We had a Tropical Kingbird wander up here a few weeks ago. He is mostly common to the American tropics. Some reach South Texas and South Arizona and they span to Argentina, Peru and Trinidad.
We had snow shortly after this one was found so I am not sure what he thought of that. The bird books say that a few juveniles wander north in the fall to California but not much further. He mostly sat on this wire and observed looking for insects and hawking them from his perch. Then he would fly back to a large ivy covered tree and stayed up high all the time.
He is part of the Tyrant Flycatcher family, a perching bird with bright colors. I am not sure what he found to eat at is was so cold. They commonly eat insects and some fruit and berries. Apparently they can be very aggressive protecting their nest areas. This little fellow was alone. They studied breeding Tropical Kingbirds and found some stayed together for four years which is pretty good for a bird.
This is the distant shot with the camera before cropping. Cornell is wanting to do more research on the migration of these birds and the range of the wandering Tropical Kingbirds.
