given the toxicity of styrofoam, why introduce toxic material into an
environment birds are feeding in?

Sorry effi, it is not toxic. If ingested by a bird it may block the
digestive tract same as any other inert material. There is a difference
between blocking and being toxic. You pointed to a list about toys for birds
to play with.. That is different than insulating a window for a feeder.
While they should not eat any plastics, they can sit on it, nest on it,
sleep on it, and have no adverse effects EPS foam is used for coffee cups,
cooker, seafood shippers etc. It is allowed because it is on the GRAS list
and is NOT toxic.

It is recyclable, it saves energy, it is safely incinerated and gives off
18,000 Btu per pound when used to generate electricity in a trash to energy
plant. Oh, not all foam is Styrofoam. Only the product made by Dow
Chemical as that is their registered trademark for extruded polystyrene
foam.

Any other questions?
