Description of the Bird

I guess this could be a 1st for Crowley County, as the CBRC is asking for documentation.  Two small vireos, bright yellow underparts, black line through eyes, and vireo shaped bill.  See photos.

Similar Species Discussion

The bright yellow underparts and black through eyes are wrong for Warbling Vireo.  The bill shape is wrong for warblers.
