I saw a starling today, observing the scene but not joining in

A single starling is nothing to get worked up about, and I actually have no grudge against starlings to begin with. Native bird loss due to starlings is insignificant compared to bird loss due to human activities, and anyway, I live in a big city, so, you know, I'm not exactly expecting a rural idyll.

But that doesn't mean I want to feed so many starlings that they push out the birds I like more, like those woodpeckers. Still, I have a plan. I'll wait and watch, and if this becomes a problem I'll put out some feeders that are optimized for smaller birds only and cut down to exactly one tray feeder.
