future ornithologist?

Sometimes my child REALLY surprises me with the amount of knowledge he has at such a young age. We were hanging around the house this morning, and while I was getting ready in my room I heard Camden say "I just saw a Speckled Warbler outside on that tree". I laughed in my head thinking, that's a funny word. One thing you have to know about Camden is that he's always making up silly words. Well, after a minute I thought, that does sound like a real thing actually. So, I googled "speckled warbler", and sure enough, it's a bird. A very specific type of bird I might add! Where did he learn this, you are asking? I HAVE NO IDEA!
