There is no doubt now. Its a real observation and have material to explore.
Think in that line only.
Hope you may arrange an oscilloscope to compare the both call(in open beak sounds & in close beak throat vibrations).
If you could provide that comparative ocillograph then only some language can be prescribe.
really observed this bird singing
ACTUALLY THEY OPEN THE BEAKS WHILE CALLING. BUT IT IS OBVIOUS THAT THROAT MOVEMENTS ARE FACTORS.
YOU CAN RECORD THE SOUND AND COMPARE IT WITH THE OPEN BEAK CALLS IN OSCILLOSCOPE AND CAN PROCEED FOR A REAL OBSERVATION, AN WORTHY ONE.
definitely singing--notice the feathers on the throat--and I could hear it
Not singing but roosting
