I tried using 3M Hand Glaze polishing compound which normally takes anything off and the discoloration won't go away.

Is the paint ruined? Any ideas?

The bird must have eaten battery acid earlier in the day for this to happen.

the mark and see if you see clear coat actually missing. If you see a crater then that may have to be rounded off by a random orbital or rotary with the right polish and pad combo. Most bird crap is very acidic and will eat into the clear if it sits. I keep a spray bottle with water and a clean microfiber towel in the trunk for just such occasions. Bird crap marks show really well on dark colors.

it was on my new car and only had 1 coat of Liquid Glass on it. Never have had the paint marred before when LG was used I usually have at least 3 coats of the LG on the car. 3 coats seems to make the paint pretty impervious

Highly recommend a great polish for this: One Grand Special Touch

Try clay, if not, take to professional detailer. They can polish or wet-sand if necessary.
