“Toucan,” erupted from the person on my right. In the canopy, two large birds with bright colors were mainly silhouetted against the sky, but some yellow, red, and white showed. The long bill was enough to confirm that two toucans had arrived in the Pantanal.
This was my last day in Brazil, and I’d seen Toco Toucans fly over two or three times but never had a decent look. Yesterday, a pair at Rio Claro flew across the Rio Sararé just as the sun broke the horizon. The sky and low light silhouetted their bodies. That long thick bill was unmistakable. Unfortunately, my camera didn’t focus fast enough in that nonexistent light.
The bill on a toucan is a thing of wonder. In this species, it is about a third the length of the bird but weighs very little. With strong, finely tuned muscles in their necks, these birds can use it like a fine tweezer. The bill is strong and tough. The outer layer is a series of overlapping keratin tiles that are fused – like armor plating. The interior is like foam and is made of bony fibers and drum-like membranes to form a strong ridge and brace structure – a three-dimensional lattice. The middle is hollow. The bill is a marvel of engineering, and a person who could design something like this would be considered a genius. The overall configuration gives a high degree of strength for minimal weight—evolution at its most remarkable.
The pair hopped down to where both were visible. This Pantanal lodge had put fruits, nuts, and seeds out at first light this morning, and a plethora of doves, finches, guans, chachalacas, and others had come to feed for the last 90 minutes. Toco Toucans are splendid birds, bigger than I’d expected. They are the largest toucan species. Their white bib, black body, red under-tail coverts, and distinctive red-orange bill make them pop on a tree branch. Females apparently average a little smaller, but there was no way to tell that difference in the wild.
One glided down to a horizontal log attached to two fence posts. This species is primarily frugivores, but they will take bird eggs, nestlings, small birds, lizards, and insects. They can hang upside down and use that long bill to snip fruit from twigs or probe deep into holes. Earlier, a person had spread bananas and mangos across the back of the branch and dropped small pellet-looking stuff on the feeder. Paulo, our Brazilian guide, had said the small fruit-like nuggets were items the toucans particularly liked.
The second one flew to the other end of this natural-looking feeder. It stood staring at us. Maybe fifteen people congregated behind a small fence watching the feeders. We all had homed in on this unique bird. The second one reached down, picking up a small quarter-inch pellet from behind the branch. It seemed to roll it in the tip of that foot-long bill much like a jeweler might role a diamond between her index finger and thumb. It then cocked its head slightly, flipped the nugget up, opening its mouth as the morsel flew to the throat; its foot-long tongue showed for a second as it closed its bill, to then twist a stare right into my eyes as if to say, “What’d you expect?”
