[Tweeters] Request for information on local WA Bald Eagle

Last Friday, 26 February, we found an adult Bald Eagle already incubating
in a nest near Everett.
This seems quite early to me and I was wondering if anyone else out there
is seeing this behavior right now in your local nest(s).
If you live from Seattle north and know of any currently active eagle
nests, I would be grateful to learn what you are seeing.
Although I am told by Martin Muller that Bald Eagles can engage in false
incubation for several days prior to egg- laying, I am defining incubation
for this survey as being an adult lying down horizontally in the nest for
an extended time period, let's say 15 minutes or more.
We know that climate change is advancing breeding activity dates in many
species of birds.
I am curious if this might include Bald Eagles in our area too.
Perhaps someone is already looking at this?
In the meantime, I will start checking more nests and also look at the
literature for egg dates.
