Jewel

Jewel (chained to Blu) is the deuteragonist of Rio, and appears alongside Blu, trapped in the same cage that he is contained in, as she is the only other Spix's Macaw. Once she is freed, she becomes a usable Bird, but is only used in some levels in Beach Volley, the final level of Jungle Escape and a couple of Market Mayhem. She makes Bomb's pain noises. She was kidnapped by Nigel in the episode Smugglers' Den in the final level, then got freed by the Angry Birds. She is chained to Blu, and when clicked or tapped, she flies straight forward. As shown in the Rio movie, she has 3 baby macaws. Jewel also makes a cameo appearance in her Toons design in Angry Birds Rio when you use the "Call the Flock" Power-up, where she might appear with the birds.

Rio
She is a Blue Spix Macaw. She has dark feathers, a tall body that gets fat at the end, light blue feathers on her belly, a dark gray curved beak and black feet. She has two large eyes with blue irises, blue feathers that extend to the back, feathery wings, nostrils and a large blue feathery tail. She wears a flower near her head but it didn't appear in the Rio 1 episodes.

Rio 2
She is almost the same as before but her skin color is a bit brighter than in the Rio 1 episodes. The flower she wears near her head which didn't appear in the Rio 1 episodes appears in the Rio 2 episodes.

Angry Birds Rio (Rio 1)
Jewel is first seen in the first comic cutscene, worried with Blu as the Angry Birds were also captured and reached the den. However, she only makes a physical appearance in level 1-30 of Smugglers' Den, as a caged bird target with Blu. After freeing her, she will give 5000 points. She first appears playable chained with Blu in level 2-30 of Jungle Escape, where she can be used to defeat Nigel but it's recommended to launch them at the vines.

In order to use Jewel chained with Blu, the player must launch her and wait until she gains flight, she will drag Blu with her when she speeds up. In level 4-30, after Jewel is captured, she cannot be played as herself but she next appears in the ending cutscene of Airfield Chase. She was freed with the rest of the caged birds in Smugglers' Plane - 30.

Angry Birds Rio (Rio 2)
She only makes a cameo appearance in the Rio 2 episodes when you use the "Call the Flock" power-up, where she might appear with the birds.
