Selected Korean Birds

Tundra Bean Goose
(Anser fabalis serrirostris)

The Bean Goose is a common winter visitor to Korea. These photographs were taken in Seondu-ri, Ganghwa Island, on March 22, 2003. The middendorffi subspecies of Bean Goose also occurs, but most of them winter in the southeast.

Red-crested Pochard
(Nettia ruffina)

Red-crested Pochards are very rare visitors to Korea. These photographs were the documentation of the 6th national record. While I had seen a female at Junam reservoir in the south in January (it has wintered there for the past 2 winters), this male was much more attractive. It was in the company of Tufted Ducks (Aythya fuligula) and Common Pochards (Aythya ferina), both of which can be seen in these pictures. The Red-crested Pochard, for those not familiar with Eurasian duck species, is the one with the red bill.

(Chinese) Great Cormorant
(Phalacrocorax carbo sinensis)

While common throughout the country in the winter, Great Cormorants become rather more localized as the year progresses, although small numbers often remain on the Han River in Seoul through the summer. The sinensis subspecies differs incredibly from Nova Scotian birds (ssp. carbo?) in the white head feathers acquired in adult breeding plumage, as seen on this bird on the Han River at Oksu, Mar. 30, 2003.

Oriental White Stork
(Ciconia boyciana)

Oriental White Storks, with a world population of only about 2500 birds, are extremely rare, particularly in Korea, where only a few were present in the winter of 2003, including this incredibly cooperative bird on the edge of the town of Ganghwa. Photo taken January 25, 2003.

Saunders' Gull
(Larus saundersi)

Another globally rare species, Saunders' Gulls winter almost excusively on the Yellow Sea. This was one of over 50 of them that was present aroud the tidal flats at Seondu-ri, Ganghwa Island, on Mar. 22, 2003. My apologies for the quality of the photo.

"Mongolian" Gull
(Larus (cachinnans) mongolicus)

Common on fresh water throughout Korea, whether the Mongolian Gull is an independent species or not is currently a matter of debate. It is not difficult to separate from other white-headed gulls occurring in Korea if you know what to look for.


Adult Mongolian Gulls (photos taken in Seoul in late March). These are two different individuals.

Second-winter Mongolian Gull (same individual in both photos). Photo taken in Seoul, mid-March.

Two examples of first-winter Mongolian Gull. These birds are in 1st-winter plumage, but are moulting into 1st-summer.
Little Ringed Plover
(Charadrius dubius)

Little Ringed Plovers are common on migration, when they can occur almost anywhere -- on coastal tidal flats, on small streams, or in ricefields. They're cute little Plovers, reminiscent of the Semipalmated Plovers which occur with similar frequency in Eastern Canada. These ones were loosely accompanied by about 200 others in ricefields and along small streams around Daegok, which is between Seoul and Ilsan, in late March 2003.

Kentish Plover
(Charadrius alexandrinus dealbatus)

Kentish Plovers are fairly common on the Yellow Sea tidal flats on migration, but are apparently less common as breeding birds. I was quite happy to find a pair breeding, albeit in an active gravel pit, along the Geum River near Kunsan, on the West coast. This is a photograph of the nest, which is lined with small shells and shell fragments. Approximately 300 metres farther up the shore, another Kentish Plover gave a distraction display, indicating a strong possibility that there were two nests in the area.

Mongolian Plover
(Charadrius mongolicus)

Mongolian Plovers, like Kentish Plovers, are common on the tidal flats along the West coast of Korea. They, however, do not remain to breed. This Mongolian Plover was with about 80 others on the Geum River estuary tidal flats near Janghang, across the river from Kunsan.

Large-billed (Jungle) Crow
(Corvus macrorhyncos)

The Large-billed Crow is fairly common, at least in the north-west of Korea. It is particularly common in the winter, when large numbers of them can be seen in mountainous areas, the species' preferred habitat. There seems to be a significant southward dispersion from more northerly breeding areas into Korea between December and March. More similar to Northern Raven than to any other North American corvid in terms of their build and size, their calls are also quite Raven-like. This photograph of a Large-billed Crow and one of the three Eurasian Magpies that was harassing it was taken in Namsan Park, central Seoul, on March 18, 2002.

Long-tailed Tit
(Aegithalos caudatus)

The photograph to the right is of a white-headed Long-tailed Tit, which is quite a rare winter visitor to Korea; the photograph on the left, below is of the same individual, which was near Eungbong station on the Han River in Seoul on March 2, 2003. A number of white-headed birds were reported in Korea in the winter of 2002-03, indicating that this may have been a bit of an invasion year for them. I believe that the birds pictured here is probably of the subspecies japonicus, as the tertials were pink. The tertials of the caudatus subspecies are apparently white. The bird below, on the right, is a typical example of the resident Korean subspecies, A. c. magnus. Note the black lines visible on the head. The calls given by the two varieties are also different, and the white-headed bird shown here was located by its more abrupt call, which does not trail off at the end as the call of magnus does.

Marsh Tit
(Parus palustris)

Marsh Tits are one of the four common tits found in Korea (the other three are Great, Coal, and Varied). Contrary to what their name would seem to indicate, they are often found away from wet areas. They can be found almost anywhere where there is a suitable amount of cover -- in forest, brush, or reedbeds.

