Mum and Dad (those are their names) have been on the current barge since 2015, but there were osprey on the 'old barge' prior to that, but not monitored, so it might have been Mum and/or Dad, but that is unknown.
So.. they are probably born in 2011 or 2012, but might be older than that even.
A rare opportunity to compare Dad on the left (or top) and Mum on the right (or bottom) as they ate the fish close after one one another on the same spot
Together on the nest:
Mum on the right, Dad on the left
