arakso's Identifications

When I went in there was 1 dark-feathered young perched on a large limb west of the nest (in nest tree). I saw an adult perched on a power-pole on dam. It flushed and flew across lake and lit in a tree. I saw another adult perched in a favorite tree overlooking the longest bay. When I came back out, there was nothing that I could see in the nest and the young that had been perched on a limb was not there. I discovered a dark-feathered young perched in a pine tree about a hundred yards from the nest tree. So there is successful fledging of at least 1 young. I assume both young have fledged. I looked under nest, no dead or live young there.
