Nitpickers are red birds found in the game Ice Climber. You will lose a life if one hits you, however you can also hit the Nitpickers with a hammer to defeat them. Defeating them is worth 800 points. When they appear, they always appear on the highest visible level. They will fly between levels, but will generally remain on one of the top two visible levels. Nitpickers also appear in the game "Donkey Kong Jr.", where they are enemies, also.
