All images taken in 2025, unless otherwise noted.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Summer birding on Jeju, and the whole of Korea really, can be particularly unpleasant with high humidity, oppressive heat (getting hotter in recent years), and periods of heavy rainfall. So it&#8217;s no surprise that the winter months and migration periods are more popular with birders. However, there&#8217;s a lot to be found in the summer that makes Jeju very special, and overall helps Korea standout both in East Asia and globally in the birding world.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Since summer birding on Jeju isn&#8217;t as popular as the other seasons, I would like to share some of the summer birding highlights one can expect in Jeju from June to July. Hopefully to make the season more appealing and encourage other birders to get out and find those summer specialties. There is a lot to cover, including many breeding resident species, so I will stick strictly to the summer visitors. This is by no means meant to be comprehensive and only covers what I personally have found through birding on Jeju for four years (and counting). I&#8217;m positive there are more surprises waiting.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"720\" src=\"https:\/\/www.birdskoreablog.org\/wp-content\/uploads\/2025\/08\/P2530490-1024x720.jpg\" alt=\"\" class=\"wp-image-30953\" srcset=\"https:\/\/www.birdskoreablog.org\/wp-content\/uploads\/2025\/08\/P2530490-1024x720.jpg 1024w, https:\/\/www.birdskoreablog.org\/wp-content\/uploads\/2025\/08\/P2530490-300x211.jpg 300w, https:\/\/www.birdskoreablog.org\/wp-content\/uploads\/2025\/08\/P2530490-150x105.jpg 150w, https:\/\/www.birdskoreablog.org\/wp-content\/uploads\/2025\/08\/P2530490-768x540.jpg 768w, https:\/\/www.birdskoreablog.org\/wp-content\/uploads\/2025\/08\/P2530490-1536x1080.jpg 1536w, https:\/\/www.birdskoreablog.org\/wp-content\/uploads\/2025\/08\/P2530490.jpg 2000w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\"><strong>Fairy Pitta<\/strong> <em>Pitta nympha<\/em> <strong>\ud314\uc0c9\uc870<\/strong><\/figcaption><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Among local birders, summer birding on Jeju mainly revolves around <strong>Fairy Pittas<\/strong> and <strong>Black Paradise Flycatchers<\/strong>. Both species arrive on Jeju around May and stick around until September or so. They are fairly common in similar habitat, mainly thick forests (gotjawal \uacf6\uc790\uc648), forested volcanic hills (oreum \uc624\ub984), and steep rocky valleys on the slopes of Hallasan. Finding them can be difficult and often are heard only, mainly because both species are very shy, and their preferred habitat makes for challenging birding (poor light and many plants!).<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"730\" src=\"https:\/\/www.birdskoreablog.org\/wp-content\/uploads\/2025\/08\/P2530550-1024x730.jpg\" alt=\"\" class=\"wp-image-30954\" srcset=\"https:\/\/www.birdskoreablog.org\/wp-content\/uploads\/2025\/08\/P2530550-1024x730.jpg 1024w, https:\/\/www.birdskoreablog.org\/wp-content\/uploads\/2025\/08\/P2530550-300x214.jpg 300w, https:\/\/www.birdskoreablog.org\/wp-content\/uploads\/2025\/08\/P2530550-150x107.jpg 150w, https:\/\/www.birdskoreablog.org\/wp-content\/uploads\/2025\/08\/P2530550-768x547.jpg 768w, https:\/\/www.birdskoreablog.org\/wp-content\/uploads\/2025\/08\/P2530550-1536x1094.jpg 1536w, https:\/\/www.birdskoreablog.org\/wp-content\/uploads\/2025\/08\/P2530550.jpg 2000w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\"><strong>Black Paradise Flycatcher<\/strong> <em>Terpsiphone atrocaudata<\/em> <strong>\uae34\uaf2c\ub9ac\ub531\uc0c8<\/strong><\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"764\" src=\"https:\/\/www.birdskoreablog.org\/wp-content\/uploads\/2025\/08\/P2540659-1024x764.jpg\" alt=\"\" class=\"wp-image-30961\" srcset=\"https:\/\/www.birdskoreablog.org\/wp-content\/uploads\/2025\/08\/P2540659-1024x764.jpg 1024w, https:\/\/www.birdskoreablog.org\/wp-content\/uploads\/2025\/08\/P2540659-300x224.jpg 300w, https:\/\/www.birdskoreablog.org\/wp-content\/uploads\/2025\/08\/P2540659-150x112.jpg 150w, https:\/\/www.birdskoreablog.org\/wp-content\/uploads\/2025\/08\/P2540659-768x573.jpg 768w, https:\/\/www.birdskoreablog.org\/wp-content\/uploads\/2025\/08\/P2540659-1536x1146.jpg 1536w, https:\/\/www.birdskoreablog.org\/wp-content\/uploads\/2025\/08\/P2540659.jpg 2000w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\"><strong>Fairy Pitta<\/strong> <em>Pitta nympha<\/em> <strong>\ud314\uc0c9\uc870<\/strong><\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"715\" src=\"https:\/\/www.birdskoreablog.org\/wp-content\/uploads\/2025\/08\/P2540590-1024x715.jpg\" alt=\"\" class=\"wp-image-30960\" srcset=\"https:\/\/www.birdskoreablog.org\/wp-content\/uploads\/2025\/08\/P2540590-1024x715.jpg 1024w, https:\/\/www.birdskoreablog.org\/wp-content\/uploads\/2025\/08\/P2540590-300x209.jpg 300w, https:\/\/www.birdskoreablog.org\/wp-content\/uploads\/2025\/08\/P2540590-150x105.jpg 150w, https:\/\/www.birdskoreablog.org\/wp-content\/uploads\/2025\/08\/P2540590-768x536.jpg 768w, https:\/\/www.birdskoreablog.org\/wp-content\/uploads\/2025\/08\/P2540590-1536x1072.jpg 1536w, https:\/\/www.birdskoreablog.org\/wp-content\/uploads\/2025\/08\/P2540590.jpg 2000w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\"><strong>Fairy Pitta<\/strong> <em>Pitta nympha<\/em> <strong>\ud314\uc0c9\uc870<\/strong><\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Fairy Pitta \/ Pitta nympha \/ 2025-07-17, Jeju, Korea\" width=\"690\" height=\"388\" src=\"https:\/\/www.youtube.com\/embed\/eMqUWJljHhI?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Other species that are easier to find in similar habitats are <strong>Grey-backed Thrush<\/strong> and <strong>Yellow-rumped Flycatchers<\/strong>, the latter tending to be more common in forests at higher elevations on Hallasan.

