  We report on bursts from the Soft Gamma-Ray Repeater SGR 1806--20 detected
with INTEGRAL in October 2003, during a period of moderate activity of the
source. The spectral and temporal properties of 21 short bursts are consistent
with those found in previous observations, even if these bursts are among the
faintest observed in the 15-200 keV range from this source. During some of the
bursts a clear spectral evolution is visible. The data also show, for the first
time, evidence for a hardness-intensity anti-correlation within SGR 1806--20
bursts.
