White-throated Rock Thrush  
  (Monticola gularis)  
       Recorded by Peter Ericsson on 2017-10-29
Thailand, Khao Yai National Park
Comments: call.   This was recorded right before the bird leaves for breeding grounds. I haven't heard it vocalize before so it was a bit of a surprise. I assume the piping and chucking are contact calls in preparation for breeding.       Citation: Peter Ericsson, XC171513. Accessible at www.xeno-canto.org/171513.
