Media notes
The diagnostic "tu tu" call can be heard between 1.77 - 2.17 sec, of this recording. Interestingly, the bird was extremely agitated by the "griseus" ssp.voice, and completely indifferent to the call of "caurinus", based on the voices of the flocks of the above subspecies recorded in the "Sibley Birds" app.
