locations such under the Shinkansen (新幹線) bridge.

Many egrets gather at the dam between Yasu City and Moriyama City.

Fall weather begins in early October. Many birds begin to migrate to warmer locations, while some egrets and herons remain at Yasugawa.

January birds

In January, 2017, I took hundreds of photographs of birds near my home in Shiga Prefecture, Japan. Here are a few of them.

More photos are on Flickr. Quality varies!

Selected photos are on 500px.
