I think your hypothesis is a good one. I've tracked some CBC data in Calif
and Washington. EUCD shot up quickly and, in many places, have now tempered
to half that level. I can tell you that in my neighborhood (Port Townsend)
the small flock is worked by Cooper's and Sharpies daily (though their
numbers haven't really changed). This is one of the theories for the crash
of the Spotted Dove in Los Angeles, which is now all but extirpated.

It is interesting that these natural cycles of the rise and fall of
invasives can take decades.
