Wednesday's surprises

The last couple of days have brought some nice surprises at Nahanton Park. Wednesday morning wasn't as birdy as the weekend walk, but at the end of the upper garden the bird below flew up to me.

What is this bird? Surely a Magnolia Warbler? But what's with the white throat and handlebar mustache? And it didn't seem to show the flashy yellow rump and tail pattern of Magnolia. So not a Magnolia. Prairie Warbler, but a hybrid with something - Tennessee perhaps? Prairie has known hybrids with Yellow and Blue-winged Warblers, but as far as I can tell not with Tennessee.

Nearby there were these three birds: pop quiz, what are they?
