I've been hearing that around our house now for several weeks. It somewhat coincided with the return of a huge flock of evening grosbeaks. We also live in a pine wooded area around 8400 ft. We have a few pairs of black headed grosbeaks with young, several western tanagers, and every woodpecker/nuthatch you'd expect here. After listening to sound samples online, the closest thing I came up with was the evening grosbeak 'type 5' sound. It doesn't have the little lilt or lift your sound sample has (which is exactly like what I've been hearing at my house) but it's close. The sounds come and go much like the flock of grosbeaks. Sometimes we'll hear it all over, then it's gone. Our evening grosbeaks do make the more traditional rasping gym teacher whistle type sound when they are on our feeders. I've spent some time trying to ID who is making this sound and am confident I will find the bird making this whistle soon and will let you know for sure who it is.
We only have a few goldfinches vist once or twice a year and they never stay more than a few days so it's definitely not them. It's a loud sound you'd expect from a grosbeak sized bird.
