Another shot from Gomantang caves. you find 3 swiftlets here- the other two being edible-nest and black-nest swiftlets. Mossy-nest builds a nest
with vegetable matter with little nest cement. Edible-nest constructs an all white nest of nest cement while Black-nest uses nest cement containing many impurities.
There are lots of little blue flycatchers in Malaysia. You need to check them all carefully. This bird is found in the northern mountain ranges of Sabah - a province of Malaysia though on the island of Borneo
