What's this photo's ID (of a hybrid warbler recently present at Summer Lake in south-central Oregon)?

My guess is as good as yours, though my initial thought is a form of Canada Warbler, given the trace of the necklace and eye ring typical of a classic male Canada Warbler.
Other field marks suggest Black-throated Blue, American Redstart and either Mourning or MacGillivray's.
Someone suggested the cross/intergrade appearance is most closely alligned with Junkin's Warbler, meaning it shows
field marks associated with Mourning and Kentucky.
