My vote goes to the Tyrant Flycatchers as just about the nicest birds anyone could hope to meet. Standing in their presence provides them with a perfect excuse to fly close and perch on a nearby tree.

Many species regularly frequent residential areas and consequently do not spook easily in the presence of humans. Don't expect them around the feeder because they're mostly insectivores.

Experience tells me they tend to act a bit...
