Asian Koel singing outside my house (with video)

June 19, 2026

A male Asian Koel was calling in front of my house, so I went looking for it and found it singing near the top of a she-oak. A crow came by nearby, which made for a handy size comparison. ^^

A male Large Hawk-Cuckoo calling near the top of a casuarina tree. You can hear them calling all over Ishigaki Island, so use this kind of image to guide your search.

Asian Koel breeding? Black Drongo still present, Ryukyu Scops Owl incubating (video)

May 14, 2024

Hearing an Asian Koel calling, I scanned with binoculars and spotted a male singing from the top of a she-oak. It looked approachable, so I eased the car forward carefully. Even at 100 metres it showed no sign of alarm. I kept closing in. The track ended about 20 metres short, so I continued on foot, using the undergrowth as cover, and managed to get right beneath the she-oak where the Asian Koel was singing. It seemed unaware of me, and I had a close, impressive view of both the bird and its call. Asian Koel have been recorded here before, but from around 2020 the number arriving on Ishigaki Island in May has increased considerably.

After about ten minutes of observation, a female Asian Koel called from a nearby thicket — there appeared to be two individuals. The male then disappeared, seemingly drawn by the female's call, so I searched the area. A Large-billed Crow, thought to be a likely host for Asian Koel brood parasitism, also appeared to be building a nest nearby. This could be a real chance to confirm breeding!!

Black Drongo have been turning up in good numbers across Ishigaki, Okinawa Main Island and elsewhere in the Nansei Islands this season. The peak has passed, but I counted two birds on this day. I think they will be wrapping up soon.

The Ryukyu Scops Owls that breed near my home every year appear to have started incubating again this year. The chicks should fledge in early July.

オニカッコウの鳴き声

May 18, 2020

家族でドライブ中に録音したので、息子の声が入ってしまっています。^^;

ヒヨドリの鳴き声の後ろに「コーエル、コーエル、コーエル、コーエル」と聞こえるのがオニカッコウ(英名Koel)の鳴き声です。

数日前にもほかの場所でオニカッコウの鳴き声を聞いており、今年は石垣島に少なくとも2カ所合わせて3羽が潜んでいることになります。昨年は7月ぐらいまで確認されていたので、2カ月ほどの逗留中に一度ぐらいは姿を拝みたいものです。
