Tiago Gunderson is the only son of Blu and Jewel, and one of the three tritagonists of Rio 2. He is the youngest child of Blu and Jewel's chicks, and has two older sisters named Bia and Carla. He is voiced by Pierce Gagnon in Rio 2.
Although not named at the time, Tiago and his sisters are seen at the end of the film, flying, singing, and dancing with their parents. The three chicks also sing a line during the song "Real in Rio".
Tiago is first seen helping Carla and Bia prepare fireworks at New Year's Eve, the three having tied their babysitter Tiny to a firework. He says that the show is going to be awesome. After Carla details her "vision" for the fireworks(which are colors), the impatient Tiago grabs the match from Bia and lights it after he shares his own "vision" (which are explosions). Before Tiago can light the fireworks, he is stopped by Blu and Jewel, who take away the match. He nods in agreement when Carla claims Blu always says "no". When Blu protests that he doesn't always say "no", Tiago says that he is "in denial". As the fireworks go off with Blu attached to one, Tiago flies up to the Christ the Redeemer statue with his mother and sisters. As Blu falls onto the statue beside them, Tiago grumbles that Blu always "gets to have all the fun," but then watches the fireworks in awe along with his siblings.
At breakfast, Tiago steals the blueberries intended for the pancakes, kicking them at Blu. Blu accidentally sends a pancake flying, and Tiago tries to catch it, only to be squashed against the wall. He greets his mother as she stares at them all, clearly annoyed. Jewel tells Blu that she wants to show the kids how to open the Brazil nut she found in the rainforest, but Tiago further annoys Jewel when he opens a can of Brazil nuts, claiming that their father "already showed us!". After the news announces the sighting of a wild Spix's macaw, Jewel suggests a trip to the Amazon. When Blu hesitantly agrees, Tiago is ecstatic, but then he asks what the Amazon is.
Tiago hurries Blu as they prepare to leave for the Amazon, eager to go. He takes Blu's Swiss army knife, who quickly takes it away. When Bia shows Blu a pop-up snake from her book, Tiago takes it, interested, but Bia takes it back, annoyed. Tiago brings some goggles to the Amazon, and wears them every time he flies. Tiago enjoys the journey, riding on a Rhea (urging it to go faster), and sometimes annoying his family.
On the boat they ride on for the final portion of their journey, Tiago and the others sleep. Nigel is about to kill Blu, but the boat horn then goes off when Charlie hits the switch by accident, waking everyone and foiling Nigel's plan. Nigel makes a hasty getaway, not getting caught as Jewel scolds Tiago, thinking it was him. Tiago protests his innocence, but no one believes him.
When they arrive in the Amazon, Tiago laughs when Bia takes notices of a larva about to enter the pupa stage (thinking she said "poop"). He climbs over her to get a better look, leading her to chase him. Jewel goes after them, hoping to catch them before they get lost. When the Spix's Macaw Tribe is found, Tiago looks on with awe and wonder. As Eduardo is revealed to be his grandfather, Tiago is enthusiastic and curious. He hugs Eduardo along with his sisters, calling him "pop-pop."
When Mimi tries to hug them, Tiago, Bia and Carla flee, terrified. Tiago dances with his newly found family during "Beautiful Creatures," painting his face with red. Later, in Roberto's nest, Tiago tries to bag the biggest room, but is denied it when his sisters attempt to claim it. He is then distracted by the birdbath, jumping into it. He then farts, adding, "Jacuzzi." Later, Jewel sings him and his sisters to sleep, but when she finishes, Tiago begs her to sing it again. Jewel gently declines, kissing her son on the forehead, and Tiago immediately falls asleep.
The next day, Tiago, Bia, and some other chicks scare Blu awake with a spider. As the day progresses, Roberto takes him water-skiing and teaches him how to fly backwards. Tiago calls him "Uncle Beto," and Roberto nicknames him "T-bird." At the soccer match, Tiago cheers on Roberto and Blu enthusiastically, jumping up and down and shouting. When Blu scores for the wrong team by accident, Tiago looks saddened and disappointed, flying away with the tribe, but he soon forgives his father.
During the battle with the loggers, Tiago and Bia drive a tree harvester away from the trees, Tiago using it to pick up one of the loggers. Tiago then uses the Adventurer's Knife to help break the engine of another tree harvester, and high-fives Blu when the deed is done, saying that they're "a great team." When the loggers retreat, Tiago hugs his sisters. When Nigel later tries to attack Blu, Blu pulls Tiago and Bia close to defend them, but Gabi drags Nigel away.
Afterwards, Tiago joins in the Carnival celebrations, happy in his new home.
