Need help with Vireo id's at Phoenix and Portal (1 Viewer)

[K B Srinivas]

Hello All,
Need help with these vireo id's. Took these pictures during my recent Arizona trip in April.

1. Picture taken at Boyce Thompson Arboretum in Phoenix on April 27. Is this Plumbeous vireo?




2. This one was taken in Portal Arizona on May 2nd. Is this Cassin's vireo?



Thanks,
Srinivas.

I don't know these species, but I think I detect greenish colour in the secondaries of the second bird which Sibley says indicates Cassin's. I'm unable to judge the various colour shades for the first...
