Hi Josh,

A small proportion of juncoes locally sing a two part trilled song, with the parts at a somewhat different pitch/pace. The halves come in quick succession. The Sibley app has one song labeled "odd two-parted buzzy songs - California " that you might want to listen to. And this would typically be delivered from atop a tree.

Good birding by ear,
Bob Sundstrom
