These are the two Pied Harriers. One of them looks like an immature that is acquiring male adult plumage! In 2018 we were able to watch a Pied Harrier acquire male adult plumage.
We were able to observe him from August 2017 until July 2018. He had a string that was attached to his leg. Maybe someone tried to catch him and he was able to escape. The string made it easy for us to identify him.
These are photos from February 2019 of the possible 2nd male Pied Harrier in our refuge!