Chinese Nuthatch
(Sitta villosa)

These photographs, of a male Chinese Nuthatch found on Ganghwa Island on April 19, 2002, represent only the second time, to my knowledge, that the species has been photographed in Korea. There were two males present in the same area on that day, distinguished by slight sifferences in their colour pattern (it is possible that one was a first-year male and the other was an adult). While generally quite rare, the winter of 2002-03 featured an incredible invasion of them, and possibly up to 8 (including these two) were reported in the northeast of Korea. A cute little bird, similar in many ways to the North American Red-breasted Nuthatch, it is coloured slightly differently, and the calls are quite different from those of the latter species.

Black Woodpecker
(Dryocopus martius)

A rare bird in Korea, as in much of its range, the Black Woodpecker is an amazing bird. It seems to be somewhat fussier in terms of its habitat preference than the Pileated Woodpecker (Dryocopus pileatus) of North America, being found mainly in areas with intact tracts of old growth. I have only seen them in a couple of areas to the north of Seoul. Their flight and feeding behaviour is similar to that of the Pileated. They feed on the insect larvae and/or ants found in dying coniferous trees by flaking off large chunks of bark and drilling into the underlying wood with their powerful, ivory-coloured bill. Like all woodpeckers, they have a specially designed, extra-long tongue to reach deep into the trees retrieve the insects which they feed on. I found this Black Woodpecker feeding in a pine tree in Gwangneung, to the north of Seoul, on January 31, 2003.

Japanese Wagtail
(Motacilla japonica)

Japanese Wagtails are rare in Korea, and are generally limited to the Southeast. This bird was part of a small flock on a stream in Gyeongju, which were the only ones I've seen. Their beautiful black and white pattern makes them very distinctive.

Naumann's (Dusky) Thrush
(Turdus naumanni)

Naumann's Thrush is a fairly common winter bird in Korea. The two subspecies, Naumman's Thursh (T. n. naumanni) and Dusky Thrush (T. n. eunomus) do interbreed, and intermediates are seen regularly in flocks of this species. Naumann's Thrush (above, left) is characterised by reddish-scaled underparts, plain wings, and a red tail and eyebrow. It tends to prefer wooded areas. Dusky Thrush (below, left), on the other hand, has white underparts, with a scaly black band across the breast, usually with some scattered black scaling, and a white eyebrow. The wings are red, and the tail is plain. It is seen more often in open areas, such as ricefields. These pictures, however, clearly show that they can both occur in the other's preferred habitat, as the Naumann's is in a ricefield and the Dusky is in a scrubby area of a city park in Seoul. Intermediates can show almost any combination of characteristics.

Pale Thrush
(Turdus pallidus)

Pale Thrush is a common bird in Korea, particularly on migration. It tends to be rather skulky, though, and for that reason it is often difficult to find. Most often, it is either flushed, or found by following the sound of its digging in the leaves. That is how this one was located, at Namsan park in central Seoul in March 2003.

White's (Scaly) Thrush
(Zoothera dauma)

White's Thrush is a common migrant and breeding bird in Korea. Like Pale Thrush, however, it can be difficult to find, although large flocks sometimes occur, such as a flock of 30+ seen one day in October 2002 at Namsan Park in Seoul. In late April and early May, pairs can be heard singing their slow-paced, high-pitched duets in almost any forest of suitable size. Striking in flight because of their strong white wingstripe, they are a very unique bird. This White's Thrush was part of a flock of four seen at Namsan Park in Seoul, in early April 2003.

Blue Rock Thrush
(Monticola solitarius)

Blue Rock Thrushes occur regularly along the coast in Korea where there are large rock outcrops, like the ones where this male was seen singing at Ahnmyeondo, south of Seosan.

Red-flanked Bluetail
(Tarsiger cyanurus)

A common migrant and rare wintering bird in Korea, Red-flanked Bluetails are a beautiful little chat. While females such as this one are less flashy than their gorgeous male counterparts, they are still a nice bird to see. While there were a few males present at the same time as this female, none of them were willing to pose quite as well. Photo taken at Namsan Park in central Seoul in early April 2003.

Common Reed Bunting
(Emberiza schoeniclus)

A bird that is only found by visiting reedbeds, the Common Reed Bunting is an uncommon winter visitor in Korea. It is more common in the southwest, although this one, which was part of a flock of over 150 reed buntings, of 3 species, was at Ganghwa Island in the Northeast on March 22, 2003. Many of the birds in that flock (this one is an example) were feeding in the dirt beside the reedbeds, rather than in the reeds themselves. I hadn't seen this behaviour in the winter, but it's possible that with the warmer temperatures and the thawing ground, there was more food to be found there.

Pallas' Rosefinch
(Carpodacus roseus)

An uncommon winter visitor to the northern parts of Korea, there were over 40 individuals present at Suraksan, in the northeastern part of Seoul, on January 11th, 2003, when I took these pictures. Unfortunately the beautifully patterned, hot pink adult males were somewhat less cooperative with the camera. The bird to the left is an immature male, the birds below are presumed to be a female (left) and an immature female (right).
