Sorry, for the late report but I had to learn how to add my audio recording to my checklist.

 

For the first time in this park, I heard and then saw a Warbling Vireo.  It was about noon yesterday in the oak trees almost at the bottom of Whipsnake Trail above the creek.

 

My entire check list is at eBird Checklist - 19 Apr 2021 - Fernandez Ranch - 18
