NOTES: General climate: DRY; SEMI-ARID TROPICAL WOODS. HIGH PASS FILTER. ON 10 JUNE 1979 IDENTIFIED AS TYRANNUS COUCHII BY L.I. DAVIS. ON 02 JULY 1979 IDENTIFIED AS TYRANNUS COUCHII BY L.I. DAVIS. IDENTIFIED AS T. COUCHII BY T. PARKER APR83 - GB. Sex: 1 UNKNOWN [These indeed represent the Regularly Repeated Vocalizations (RRV) of Smith (1966. Communication and relationships in the genus Tyrannus. Publ. Nuttall Ornith. Cl. 6), which presumably are comparable to the "Dawn Songs" of BNA. Each RRV is preceded by a variable number of "Tzeeeeerrhhh" Calls (or Compound Vocalizations; CdVs). Quality unchanged (2-3, due to odd hissing noise) - CAM - 22 December 2004]. Habitat: Forest.
