Sparrowtail/Main article

Sparrowtail is a large, brown tabby tom.

He is born as Sparrowkit to the ShadowClan queen Kinkfur, and has two sisters, Mistkit and Dewkit. Years later, he is shown as a warrior with the name of Sparrowtail, along with Mistcloud. He is also the father of Needlepaw, and the mate of Berryheart. However, his mother Kinkfur dies due to yellowcough, and he grieves for her along with Mistcloud and Ratscar, who was a close friend of his mother's.

When Needlepaw instigates a rebellion against Rowanstar, he is surprised at his daughter's actions, and is ultimately heartbroken when she leaves with Juniperpaw and Sleekpaw. Shortly after, Berryheart leaves with two of her siblings, and Sparrowtail agrees with the majority of the ShadowClan cats that Rowanstar is not a strong leader, and stays with the majority of ShadowClan when Darktail takes over, merging the cats to become The Kin. However, like the majority of the ex-ShadowClan cats, he grows to regret his betrayal after seeing Darktail's true nature, and successfully escapes and reunites with Berryheart. He solemnly informs his mate that Needletail is being held prisoner by Darktail, and the two mates are reunited with Cloverfoot and Rippletail.

The four are eventually discovered by Tigerheart and Spire in an abandoned Twoleg nest, and Berryheart revealed to expected hers and Sparrowtail's second litter of kits. The four join up with Tigerheart's patrol, and Sparrowtail soon becomes the father to Spirekit, Hollowkit, and Sunkit. He witnesses Tigerheart's death, and, along with Rippletail, carry Tigerheart's body back to ShadowClan. He is present during Tigerheart's resurrection as Tigerstar, and rejoins ShadowClan with the rest of his Clan. Following the reunification of his Clan, Tigerstar appoints Sparrowtail the mentor of Cinnamonpaw.
