“Had an opportunity to watch Striated Swallows (Hirundo striolata badia) up close, preening with many calls (above, below). [Please note: This species is now known as Rufous-bellied Swallow (Cecropis badia), an endemic to the Thai-Malay Peninsula – see comment by Subaraj Rajathurai below.]
“Calls were predominantly the tremulous “schwirrrr” HERE and waveforms/sonograms below.
“…and a sharp “cheenk” or “tweep” HERE and waveforms/sonograms below. (see David Wells 2007).
“The video shows some of these calls but is soft.
