We present a search for neutral hydrogen (HI) emission from optically
identified dwarf galaxy candidates in the larger M81 group area.
Of 136 candidates, 68
galaxies have been detected (this corresponds to a detection rate
of 
49%). Most of the detected galaxies are background
objects and fail to be classified as dwarfs. Many known dwarfs
in the M81 group have been detected, but no new members have been
discovered.
