While enjoying the coastal waters of the Yucatán Peninsula you will likely share the beach with brown pelicans. This consummate fisherman has a wingspan of over six feet which lets it soar up to 80 feet above the Caribbean Sea. When it spots dinner, this seabird plunges straight down and scoops up in its foot-long bill as much as 2.5 gallons of water along with its catch. It eats up to four pounds a day or about half its body weight … sort of like vacationers at the hotel buffet.
