Toco Toucans are best known as the fruit-eating bird on Fruit Loops boxes, but there's something else in their diet that's turning heads.
The birds hail from South America and have a sharp chirp.
"They have a really beautiful red-yellow-orange bill and a shark contrast between black and white," said James Breeden, a zoo keeper.
Beneath the colorful surfaces there's a darker side. Birds like Cha Cha and Carlos eat much more than fruit loops.
"A lot of people don't know that the beak is also used for reaching down into bird nests to grab chicks, so a lot of people think that these birds are only fruit eaters. But, they also eat other bird species," said Breeden.
Over the years, their beaks have adapted in shape to what they eat; adding more space with little weight.
"One of the modifications of a Toco Toucan is to have a really hollow beak, so it would look much like a honeycomb," said Breeden.
Keepers say the lighter they are, the easier it is for them to fly away with food.
The Toco Toucans are also like woodpeckers in that they use their beaks to prepare nests for their young ones.
To promote reproduction, keepers have added man-made nest boxes to their exhibit.
To create those nest boxes, keepers grab a palm tree, cut it in half, and completely hollow it to hopefully promote some successful nesting.
"We will also put different types of material inside the log so they can both share in taking out the material to prepare them for nesting," said Breeden.
Preparations that will hopefully pay off for future generations of Toco Toucan.
Cha Cha and Carlos have not successfully breeded, but keepers say they are actively taking out pieces from the nest box as part of their courting ritual.
