The Twighlight Zone

Did Suan Rot Fai late afternoon but heavily moisture-laden clouds made everything very dim well before sunset.  Kept getting fleeting glimpses of interesting-looking birds that never reappeared with the only thing nailed of any real interest being a Siberian Blue Robin tic'ing away in a dense bamboo clump and then showing briefly.  Also a couple of Asian Brown Flies seen, and a Taiga heard. One other notable record - a group of three Cattle Egrets (not so common on the patch) over at dusk.
