FLEDGLING BONUS PHOTO
Hutton’s Vireo.
Our biggest clue here is the fact that Ruby-crowned Kinglets do not breed in Northern California, leaving a very high likelihood this could only be a Hutton’s Vireo fledgling. We indeed observed this adorable little one being fed by an adult Hutton’s Vireo.
It was awesome.
