We found an eagle with a wing tag E4 during June surveyes. The eagle is a male at the nest M40-95 on the Chelomdja River.
This nest was occupied in 2009 and produced first chick only in 2011. Mr. Ueta an H. Nakagawa wing-tagged this eagle on 16 February 1995 as 5 years old adult. They trapped it at Furen lake, Hokkaido, N43°21'15", E145°16'50". This means that the eagle was first breeding at age of 19 years old, and it is now 22 years old! This is unbelievable!
