Why is the conduction band of Si not monotonic?

A typical band structure of silicon is shown in the picture. If we consider a subband of the conduction band within the first Brillouin zones, we can clearly see that this subband is not monotonic. It involves more than one local minima or maxima points within the first zone, which confuse me a lot.

The second conduction band valley is only above the minimum of the first conduction band. Carriers above in kinetic energy may reside in either of the two conduction bands.