It&#8217;s about halfway between Jeju and the mainland, and feels more like one of the many islands off the south coast of the mainland rather than Jeju proper. Any visitor familiar with the two regions would pick up on this immediately simply by seeing the lack of black volcanic rock Jeju is famous for. With that in mind, the birds seem to be a bit more of a mix between mainland and Jeju. For instance during one visit in mid July&nbsp; 2025, I found groups of <strong>Tiger Shrikes<\/strong>, with juveniles present, indicating breeding. This species is quite rare on Jeju proper outside of spring and fall migration, so it was an interesting find. Other summer visitors seem to be the ubiquitous <strong>Grey Backed Thrush<\/strong>, <strong>Pale Thrush<\/strong> (also present in winter), Pacific Swift, and plenty of Barn Swallows. I have also seen East Asian Finless Porpoise here, a marine mammal that is generally not present along the coast of Jeju proper. The island is seemingly rarely birded, much like many of the nearby islands along the southwest and south coast of the mainland, so additional visits may reveal more surprises.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"786\" src=\"https:\/\/www.birdskoreablog.org\/wp-content\/uploads\/2025\/08\/P2540857-1024x786.jpg\" alt=\"\" class=\"wp-image-30963\" srcset=\"https:\/\/www.birdskoreablog.org\/wp-content\/uploads\/2025\/08\/P2540857-1024x786.jpg 1024w, https:\/\/www.birdskoreablog.org\/wp-content\/uploads\/2025\/08\/P2540857-300x230.jpg 300w, https:\/\/www.birdskoreablog.org\/wp-content\/uploads\/2025\/08\/P2540857-150x115.jpg 150w, https:\/\/www.birdskoreablog.org\/wp-content\/uploads\/2025\/08\/P2540857-768x589.jpg 768w, https:\/\/www.birdskoreablog.org\/wp-content\/uploads\/2025\/08\/P2540857-1536x1179.jpg 1536w, https:\/\/www.birdskoreablog.org\/wp-content\/uploads\/2025\/08\/P2540857.jpg 2000w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\"><strong>Tiger Shrike<\/strong> <em>Lanius tigrinus<\/em> <strong>\uce61\ub54c\uae4c\uce58<\/strong><\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"714\" src=\"https:\/\/www.birdskoreablog.org\/wp-content\/uploads\/2025\/08\/P2540843-1024x714.jpg\" alt=\"\" class=\"wp-image-30962\" srcset=\"https:\/\/www.birdskoreablog.org\/wp-content\/uploads\/2025\/08\/P2540843-1024x714.jpg 1024w, https:\/\/www.birdskoreablog.org\/wp-content\/uploads\/2025\/08\/P2540843-300x209.jpg 300w, https:\/\/www.birdskoreablog.org\/wp-content\/uploads\/2025\/08\/P2540843-150x105.jpg 150w, https:\/\/www.birdskoreablog.org\/wp-content\/uploads\/2025\/08\/P2540843-768x536.jpg 768w, https:\/\/www.birdskoreablog.org\/wp-content\/uploads\/2025\/08\/P2540843-1536x1071.jpg 1536w, https:\/\/www.birdskoreablog.org\/wp-content\/uploads\/2025\/08\/P2540843.jpg 2000w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\"><strong>Tiger Shrike<\/strong> <em>Lanius tigrinus<\/em> <strong>\uce61\ub54c\uae4c\uce58<\/strong><\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"647\" src=\"https:\/\/www.birdskoreablog.org\/wp-content\/uploads\/2025\/08\/P2550020-1024x647.jpg\" alt=\"\" class=\"wp-image-30965\" srcset=\"https:\/\/www.birdskoreablog.org\/wp-content\/uploads\/2025\/08\/P2550020-1024x647.jpg 1024w, https:\/\/www.birdskoreablog.org\/wp-content\/uploads\/2025\/08\/P2550020-300x190.jpg 300w, https:\/\/www.birdskoreablog.org\/wp-content\/uploads\/2025\/08\/P2550020-150x95.jpg 150w, https:\/\/www.birdskoreablog.org\/wp-content\/uploads\/2025\/08\/P2550020-768x485.jpg 768w, https:\/\/www.birdskoreablog.org\/wp-content\/uploads\/2025\/08\/P2550020-1536x971.jpg 1536w, https:\/\/www.birdskoreablog.org\/wp-content\/uploads\/2025\/08\/P2550020.jpg 2000w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\"><strong>Pale Thrush<\/strong> <em>Turdus pallidus<\/em> <strong>\ud770\ubc30\uc9c0\ube60\uadc0<\/strong><\/figcaption><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><em>References<\/em><\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Oh Hongshik, Kim Youngho and Kim Namkyu. 2010.
