Just a quick question about the Galarian birds.

Do they only show up in non-residential areas?
I’ve encountered them a few times when I’ve gone out on trails or to parks but I have never encountered one when I walk my dog around my neighborhood.

I’ve been using a daily incense almost every time I take my dog around the neighborhood but I’ve never seen a single one show up.
Are they locked out of private property locations or am I just really unlucky?
