A: The “race” name or subspecies name for the North America Tyto is "pratincola"
Tyto alba - the common Barn owl (pratincola) from North America, Bermuda, Bahamas and Hispaniola. This race is similar to the European birds, but it is larger, with stronger legs and feet. The plumage is slightly darker too.
The scientific name is derived from the Greek word "tuto", meaning owl or, more specifically, night-owl & the latin word for "white", so literally means "white night owl".
