That is amazing! Beautiful places in Brazil, when I lived in Rio De Janeiro, I did a little bit of fishing right off of Macumba beach in Recreio. Not sure what type of fish we were going after, (no bites) but we saw a few Cariocas pull out some nice looking silver fish, tried to communicate... no luck.
It's amazing how some of those birds dive in from way high up and pull out some fairly large fish on their way back out of the sea.
