Two clips from Wenatchee, WA and ID help, please

["walunit" walunit]

Here are a couple of soundscapes recorded south of Wenatchee, WA on the way=
 up to the "Twin Peaks" hike.

Please scroll in to 5:58. I recorded for perhaps an hour and only heard thi=
s vocalization once. Any idea who this is? http://www.mikewallmusic.com/mus=
ic/t135_1.mp3

And here is another clip: http://www.mikewallmusic.com/music/t133_1.mp3

Please pardon the wildly inconsistent levels in the two clips.