Tiago is a happy-go-lucky, brave, free-loving, mischievous, very agile chick, who loves going on adventures. A born troublemaker, Tiago is adventurous and free-spirited like Jewel while at the same time he's a natural at utilizing human objects and enjoys them like Blu. He appears to have little manners, unlike his sisters, as shown when he burps after drinking soda, when he takes Bia's book, when he burps after drinking soda, and when he farts while relaxing in a bird-sized jacuzzi in Roberto's nest.
Tiago is the youngest of the kids by three minutes, and the only male. If something needs to be blown up or destroyed, he is the one to go to. Always up for adventure, Tiago quickly becomes right at home exploring the wild. He is extremely mischievous, scaring his father awake with a spider, and often irritating his sisters by stealing their possessions, shown when he twice steals Bia's book, and once seen taking Carla's MP3. He also tends to interrupt his sisters, as shown in the first teaser trailer, the New Year's countdown video, and the "Beautiful Creatures" video where his sisters are dancing together and he comes in between them.
Tiago is a skinny young chick who looks exactly like Blu, also having his "hair" style, but unlike his sisters he has more hair feathers that stand up, like Jewel. He also has downy feathers that stick up on the back of his neck and on his chest. He has dark blue feathers, lighter blue facial markings, light grey talons, dark grey beak, and brown eyes that are the same hazel-brown color as his father and sister's. He has the second largest wings, despite being the youngest of the brood. Being the youngest, he is also the smallest and shortest of the brood.
Tiago loves his father a lot and enjoys having fun with him. During breakfast, he kicks blueberries over to him, soccer-style and on the way to the Amazon, Tiago is seen sleeping on his father's back while flying at night. He also enjoys playing pranks on him, like dangling a spider over his face. He is seen cheering for Blu at the Pit of Doom, and cringing when he gets hit in the head with the ball. The two make a great team as Blu trusted Tiago to use his All-in-one Adventurer's Knife to open a panel on a bulldozer when the loggers attacked.
Tiago loves his mother very much. After she sings the kids her lullaby, he asks her to sing it again. Jewel declines, but gives him a goodnight kiss on the forehead. She is also seen throwing him some açaí berries, which he catches mid-air and juggles before Roberto steals them.
Tiago loves and also seems to enjoy annoying his sister, taking her books without permission, and laughing when she says "pupa" (thinking she said "poop"). But they work well together during the battle against the loggers, driving a tree harvester away from the trees. She also enjoys his pranks sometimes, giggling as he lowered a spider onto Blu while he slept. On the way to the Amazon she was also seen snuggled up to him when they slept on their father's back while flying at night.
During their attempt to set off some fireworks, Tiago shows little patience for Carla's "vision", preferring to simply set them off and watch the explosions. They briefly argue about who gets the biggest room in Roberto's nest. Nonetheless, they seem to enjoy each other's company.
Tiago enjoys being with his grandfather, calling him "pop-pop", and dancing happily with him.
Tiago, along with his sisters, was initially frightened of Mimi as she rushed to hug them for the first time. However, they later love her, dancing with her, and watching the game in the Pit of Doom with her.
Tiago likes and looks up to Roberto, calling him "Uncle Beto". He has fun surfing on lilypads with him, learning how to fly backwards, and joining in his trademark call. He also cheers for him at the Pit of Doom.
Tiago isn't seen interacting with Linda during Rio 2, but an image of the chicks with her and Tulio (shown during a news report) shows him gleefully nuzzling against her cheek, showing he likes her quite a bit.
Though it is not shown directly during the movies, Tiago has a close relationship with Rafael, who he regards as an uncle. In Rio 2, Tiago and his siblings are left in Rafael's care by Blu and Jewel, until Rafael passes them over to Luiz. The Rio: Snakes Alive! novel is the first time Tiago and his siblings are seen addressing Rafael as "uncle" while they run to greet him.
Though it is not shown directly during the movies, Tiago also has a close relationship with Nico and Pedro, also referring to them as "uncles". In the Rio: Snakes Alive! novel, the first time they are seen interacting, Nico and Pedro try to cheer up Tiago and his siblings as they are told they will be babysat by trying to teach them to dance, which does not interest Tiago as much as the adventure his parents went on.
As with Nico, though it is not shown, Tiago also has a close relationship with his "Uncle" Pedro. Pedro tries to cheer up the kids in the Snakes Alive! novel by assuring them that they "are the party," but his and Nico's joint attempts simply bore the kids.
Tiago is only referenced to interact with Luiz a few times. When Rafael decides to go to the New Year's Eve party, Rafael leaves Tiago and his siblings with Luiz, who then passes them on to Tiny. In the Rio: Snakes Alive! novel, Tiago and his family are all hugged tightly by Luiz (who calls them "little munchies") when they visit him in Rio.
