Hi Sze, on 30May(Sat), I went to Mui Wo for birdwatching and found out that there are many nests made by barn swallows too. There are at least 10 nests around Mui Wo centre (the 4 buildings around 銀運路, there is a Wellcome). From my rough estimation, 7 out of 10 nests were occupied but so far I didn't see any chicks. Has HKBWS had some records for those nests already?
