Saw this bird in Calgary, AB, Canada, Aug 19, 2019. Philadelphia? Warbling?

Warbling Vireo

I am really not sure. Assuming the yellow is not due to the light, there is way too much yellow on its underparts. Also, this individual has a more distinct face pattern than Warbling, and there is a lot of yellow on the primaries. However, if you see the throat in picture 1, it is yellow, but in picture two, it is mostly white due to lighting. If this also happens with the rest of the body, this might be a Warbling. Like in the second picture, the brightest yellow is in the flanks, not the throat. These two species show so much variation that I think it is better to wait for more opinions.

I believe that one differentiator is the dark line through the eye.  Philadelphia goes all the way to the bill while the line on a Warbling tends to get paler as it approaches the bill.  That said, it is subtle and tricky for these photos.  The first photo would suggest Warbling to me but more input is needed from those who regularly separate these species in the field.

This was taken 10 days ago , one of a family of Warbling  that I have followed all season, through mating, nesting and fledging. Just for comparison.
