Yes but bird aren't ornithologists. It's a bit like on Reddit, as a speaker of a language that's not so popular for learning, when there are some language learners asking questions, we get lots of confident but wrong answers about grammar or why something is said the way it is, or they confidently state its just an exception when there is actually a rule, or similar stuff. They often also confidently stick to false folk etymologies etc. Similarly people sometimes try to language-tutor their romantic partner and discover that it's actually not so easy. Just because you're a native speaker you are not good at explaining how the language works. Similarly even though you have a brain, you don't really know how it works.
