The Tropical Kingbird always perches in open in all kind of habitats. I saw it atop a tree or another high exposed place like a wire. It's a common widespread bird in Venezuela. Always like a king up erect watching alertly for flying insects. Sometime it sallies to ground foliage or water. It can be rather noisy. It hovers well and pursues prey in agile flight. I could easily observe this little chap, it was fearless.
