It looks more like an Iduna to me - maybe Sykes's on habitat?

yes syke's are there too

But the sound doesn't belong to the warbler, does it? Sounds more like a Purple Sunbird or so...

Sound is atleast of a Purple Sunbird. Pics are of a warbler, I can't make wether its Iduna or Phylloscopus or any other. If Iduna is there, it's a Sykes - too flat for Booted.
