Listening to a Continent Sing

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.

Background

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