As per Janet Partlow's post:

"I never heard of a warbler that nectared, but considering that these birds
spend much of their lives in subtropical climates, I suppose it shouldn't
surprise me. Has anyone else ever heard of or seen anything like this?"

I once saw a Yellow-rumped 'Myrtle' warbler feeding at a hummingbird feeder
in central Saskatchewan. Typically, the feeder hosted Ruby-throated
Hummingbirds.
