NOTES: MALE GAVE BUZZING CALL AS HE DIVE-BOMBED ANOTHER BIRD - SOMETIMES ANOTHER RUFOUS HUMMINGBIRD AND SOMETIMES A TRAILL'S FLYCATCHER -AS IT SAT ON A BRANCH IN THE MALE'S TERRITORY. THERE WERE ABOUT 6 BIRDS IN THE IMMEDIATE AREA (5 ACRES) DOING THE SAME THING. THE 2ND AND 3RD SEQUENCES (LAST 2) ARE GIVEN IN RESPONSE TO A TRAILL'S FLYCATCHER SITTING AND SINGING ON AN EXPOSED BRANCH OF ONE OF THE WILLOWS. THE 4 SHORT BUZZES ARE GIVEN AT THE CLIMAX AS THE HUMMER SWOOPS TO THE LOWEST POINT IN HIS DIVE. A STEADY BUZZ IS GIVEN AS HE COMES DOWN, ONLY WINGNOISE AS HE FLIES UP. WILLOW BORDERED SMALL STREAM RUNNING THROUGH WET FIELD.
[This recording contains two dives (0:085, 0:175), each signified by a sound comparable to the "Dive Display Noise" described in BNA account for Selasphorus sasin (see Figure 3D in that account) or as rip-saw-like "dit-dit-dit-deeeer" in account for this species. There is also some soft buzzing produced by the wings of the flying bird. Quality changed from 3 to 2, 2-3 (the signal is good for first dive, but weak for the rest of the cut) - CAM - 2 May 2005]
