“Some birds (perhaps most) have the ability to raise crest feathers. Among kingfishers the Banded Kingfisher (Lacedo pulchella) is well known for this behaviour.
“I had not previously documented this in White-throated Kingfishers (Halcyon smyrnensis). Their resting behaviour is better seen as a head bobbing, up and down. I saw this White-throated Kingfisher frequently raising its crest feathers (above, below).
“This is not as apparent as in some other birds. The reason for this behaviour is uncertain. It could be due to excitement or a display of sorts.
“Although I was watching closely and could be the cause of the behaviour, it however largely had its back to me, and very soon after caught a nice fish (above).
“I suspect it is a common activity, but missed. I have GIF file of the activity but it is too large to upload. Images converted into a video file here but they do not loop, so replay to see activity well:”
