I think it's too early to assume cause and effect. I've lived in this house
now for twenty years and I have Anna's at my feeders all year and Rufous
every summer between late March/early April and late July/early August.
What I see when the two species interact is that the Rufous, although
smaller, are more aggressive. I consistently see them chasing Anna's away
from the feeders. That's not an obvious parallel for the barred owl and
spotted owl situation or grey squirrel and red squirrel situation in the
UK.
