Some distance north of Yakumo there is another good birding spot where there are normally a few eagles in winter. Usually 1 Steller’s and several White-taileds. These are probably more ‘generalist’ feeders that at Yakumo and are not so tied to a single food source. Hardly any at Yakumo now due to the lack of salmon this year.
A couple of days ago there were at least adult 3 Steller’s there. Were 1 or 2 of these refugees from Yakumo?
