K82 and K81 became a breeding pair in 2003; both were 5 years of age.
The resident female K82 hatched from an egg removed from the West End Nest in 1998 and was then fostered into the Pinnacle Rock Nest. K82 has orange wing blings on her wings.
The resident male K81 was hatched at the San Francisco Zoo in 1998 and then fostered into the West End Nest.
K81 started with two wing blings one on each wing, however, sometime in 2013 his left bling fell off. K81 has two ankle bands; a silver federal leg band on his right leg and an orange aluminum band with "7/L" on his left leg.
DDT pollution caused a rapid decline in the bald eagle population; causing the eggs to thin so many did not hatch. To promote the recovery of the bald eagle population eggs from this nest were removed a few days after they are laid and replaced with artificial eggs. The viable eggs were then artificially incubated then once hatched the chicks were fostered back into the nest so that the chicks could be raised by the parents.

2018 - A territorial dispute resulted in K82 having visible injuries to her face and both eyes; K82 left eye was particularly bad. A live cam is active on the pair's new nest but unfortunately as of Feb 25, 2018 there are no eggs yet.
Based on past experience, look for eggs in late February and early March, chicks in early April, and fledging from mid-June to early July.
