Will never be able to tell where this un-banded bird is from. It’s not uncommon to have birds we’ve banded in previous years return to the Wpg area…always exciting to know they made it through the first couple years of migration.
Over the years there’s been a few birds for one reason or other that we haven’t been able to band.
Peregrines along with other birds seem to have a built in GPS that will bring them back to the same or general area of where they were hatched or nested .
All this is something we’ll truly never understand.
