2026-08-23: Late summer heat and early migrants on Chuja Island

I took a day trip to Chuja Island to try my luck for seabirds and to see if any migrants are around on the island. The sea was pretty good, with plenty of Streaked Shearwaters and Swinhoe's Storm Petrels, both of which breed on islets between Jeju and the mainland. A large group of Common Terns was spotted on the return boatride, as well.

The island was somewhat quiet as expected, but got a couple Sakhalin Leaf Warblers (confirmed with call), Oriental Cuckoo, and a brief view of a Fairy Pitta (my first visual of one on Chuja). Not a bad visit, but very hot.

2026-07: Jeju City Birds

 A few birds seen around Jeju City in July. Brown-eared Bulbul feeding its young in a tree right in downtown Jeju, Eastern Spot-billed Duck family along the coast, and a Pacific Reef Heron perched nicely in the harbour.

2026-07-02: Dollarbird

 Dollarbirds are regular migrants throughout Korea in spring and fall, and fairly common summer visitors on the mainland of the peninsula. It's somewhat difficult to find them on Jeju in summer as it seems not many stick around. But, I got quite lucky finding a pair this summer in a rural area on the east side of the island. They hung around for several weeks, so it's possible they were breeding.

2026-06-27: Jeju Westside Daytrip

 A bit of a last minute plan to show some visitors the excellent birds around Jeju lead to a very nice early summer day of birding. Highlights included Fairy Pitta, Black Paradise Flycatcher, Oriental Honey Buzzard, and Whiskered Tern. Plenty of regular resident birds were seen well, through a variety of habitats including mountain, forest, coast, and a reservoir. Not too hot yet, still pleasant weather.

2026-06-08: Ducklings and a Bittern

 Late spring can be a good time for migrants still, although pickings are slim by June. Regardless, I got very lucky this morning with excellent views of a Yellow Bittern migrating through. I actually snuck up on it unintentionally, but once I realized what it was I froze and got as many photos as I could and a bit of video. But soon the gig was up and it took one look at me and flew off somewhere a bit further.

Scattered throughout the rest of the coastal wetland were many small ducklings. Eastern Spot-billed Duck is a resident species on Jeju, and often they will have a couple broods each season.

2026-06-03: Mara-do

A daytrip to Mara-do in early June to see what late migrants were out and about. The harbour area was noticeably quieter than before, but with plenty of resident species as well as the summer breeding Barn Swallowsbeing quite active. The boat trip proved to be particularly quiet, both on the way there with basically only two Eastern Spot-billed Ducks seen flying northwards, and the return trip with nothing.

Pacific Reef Heron and Chinese Pond Herons were seen once arriving on the island, as well as a pair of late Richard’s Pipits in the northern end fields. Herons can seem like a theme in late spring on Mara Island, with other related species seen during the day including a group of three Black-crowned Night Herons, Little Heron, and Great Egret.

Regular summer visitors were moving through, including Dollarbird, Black Paradise Flycatcher, Black-naped Oriole, and Tiger Shrike. Ashy Minivet and Oriental Reed Warbler were also encountered, and several brief but good looks at a Common Cuckoo that we ran into a few times on the island.

Late spring generally has few Leaf Warblers and Flycatchers, with only Kamchatka and Dusky Warbler present for the former, and Asian Brown Flycatcher present for the latter. One lone Manchurian Bush Warbler was found singing in the shrubby area in the south of the island, seen very well with the distinct rufous tinged upperparts and pinker legs and bill compared with the more yellowish-brown colours of the locally common Japanese Bush Warbler.

Top spring surprises of the visit would have to be a pair of Red Collared Doves, a species I’ve seen here in late spring before, and a single Chestnut-cheeked Starling. Somewhat unusual in the context of the location was a single feral Rock Dove flying around the island, a species very common throughout the country in developed areas, but personally I have only seen them a few instances on Mara Island.
