Flight Crew Took Evasive Action
Procedure
We were descending from 6;000 ft to 4;000 ft on an IFR flight plan. As we passed through about 5;500 ft the Pilot Flying (PF) saw an aircraft at our 1 o'clock. They appeared to be climbing. The PF disconnected the autopilot and stopped our descent and turned left. We missed the glider but were able to see the other pilot. The glider did not show up on our TCAS and approach was unaware of any aircraft operating near us. After passing the glider we returned on course and continued our descent. Approach was unaware of our deviation. We did report the near miss to approach.
Captain reported a Near Mid Air Collision with a glider that required evasive action.
