Garuda

This hawk is the personal summon of Sasuke Uchiha.

Appearance
While resembling a normal hawk, it is much larger in terms of size to one. It was depicted as being brown in colour and has dark markings around its eyes as well as along the sides of its beak.

Five Kage Summit Arc
During his fight with Danzō Shimura, Sasuke summoned this hawk to avoid falling off the Samurai Bridge after being injured by Danzō's Wind Release: Vacuum Sphere. Sasuke later disembarked from the bird in order to evade the Wind Release: Vacuum Wave while it flew towards them.

In the anime, the hawk further assists Sasuke in his battle by using its body and the wind to direct one of Danzō's wind-enhanced shuriken and sending it back at him, severing Danzō's right arm and having him release his grip on Sasuke, thus allowing Sasuke to slash Danzō in the chest; in the manga, it was Sasuke who severed the right arm with his Sword of Kusanagi. After Sasuke killed Danzō, the hawk was seen flying away from the battlefield.

Infinite Tsukuyomi Arc
Sasuke summons the hawk when he makes his second assault on Madara Uchiha.

Later, after Kaguya Ōtsutsuki revives herself via using Black Zetsu and Madara's body as a medium, Sasuke summons the hawk to prevent himself from falling into lava when Kaguya teleported Team 7 into a volcanic area of an alternate dimension, and then catching Naruto along the way. Kaguya then launches her hair at the hawk as needles, striking its tenketsu in the wings, disabling its ability to fly. Naruto saves both the hawk and its summoner with his chakra arms, along with the rest of Team 7. The hawk then returns to its own location.

Trivia

 * Sasuke was first seen riding a hawk on the cover of chapter 1.
 * In the anime when this hawk débuted, a lot of the hawk's design is lost from the manga and the markings on the side of its beak are noticeably missing.
 * Since all summoning animals are located in the same dimension as humans, Sasuke's hawk should've been caught in Infinite Tsukuyomi, as other animals were seen caught in the genjutsu. However, Sasuke's hawk seem to have bypassed the genjutsu. It is unknown if it was by chance, if all summoned animals were exempt from the technique, or if Sasuke was able to break the genjutsu when summoning it.
