"The Eastern Kingbird is highly aggressive toward nest predators and larger birds. Hawks and crows are attacked regularly. During the summer the Eastern Kingbird eats mostly flying insects and maintains a breeding territory that it defends vigorously against all other kingbirds. In the winter along the Amazon, however, it has a completely different lifestyle: it travels in flocks and eats fruit." ---- Cornell All About Birds website.

Trying to recall now but I may have used a Tamron TC 1.4x on this shot.
