Poison berries?

Stacy,
	
	Not all poisons are toxic, to the same extent, to all organisms.
Two quick (admittedly oversimplified) bird-based thoughts:

1)  	Such differential toxicity may result in some type of "directed" 
dispersal strategy; i.e., perhaps the seeds are only "properly" dispersed by a 
certain type of bird (which, of course, isn't affected by the toxin).  
Perhaps some type of non-animal seed dispersal strategy has evolved.

2)	Perhaps the toxins don't effect birds (in this example) at all but 
instead are preventing some type of herbivory.
