Cedar waxwings, with both seee and bzeee calls, but there will be no songs from this songless songbird. Eventually we hear intense seee calls that typically precede flight (beginning about 0:56).

And off they fly, flapping wings at 16 beats/second, much slower than the hummingbird who zips by (at 1:09) whirring its tiny wings at the rate of 59 beats/second.


Pacific-slope flycatcher, house wren, American Robin, orange-crowned warbler, Swainson's thrush, spotted towhee, lazuli bunting, whir of hummingbird wings (probably rufous hummingbird).
