Tropical Kingbird

The tail gives it mostly away. http://www.birds.cornell.edu/crows/kingbirdsX.htm

We have Tropical Kingbirds in our area. They are so bigger then our Western.

I love how in the video he tracks a insect as it goes by. Nice spotting!

Nice portrait of this bird!

I like the video, Ismael, looks like a young, Tropical Kingbird Tyrannus melancholicus. http://www.projectnoah.org/spottings/25826036

It's extremely hard to tell this guy apart from the Couch's Kingbird, but the Couch's has a much smaller range that very rarely includes Costa Rica, so it made it easier to know which one it was :)
