While more analysis is required, survey focused on the Nationally Vulnerable Long-billed Plover Charadrius placidus 흰목물떼새 by a Birds Korea team along c. 77km of the three main rivers in the Biosphere Reserve found a grand total of 63 individuals, and 38-42 suspected breeding territories.
This research, supplementing once-every-three day counts of Scaly-sided Merganser along core stretches of the Imjin River by Yeoncheon Birds Korea, also covered habitats within the CCZ, and a few hours only in hill forest.
In all, we recorded 115 bird species, including at least four which we had not previously seen in the County, together with an interesting mix of tardy winter birds and early spring migrants.
In addition to very large numbers of Hawfinch and some thrush flocks, species of greatest note included:
- Swan Goose Anser cygnoides 개리. Re-assessed as Globally Endangered. One in rice-fields between Jeongok and Yeoncheon Eup on April 1st. This is the second record this year, and follows soon after three documented by Director Baek on the Imjin River.
- Common Shelduck Tadorna tadorna 혹부리오리. Very unusual in the ROK away from the coast. Two on the Imjin River at Baekhak from March 29th to April 1st at least.
- Red-breasted Merganser Mergus serrator 바다비오리. Unusual away from the coast. On 29th, a female (2cy?) was with a 2cy male Scaly-sided Merganser at Horogoru; and a separate male was seen near to Baekhak.
- Hill Pigeon Columba rupestris 낭비둘기. A total of 18 were seen on the 3rd (up to 150 were present in the area in March).
- White-naped Crane Antigone vipio 재두루미. A total of 44-48 were seen in the CCZ.
- Red-crowned Crane Grus japonensis 두루미. A lone 2cy was in the CCZ on April 3rd.
- Temminck’s Stint Calidris temminckii 흰꼬리좀도요. One was at Baekhak on March 29th. In addition to be being a very early record at the national level, this is also our first record of this scarce migrant in the Biosphere Reserve.
- Saunders’s Gull Chroicocephalus saundersi 검은머리갈매기. Extremely unusual away from the coast. One was seen flying upstream on the Imjin River on 29th. Unsurprisingly, this is the first record we know of this Globally Vulnerable species in the Biosphere Reserve.
- Cinereous Vulture Aegypius monachus 독수리. Five were still present near Yeoncheon Eup on April 1st; and one was seen on 3rd.
- Alpine Accentor Prunella collaris 바위종다리. One was seen in Godae San on April 2nd. This is our first record in the Biosphere Reserve.
