The pilot reported that following departure he proceeded to practice maneuvers in the local area. According to the pilot no mechanical malfunctions occurred during flight. After flying about 45 minutes and during a turn, a brown bird suddenly appeared in the upper right corner of the windshield and collided with the airplane. A portion of the windshield broke out and the pilot lost partial control. The pilot was unable to maintain altitude and he made a forced landing in an open field. During rollout on uneven terrain the landing gear separated from the fuselage.
