Falco peregrinus pealei、オオハヤブサ

It's the first time I've watched a Falco peregrinus pealei , but I can't instantly tell the difference between the Falco peregrinus japonensis and the Falco peregrinus pealei .

According to Wikipedia,

In Japan, the subspecies peregrine falcon inhabits year-round (resident birds), and (the subspecies peregrine falcon (Falco peregrinus pealei) rarely flies in winter due to overwintering.
