This took me about a month to two to figure out. The sound you are getting is an alert from the navigation that it is telling you caution ahead. It will bird chirp if the speed limit is dropping soon or if there is a very sharp turn coming up. Keep the map screen on and test it out in a area where the speed limit is dropping. You may have to go over over the speed limit by at least 6-7 miles per hour. It drove me nuts because they don't mention it in the manual or on the youtube videos....
