Galarian bird question.

Hey guys! So, I’ve been hunting the galarian bird for a good month now- and i’m genuinely curious about something..

So-. I’ve finally found a spawn spot!! It spawned 2 times in the last 3 days, in the same proximity.

My question is: it’s been a Zapdos each time. Does that mean, it’s only zapdos spawn location? Or is it random between the 3 galarian birds??

For anyone asking… it vanished both times ( of course 🙂 )
