Southern California Vireo May 2021 (1 Viewer)

Hi all,
I’ve posted this Vireo to multiple sites/people, and the majority said they think it’s a weird Warbling Vireo. I’m still not convinced, though. I believe it might be a Red-eyed Vireo, and understand that from my photos it’s probably better off not calling it one. I thought I might as well post it anyway. May 2021, Orange County, California. My only two photos. Reasons I think it’s a Red-eyed is the seemingly very strong eye-line, but I’m probably wrong. Opinions appreciated.

Minor point, but the eyes aren't red. Should be some indication for red-eyed I think

Another point of note is that this individual shows a long tail which is a subordinating field mark for warbling. Red eyed typically has a shorter tail. I’m not sure that it is reliable as a primary field mark, but it could be depending on the specifics. For example, a tail this long might be diagnostic, whereas a short tail does not necessarily prove an identification of red eyed. I am unsure of the spectrum and at what point reliability of this field mark increases/ decreases.
