[rec.birds] Help me identify two birds by their distinctive songs?

I've listened to everything on the records that go with Peterson's Western
Birds book except the waterfowl (which I think you'll agree is an unlikely
listen), and I still can't find these two... maybe someone has heard them.
Or maybe they're somebody's escaped pets. Anyway:

1) Some kind of warble followed by six notes: D ^ E ^ G ... v C ^ E ^ G...
sometimes given twice, with a rhythm like "ball-bearing, ball-bearing" where
ball and bearing take up the same amount of time. The ^ and v indicate
direction of pitch movement. The average pitch is about that of a robin's
evening song. I heard it while walking through some park blocks here in
Portland, Oregon.

2) A rather wild warble finishing by bouncing back and forth several times
between two notes an octave apart, about three notes to the second. The
upper note was a bit higher than 1). Part of the bouncing effect could have
been an echo - I heard this one in a high canyon adjoining the Columbia
River Gorge at about 2500 ft. Now don't tell me it was a mutated hermit
thrush that flew over from Hanford. :-) Seriously, any suggestions?
