people thik hummbirds

I just received a typo report on one of my books.

My line: Imagine if you went to a well-respected website and found this sentence: LOLZ can u believe sum people thik hummbirds are from Florida?

User note: “people thik hummbirds are from” should be “people thik hummingbirds are from”

REALLY?? First, they’re reporting a typo on that line? And second, that’s the thing that stood out to them?
