All parts of this plant contain cyanogenic glycosides, which are capable of producing hydrogen cyanide (prussic acid) when the plant is crushed or damaged by eating.  Hydrogen cyanide inhibits oxygen utilization by the cells in the animal's body, and in extreme cases can cause suffocation. 

Although we would not classify Bird's Foot Trefoil as highly toxic, we would not recommend deliberately feeding it to your tortoise.
