Exactly. Because the birds are ingesting the poisons and then moving from location to location, the poisons travel, too, unwittingly. What worries me most is that some whacko will propose "stopping the pollution" by eliminating the "culprit birds" instead of addressing the real problem (and we all know there are those types out there a-plenty, too).

So it is not really the bird droppings that are the problem, but the pesticides and mercury that are in the droppings? I guess then that bird droppings closer to civilization are even worse.
