Jeju Island, December 4– 5


Birds Information by Leslie Hurteau, with added discourse by Nial Moores

On Sunday November fourth as well as Monday November 5th, time was invested in the area birdwatching with Dr. Nial Moores, that was going to Jeju Island for job associated factors. We began Sunday early morning off on the eastern coastline, where we searched for a lady Canvasback that was found previously in November, probably the very same person that remained in the very same location the previous 2 years. After an incorrect beginning at the incorrect area (oops) we situated the Canvasback at a peaceful area in Seongsan marsh where she had actually been found in 2014. We appreciated the sights till the Canvasback retired on a rock for remainder, providing us our sign to go on to Hado marsh, among the most effective areas for birdwatching on Jeju.

At Hado marsh, we located a large range of wintering waterfowl consisting of types such as the anticipated Eastern Spot-billed Ducks, Gadwalls, Typical Shelducks, North Lapwings, as well as Black-faced Spoonbills (Jeju is still an excellent area for them in winter months), as well as songbirds, such as Pallas’s Reed Buntings, Light-vented Bulbuls, as well as a number of Eastern Yellow Wagtails flying over. Black-faced as well as Masked Pennant calls captured our interest, as well as we waited patiently for them to reveal so we might have the opportunity for an aesthetic contrast. The pennants really did not coordinate, however, yet while waiting an Eurasian Bittern flew over the reeds providing quick sights, as well as an Eastern Buzzard caught a Environment-friendly Sandpiper From the automobile, Dr. Moores found a gull-like bird with a black cap, which might have been the neighborhood Caspian Tern (a varieties in current wintertimes understood to overwinter on the eastern of Jeju). We could not move it, so we made a decision to go on.

From right here we relocated down along the coastline, quiting sometimes to inspect groups of gulls as well as see what shorebirds get on the coastline as well as for any type of feasible seabirds. Mostly Vega Gulls were located, in addition to some Taimyr, Slaty-backed, Mongolian, 2 Saunders’s, as well as one shock Typical Gull (not so usual on Jeju). We made it to Seopjikoji to check the sea for any type of fascinating seabirds. Apart from 2

Black-legged Kittiwakes (seen by NM just), as well as a Pelagic Cormorant or 2, there was not much to create house regarding. On we went a little bit more to some city parks in midtown Seogwipo, the largest city on the south coastline of Jeju. Hyperlinks for eBird lists are right here: Jongdal-ri Breakwater, Jongdal Bay,

A couple of feasible Grey or Tristam’s Buntings were listened to, yet we made a decision to transfer to the last area, Hanon Crater, which is among the only position on Jeju where rice is expanded. A quick search at sundown generated one more feasible Grey

Pennant calling, a feasible Woodcock seen by NM, as well as a Expanse Bean Goose listened to flying over. It was a peaceful finishing to a pleasurable journey along the eastern as well as south shores of Jeju. Hyperlinks for eBird lists are right here: Cheonjiyeon,

We remained in search of a Ryukyu Minivet I had actually found there on November 18th. Good luck got on our side as within minutes of arriving we listened to Ryukyu Minivet calls, as well as quickly found not one yet 2 people (one man as well as one lady) set down high up in a deciduous tree. The sights were quick so we proceeded the search to move them. We listened to the telephone calls a couple of even more times in various places, as well as also had a fast overpass, prior to the minivets came to be silent leaving us with the citizen Warbling White-eyes, Brown-eared Bulbuls, Eastern Tits,

I needed to go on now, yet Dr. Moores remained for a possibility to move the minivets. He moved them later on in the mid-day, as well as not simply 2 yet a team of 7 where the earlier 2 were found, preying on pests in trees, at first low-down with Eastern Great Tits, and afterwards in the cover with

Ryukyu Minivets in Halla Arboretum accompanied 3-4 Ryukyu Minivets seen as well as photographed in Jeonju on the landmass on the very same day, in addition to one more specific seen on the south coastline of Jeju on November 27th. Extra standing note (by NM): Complying with the initial nationwide document located as well as photographed in Might 2013 by Matt Survey, the 6 or two succeeding adequately-documented documents in the ROK of

