Birchfall

Birchfall is a light brown tabby tom with amber eyes.

Midnight
He was born in Midnight along with his now-dead siblings Larchkit and Hollykit. He survived the Great Famine and the Great Journey as the only kit in the Clan. He is from Dustpelt's and Ferncloud's second litter, and, as a kit, was very adventurous. When he was young, he went after some prey and nearly fell off the cliff in ThunderClan camp, surviving only because of Brambleclaw, who pulled him back.

Moonrise
In Moonrise, ThunderClan starts to run out of fresh-kill and one of Birchkit's siblings dies of starvation and cold.

Starlight
In Starlight, Birchkit first appeared alongside three ShadowClan kits - Toadkit, Applekit and Marshkit - who he was friends with. Later on in the book, Birchkit disobidently follows a patrol and almost falls over the edge of the quarry to his death.

Twilight
Birchkit becomes the first kit to become an apprentice in ThunderClan's new territory. His mentor is named as Ashfur, who is also his uncle.

Sunset
In Sunset, Birchpaw is sent out on an assessment by Ashfur, his mentor. Later, Firestar, who is caught in a fox trap, says that Birchfall had told him that Blackstar was waiting on ThunderClan's territory.

The Sight
In Power of Three, Birchfall appears as a warrior.

Dark River
In Dark River, he is on guard duty when Lionpaw and Jaypaw go to look at the stick by the lake. Birchfall likes to act wise and all-knowing, but he is still a young warrior. Earlier on in the book, Jaypaw pulls a thorn out of Birchfall's paw just before Cinderpaw is injured.
