Ryukyu Minivet Pericrocotus tegimae |
(2017 Edit: Here is the write-up I was asked to do for a Korean ornithological journal:)
Gageo-do,
May 9, 2013
May 9th,
2013, was mostly rainy on Gageo with moderate southwesterly winds – a good sign
after several unproductive birding days, featuring sunny weather and strong
southerly winds. ‘New’ birds spotted in
1-Gu that day included five Japanese
Waxwings, two of which were seen coming in off the sea from roughly the
southwest. Other personal Gageo firsts
in 1-Gu that day were a Yellow-throated
Bunting and a Red-billed Starling. I spotted a total of 54 species on three circuits
of 1-Gu on May 9, compared to just 35 species on May 8.
In the early
afternoon (about 1:30 pm) I was walking through an area of Gageo 1-Gu just
south of the main school. This hilly area
had been highly productive for birds over the previous two weeks, with a good
mix of trees, gardens, scrub and grasses at the edge of town. As I came out from behind a small grove of
trees, I saw a minivet as it flew from one tree to another right in front of
me, at a distance of about 15 feet. I
quickly got a binocular view as it preened and looked around, about nine feet off
the ground, just under the treetops. Although I’d seen many Ashy
Minivets in the area, this minivet immediately struck me as different. The dark grey head and extensive greyish wash
through the breast were the most striking features I noted in the field, and I
felt I was possibly looking at a male Ryukyu
Minivet.
I got several quick
record shots before it flew off, but unfortunately I didn’t hear it call. Based on the quick view I got, I felt I had
something quite interesting, so I went back to my minbak and examined the images. I compared them closely to field guides and
internet images of Ryukyu Minivet and Ashy Minivet. I was fairly confident it was a male Ryukyu
Minivet, based on the grey breast and the markings on the head – the white line
below the eye, relatively narrow white supercilium, and overall dark grey
colour on the head, as opposed to light grey on a female Ashy Minivet. After sending the images to Dr. Nial Moores
(Director of Birds Korea), as well as Dr. Yusuke Umegaki and Yoshiki Watabe
(Japanese bird researchers with field experience of the Ryuku Minivet), they
confirmed the bird as a male Ryukyu Minivet, a species which has been expanding
its range in recent years.
While this sighting
of the Ryukyu Minivet was the first adequately documented record for the ROK,
the species has been previously suspected:
1.
Four minivets heard at Geoje Island on June 4th 2002 (Nial Moores,
Kim Su-Kyoung) were considered to have possibly been of this species.
2.
One presumed individual seen, Geoje Island, June 19th-21st 2003 (Nial Moores)
