Ulleung Island, June 1st-3rd, 2020

Bird news from Leslie Hurteau.

Gargantuan black pigeons, squid, and pumpkin makgeolli; these are the things that stood out to me during my three day stay on the mysterious Ulleung Island. While birdwatchers in Korea like to visit the many Korean islands in the West Sea, well-known for their migrants in spring and fall, Ulleung Island seems somewhat under-appreciated and not often explored for its birdwatching potential. Having a bit of time at my disposal in late spring, I set off for the mysterious island from June 1st to 3rd, 2020, to satisfy my curiosity and hopefully get a chance to see the famed Black Wood Pigeons. 

Leaving from Mukho port, the ferry ride was rather pleasant, with none of the rough seas this ride is sometimes known for. I saw plenty of shearwaters (presumably Streaked Shearwaters) as well as Black-tailed Gulls, and one Grey Heron just off the coast of the mainland. The shearwater numbers peaked around midway of the journey.

Weather on the island was beautiful throughout the entire three days, with a little bit of cloud on the second and third days. I set my base of operations in Jeodong as per recommendation of a friend, and exploration was done mainly on foot, so only a small portion of the island was covered: Jeodong to the Dokdo observatory the first day; Jeodong to Nari Basin the second day; and in and around Jeodong on the third day. The ferry ride on the way back to Pohang was also pleasant and smooth, with sightings of (what were assumed to be) Streaked Shearwaters, as well as Black-tailed Gulls.

Thirty species were seen on the island, with the most common birds being Russet Sparrows, Black-tailed Gulls, Black Wood Pigeons, Grey-capped Greenfinches, Barn Swallows, and Blue Rock Thrush. Unfortunately, no Styan’s Grasshopper Warblers were seen or heard. A more thorough look may have found them, but perhaps it was also a little late in the season for their calls.

The main target species, the Black Wood Pigeon, was fortunately ubiquitous throughout my visit. Over 50 individuals were found on the full second day, and very little effort was required to find them. They were calling regularly, and often found in groups of 3 – 6 individuals, perched on branches sometimes too small for their body weight, with comical results.

Also of note, up to 7 individuals of the local subspecies of White-backed Woodpecker were seen or heard (울도큰오색딱다구리 or Dendrocopos leucotos takahashii). Other potential Ulleung Island subspecies seen included Eastern Great Tits (Parus minor dagetelensis), Varied Tits (Sittiparus varius utsurioensis) and Grey-capped Greenfinches (Chloris sinica clarki). Aside from the White-backed Woodpecker, little information seems to be available on these subspecies and their status, but a Birds Korea writeup addressing the topic can be read here.

A somewhat peculiar sighting was a pair of Common Pochards (one male and female) residing in the Jeodong harbour over the three days. They looked to be in fine form, and it seems likely they were late migrants given it was early June.

Overall it was a pleasant introduction to the mysterious Ulleung Island. A little far to get to, but worth it if the stay is over a few days. It would be interesting to see what species occur at the peak of spring and fall migration, as well as undergoing additional searches for the Styan’s Grasshopper Warblers in the future.

Blue Rock Thrush Monticola solitarius 바다직박구리. Common throughout the island, average 5 – 10 seen on each day.

Russet Sparrow Passer cinnamomeus 섬참새. Very common throughout the island, and it seems to replace the niche that Eurasian Tree Sparrow fills on the mainland. A very rough count of 100 seen over the three days.
