I have to agree with your conclusions re why groups of songbirds suddenly appear at feeding stations. Of course, you can add coincidence to the mix. As far as typical mixed flocks out there in the woods (e.g., , predator-alert protection figures in the equation, although it's quite selfish in the evolutionary sense), I don't know the full story, but thanks for getting me interested. To the journals!
In my case, we had a junco attack a few weeks ago, with a cardinal, and, thanks to a small hybrid tea rose (don't cut them back in the fall; winter breakage is usually minimal, or easy to fix in April), a mockingbird, a species on an unprecedented (aside from our three European transplants) range-expansion rampage.
I became aware of the presence of the mocker when Margaret begain her familiar mimidophile shrieking before she ripped the bathroom door off the hinges and crashed through the heavy plate-glass sliding doors leading to the feeders ...
It's been pretty quiet out there since. We all have to deal with such adversity at times. Or do we?
