Oology looks like it's missing some letters, but it's actually not. What does an oologist study?

An oologist is into birds' eggs of all shapes and sizes. The word is derived from the Greek "oion," which means egg. While it's a scientific term, it can also mean someone who collects wild birds' eggs, sometimes called egg collecting (for obvious reasons).
