Chook Information from Nial Moores (with 이건희 on April Twenty ninth-Could third).
One other two weeks of survey of the ROK’s prime migrant hotspot. In complete, 189 species have been logged, all of which besides Eurasian Curlew (19 seen heading north on April twenty fifth) had been recorded in latest springs on this island. All every day checklists are posted on eBird.
On present information, the island guidelines now stands at 384 (with the most recent addition a single Black Redstart posted on April eleventh on Fb by Park Cheong-Un). Is there some other website or assortment of web sites with a better variety of species?
In the course of the current survey, the species complete was fairly lower than e.g., the 195 species recorded between April twenty fifth and Could 9th in 2014 ; and didn’t embrace any large-scale actions on the dimensions of e.g., late April 2020. This was in all probability largely as a result of the climate was lower than cooperative for exciting large-scale actions, with northerly winds on a number of dates and solely two or three days with any west within the wind.
Most days of fieldwork have been carried out on foot, supported by the island bus, however three pleasant days have been additionally spent travelling round by automotive with Justin Lee (이건희) – together with on Could 1st once we logged 134 species (on this case simply eight species brief of the present all-on-foot 24-hour document for the island).
There have been fortunately superb / island excessive counts of Garganey, Temminck’s Stint, and Chinese language Grosbeak (all three species apparently recovering in quantity this decade after maybe a number of many years of decline nationwide) together with in all probability a nationwide excessive depend of Swinhoe’s White-eye. Observations additionally included single Saker Falcon (ID presumed solely), Black-winged Kite and Frequent Swift, with one Giant Hawk-Cuckoo additionally heard.
Far much less optimistic was the invention of a number of traps set to catch wild birds in Jinchon (not the primary time right here…), and persevering with habitat loss, with persevering with disregard for biodiversity as all through a lot of the nation. Along with frantic infilling of what was the tidal flat and bulldozing for brand spanking new roads (together with within the far southwest), there’s a proposed new airport. This plan appears to be progressing steadily behind the scenes with evaluation bids being sought (with the main target foolishly on utilizing monitoring tech. on just a few high-profile species, ignoring the excessive migration turnover) and building doubtless from 2025. If it proceeds, this may doubtless embrace the lack of the Harrier fields and any peace and quiet in Sagot village; and can after all embrace a excessive risk of chicken strike in sure climate circumstances.
Just a few highlights / species of observe observe:
