I spent night at location, getting up at 4:45am. Sun hit valley at 7:10 and hummer activity became greater. There were some Rufous around, but more Calliopes which sat on little twigs in the oaks. At times one would fly high in the air, and do a power dive, but no vocalization or humming. Later, two Calliopes met and buzzed together with faint vocalization. I made a greatly amplified copy with vocalization portion put through a 1.5KHz hi-pass filter, and this gave a good representation.

[Although one can clearly hear the humming of the wings (0:13-0:17, 0:26-0:27, 0:36-0:39), I am not certain that the bird(s) ever called here, but the thin, descending "seeee" at 0:19 may have been given by this species. There appear to be "cryptic" stop-starts at 0:225, 0:235. Times all based on beginning of recording as measured from species-reel. Quality unchanged (3) - CAM - 2 May 2005]
