Having arrived at Ganghwa bus terminal, I boarded a bus to Chondungsa, where I disembarked and walked in a large loop around the southeastern part of the island. This hike took about 6.5 hours.
Conditions were clear, sunny, and hot, which generated a lot of haze over the tidal flats, making identification of distant shorebirds difficult, and resulted in a very uncomfortable sunburn. Conditions over the ponds and ricefields were ideal, however, and the following species (and numbers) were recorded:

1. Little Grebe Tachybaptus ruficollis (1)
