I'm not Rob, but I would say the platform needs to be
changed ASAP. The last thing an Osprey needs to be exposed to is
Arsenic. See link below.
Now they have changed the Arsenic to very high levels of
Copper which will corrode the connective materials (nails and screws).
Here's another link from Audubon in Omaha:
I don't believe there is a substitute for Mother
Nature. Once man gets involved, there always seems to be something bad -
whether they discover it right away or in the future.
It's not worth the risk, in my humble opinion.
I live in Southern California. The DFG is stocking
the lakes with trout here. It's such a joy to watch the Osprey dive for
fish. I think some of them have migrated down from the colder
Northwest.
