Birmingham had taken the lead after 15 minutes and were worth their lead at the break, but Boro fought back in the second half and deserved the point that they got.
The Reserves are still top of the Premiership Reserve League North but have played more games than the teams immediately below them.
Boro team:
Jones, Liddle, Grounds, Cattermole, Cooper, Wheater, Owens, Kennedy, Graham, Craddock, Johnson (Clough)
