NOTES: calls, song fragments, chatter from unknown location in deciduous tree [This appears to represent a highly agiated combination of Regularly Repeated Vocalizations (RRV), Compound Vocalizations (CdVs; "Tzeeeeerrhhh" Calls), and Incipient Locomotory Hesitance Vocalizations (ILHVs), all of Smith (1966. Communication and relationships in the genus Tyrannus. Publ. Nuttall Ornith. Cl. 6). Though not recorded at dawn, this would probably represent the "Dawn Song," "Tzeeeeerrhh" Call, and "Kip" Call of BNA. More than one bird appears to be vocalizing, so this may represent some sort of interaction [??] Quality changed from "E" to 1-2 - CAM - 22 December 2004]. Other Behaviors: Court, Advertise. Habitat: River, Riparian.
