Narrative:
While on the fytte arrival into ord; we had a near midair collision with a glider. We were at 7000 ft doing 210 KTS assigned. I looked up and spotted this black spot floating in the air at our [12-1] position. I thought it was a bunch of balloons until it made a right descending turn. I realized that it was a glider and I took evasive action. I pitched up; turned right and shoved the power up simultaneously trying to avoid the glider. I did get a brief stick shaker activation. From the time I spotted the glider until our paths crossed; it was no more than 5 seconds. We gained roughly 400 ft above our assigned altitude and speed increased to around 250 KTS. We immediately reported a near midair with a glider and our deviation. We returned to 7000 ft; slowed back to 210 KTS and rejoined the arrival inside fytte. We landed 9L with no other problems.
