Subject: [obol] What makes a hummingbird back down?
A hornet on the feeder.

I have seen Rufous and Anna's hassle each other and birds of all sizes,
including Red-tailed Hawk, but I never saw one flee anything except another
hummingbird until the hornets started gleaning sugar from the feeder
openings. They drive the little blighters right off. Everyone has their
limits.
