Picking up on Trilieigh's post,

A walk through Woodland Park today revealed 3-4 Chipping Sparrows chipping alongside Juncos...a good comparison...the sparrows a bit lower and glottal sounding...great views of one of the sparrows...

As well as a Warbling Vireo...

I recommend focusing on the south edge as well as the north "funnel" of Woodland Park...underrated birding IMO esp in migration - tends to be a small local attactor...
