Hey Gene,
For the squirrels try putting out cracked corn and large sunflower seeds,,,, the tree rats love them :)
As for the starlings,,,,, the adults are easily recongnized by their black overall color, white speckled breasts and of course their bright yellow beaks. The juveniles can be a little difficult to I.D. sometimes due to their more subdued colorings, but there's no missing the adults :)
In NY starlings are considered pests, are totally legal to shoot anytime and in any numbers,,,, I think most of the rest of the states classify them the same way, but of course it's always best to check your states regulations prior to shootin anything.
I'll keep ya up to date on the "brew" and how it works.
Jeff
