Black-capped and Bell's Vireos

It took me a little bit, but eventually I started hearing Black-capped Vireos.  It took a little trial and error but I eventually tracked one down.

They seemed to forage in the middle layers of some of the denser scrubby trees.  I ended up seeing a few more.

 There can't be that many passerines with bright red eyes.

And transitioning from the most boldly marked vireo to possibly the least marked, Bell's. 

It eventually came out more into the open

Hopefully I'll recognize this bird if it turns up on Floral...
