1582. Nico

Nico is a miniature yellow canary, and as Pedro's best friend who also befriends Blu when he comes to Rio. He wears a green bottlecap as a hat.

Nico and Pedro met Blu while the vehicle that Tulio, Linda and Blu were riding, stopped. They talked to him and even thought that the SPF on Blu's beak was "Pigeon Doodoo". They told Blu that they would help him get out of there which leads to Pedro repeatedly hitting his cage but fails to break it. Blu explains and tells them that he's safe and so, they said goodbye as they flew away.
They meet again in a marketplace where Rafael took them to see Luiz but they said that he left. As they meet up, he teases Blu with Jewel which made them take the two macaws to a bird's samba club. He starts to sing "Hot Wings (I wanna party)" together with Pedro. Suddenly, they were attacked by the marmosets and all of them fight the monkeys together. He then sees that Kipo, a Roseate Spoonbill, helps Blu and Jewel escape though some monkeys caught them which leads them having a hard time to escape. He gets his bottlecap and aims it to the first monkey. Fortunately, they escaped by riding a tram and sets off to Luiz's garage.
Meanwhile, Rafael decided to "set the mood" for Blu to confess to Jewel. Nico starts to sing "Fly Love" so he could set the mood while Pedro plays a set of strings as a guitar and Rafael falling off cherry leaves from the trees. Blu blows the moment up by saying the wrong things and being choked by swallowing a leaf.
The group meets with Luiz, a bulldog, and he tries to break the chain by using the groove cutter. Everything goes wrong but in the end, they were released with Luiz' drool. Nico flies with Jewel together with Rafael and Pedro leaving Blu depressed. Blu tried to tell how he truly feels for Jewel instead, he says that he hate samba and made Nico cry. Afterwards, they part ways but Rafael told them to follow Jewel and so they did. All of a sudden, she was captured by Nigel while they go back to Blu and Rafael telling them what happened. They go to the Carnivale to look for her and luckily, they saw her in a weird chicken float. Nigel catches them all including him.
While in the plane, Blu managed to escape and helped the others too. Blu opens the door which leads them to escape and have freedom.

1501. Jewel

"The gem of the forest, but don't let those long batting eyelashes and silky blue feathers fool you. She's one sassy chick and the opposite of Blu. She loves to fly and cherishes her freedom, and would never look into a cage let alone step into one. When she find herself stuck with a domesticated "pet", she learns that being grounded may not be so bad after all."

Jewel is initially fiercely independent, with a love of flying free, she is selfish, she has a funky attitude, and does not care about anything but escaping and flying. She is very mistrustful of humans (badly scratching one of Tulio's assistants) and doesn't think much of the "pet" bird Blu. After their duet at the samba club however, she warms up to Blu considerably. When he jumps out of the poacher's plane after her, she is touched to the point of kissing him passionately. With encouragement from Blu, she seems to overcome her distrust of humans, allowing Tulio to tend to her injury.

1491. Mauro

Mauro is the head of a tribe of mischievous common marmosets who steal from tourists and are experts in Capoeira. He and his gang are forced to work for Nigel and obey the least of his orders.

After a busy day stealing from tourist, Mauro and his minions are approached by Nigel, who coerces them (By dropping Mauro from a great height) into finding Blu and Jewel. Mauro's forces find the birds, and engage in battle with them and their bird friends, losing both the fight and their quarry. A dazed Mauro is later manhandled by Nigel for failing. After Nigel is reduced to a featherless mess, Mauro gains some measure of revenge by taking a picture of the humiliated cockatoo.

1488. Nigel

A conniving cockatoo, Nigel is not a pretty bird... but he used to be. Once a popular telenova star, he was replaced by a younger and more colorful bird. Now he has it out for all birds for beauty. Today, you'll find Nigel putting his jealousy and rage to find in his new role as "evil henchbird" to the smugglers.

Nigel is first seen as a "patient" at Tulio Monteiro's aviary. However, his sickliness is quickly revealed to be a front for him to let Fernando in so he can steal Blu and Jewel and bring them to Marcel. When Jewel tries to escape, Nigel pins her down and returns her to Marcel. After Blu and Jewel are locked up, Nigel comes to them, explaining his motivations with the song Pretty Bird. Later, Nigel hears them trying to escape, and tries to stop them. The chase leads into the slums of Rio, where Nigel collides with an electrical transformers. The next day, Nigel is sent by Marcel to retrieve Blu and Jewel, extorting the help of Mauro and his underlings to do so. After they fail to capture their quarry, Nigel goes after them himself, capturing Jewel and using her as bait to draw in Blu.After the captives are loaded into the smugglers plane, they manage to get out of their cages. Nigel is sent to stop them, pinning Blu and injuring Jewel's wing. However, Blu manages to hook a fire extinguisher to Nigel's leg and set it off, sending him flying out of the plane and into the propeller.
Afterwards, Nigel is shown to have survived, but lost most of his feathers in the process. Mauro then takes a picture of Nigel, to his humiliation.
