Norwich moved to within two points of the Sky Bet Championship play-off places after beating Birmingham 2-0 at Carrow Road.
First-half goals from Cameron Jerome and Timm Klose helped the Canaries claim their fifth home win in six league games.
Birmingham dominated possession for long periods and had their chances, especially in the first half, but the fact remains that they are now without a win in nine games under new boss Gianfranco Zola.
There were opportunities at both ends in a bright opening, with Lukas Jutkiewicz testing John Ruddy with a snap-shot and Jerome firing straight at Tomasz Kuszczak from a better position.
