Media notes
NOTES: BNA: To me, sounds most like "queeeeeer"; could be Call "Tzeeeeeerrhh". mf [This represents almost exclusively the Compound Vocalization (CdV) of Smith (1966. Communication and relationships in the genus Tyrannus. Publ. Nuttall Ornith. Cl. 6), or the or "Tzeeeeerrhh" Call of BNA. There is, however, one Locomotory Hesitation Vocalization (LHV) at the end of the recording (2:01-2:03; e.g., Figure 5:5b of Smith (1966)). Quality changed from 1-2 to 2 - CAM - 22 December 2004].
