Aliska, I went and looked them up, this pair have been together since the winter of 2007-8. She was about 4 years old when they first appeared.
They have successfully laid, raised and fledged:
2 in 2008
3 in 2009
3 in 2010
3 in 2011
So this is their 5th mating.
She laid the 2nd egg tonight!
I had no idea hat bald eagles mate for life! That’s pretty cool!
