The Kingbird is in the family of Flycatcher. Rumor has it that while amongst the quick sunsets, hobnobbing with Parrots and enjoying a cocktail with the Palm Trees, while the rest of us endure winter, a Kingbird primarily eats fruit. I don't know how true this rumor is, but I'm beginning to believe it. Phoebes, also in the family of Flycatcher, have been nesting since almost March, and they only pretend to fly south. It's possible that through the winter when insects are scarce Phoebes also eat fruits, seeds and berries.
There's no doubt when you see a Phoebe snatch a Cabbage White Butterfly from the
grasp of a Kingbird that the Kingbird could be out of practice in the finer arts
of ridding the wild cabbages, in abundance this year, of a primary pest. Mind
you The Phoebe has nestlings to feed, the Kingbird is still far too interested
in looking splendid to have yet engaged in the nightmare business of nesting.
The other thing about Phoebes is the quality of their sneakiness. Don't be
fooled by their name, or their "pity me" call, they are high end scoundrels and
there's nothing cute about them.
