At 4:24:49, do hear the whistle call of the white-crowned sparrow?  He may be back for the winter, but does not show in the video, just sings in the background.

the male brown-headed cowbird sings his distinctive gurgling call at 3:54:34.  Listen carefully how it sounds like:  two gurgle sounds followed by a soft ringing sound.
