Observation details
*high count; morning departure from roost counted by 10s as massive numbers of Forest Wagtails departed the mangroves and flew mostly W and NW. I counted these very carefully and the departures were in groups of up to 700-800 but mostly 20-150 at a time. The departure continued for almost an hour but most of it (more than half) was in the 6:10-6:25 window. Some photos and audio to help document this, but those obviously can’t approach the scale of this count. This represents a high count for the world in eBird, and 50 in Kaeng Krachan (is that an accurate number?) being the next highest count for Thailand. See also the roost arrival count from the previous night. eBird has only three other counts over 650, all from Sri Lanka: 900 of 22 Feb 2022 from Gampaha, 1000 on 31 Jan 2003 from Monaragala and 1716+ on 24 Mar 2022 from Gampaha. In discussions with Jay, he suspects this is a staging phenomenon which makes sense to be given a minor uptick in my Forest Wagtail encounters at Cape Promthep lately along with the coincidence in date with the other high count (24 Mar).