Ryukyu Minivet currently originated from April as well as Might as well as once again from November as well as December as well as “in the winter months”, with all verified documents to day in the southwest of the Peninsula. There are numerous undocumented insurance claims of “possibles” (consisting of birds I listened to contacting Geoje Island in June 2002) as well as one historic sampling from late September 1915 from Pyonganbukdo, in contemporary DPRK, taken into consideration to be “suspicious” by Austin (1948 ), which was ultimately improperly stated to be in the ROK by Brazil (1991 ). Based upon the pattern of documents in Japan in current years (see listed below) it promises that these current documents of Ryukyu Minivet in the ROK are much more the outcome of array development, partially as a result of the warming environment, than due e.g., to boosted recognition of the types alone– though this obviously will certainly likewise have actually played a significant function as well (i.e., much more knowledgeable birders searching in even more locations with much better cams, permitting the IDs to be verified separately). The Ryukyu Minivet is an instead enigmatic types, which was just split rather just recently from the far more extensive as well as instead similar-sounding as well as similar-looking Ashy Minivet In the area, Ryukyu looks a little shorter-tailed as well as clearly darker over as well as listed below than Ashy, with substantially decreased white on the wing, as well as on the temple. The underparts are likewise cleaned better with grey than in

Ashy as well, as well as the telephone calls are flatter, much less ariose, to my ears seeming even more like a smothered Bohemian Waxwing trill, with the trill extremely commonly duplicated two times in quick sequence. Brazil’s essay on the Birds of Japan (released in 1991) explains Ryukyu Minivet as a resident native to the island to the Nansei Shoto (the islands southern of Kyushu), with a couple of mid-winter “vagrant” documents from Kyushu. By the 1990s, the types was significantly videotaped to the north of its instead slim reproducing array, with groups wintering in woodland in e.g., Miyazaki Prefecture in SE Kyushu, often getting to as much north as Fukuoka Prefecture. Brazil (1991) keeps in mind that Ashy Minivet often wintered in Kyushu, yet in retrospection it appears most likely that the majority of (all?) of these documents most likely would have been Ryukyu Minivet, particularly as the 1974 List of Birds of Japan evidently recommended that Ryukyu was resident in Miyazki Preferecture (see Brazil 1991). In either case, throughout the previous twenty years, the Ryukyu Minivet shows up to have actually been verified as a reproducing types partially of Kyushu, as well as according to the on the internet Birds of the Globe, likewise in western Honshu as well as Shikoku.

Ryukyu Minivet is currently likewise videotaped with some regularity in winter months as much north/east as Tokyo (with all documents on eBird from the Tokyo area originating from September to late March– rather than Ashy Minivet which on eBird has actually just been videotaped in the Tokyo area from April to late October). The seasonal pattern of documents of both of these minivet types in Japan appears instead comparable to the arising pattern in the ROK. Ashy Minivet is a seasonal traveler (April-May as well as very early June?; as well as August to very early November) as well as neighborhood summertime site visitor, located in both chilly pleasant as well as cozy pleasant deciduous as well as combined woodland, with spread reproduction sets across the country throughout the summertime (consisting of over the last few years e.g., an adolescent photographed in very early July in Goheung in 2015; a grown-up in Yeoncheon in very early June 2020; as well as a set in Busan throughout June right into July 2021).

Ryukyu Minivet
shows up mostly to be a winter months site visitor to cozy pleasant combined woodland as well as park– with documents in springtime probably of displaced birds attempting to return southern to the reproducing array. Future colonisation of components of the ROK as a reproducing types appears very potential (particularly in cozy pleasant woodland on Jeju). Based upon the closeness to Japanese reproduction premises, it promises that in the future Ryukyu Minivet will certainly likewise be located in seaside woodland as well as parks in the moderate southeast as well, either as a winter months site visitor or probably also as a local.
