I have searched for these issues, but saw that they were "resolved". These are not resolved, as I have had them in the last couple of days.
-Parrot dismounts when hitting objects from above. Duplicate by standing above a block and hitting it with a tool while having a parrot mounted. Parrot will fly off in the direction the player is hitting in, directly in aim of the tool the player is using (I've killed three parrots accidentally this way).
-Parrot teleporting. [Listed as resolved, still not though] Duplicate by having a parrot sit anywhere, (I had mine in an enclosed space) leave alone for several minutes, come back. Use /warp [location] and /home [home name] to exactly duplicate. Parrot should be flying several blocks away from where it was seated.
-Parrot dismounting while jumping down from multiple blocks. Duplicate by climbing up two to five blocks from a level and jump down.
