Does anyone know where the scrub jay spawns? I'm guessing it's found in spots like Delphi, because it's found in the Western US, such as Florida. I haven't seen anything, and Bird watching is almost over!

if a bird doesn't have a place in its name, it can be found anywhere.

They can be found anywhere, however there have been some issues with the birds not showing up because they are being overwhelmed by the floating flowers from Survival

Bird watching floating items clashing with survival?

If you are having trouble finding it in the realms, you can purchase or borrow one from another user to show Rosemary, and then sell it again when you no longer need it.
