If your date palm can be identified as Phoenix dactylifera or Phoenix reclinata then it should be edible. Most date palms if not all are edible. I dont know of any off hand that are specifically toxic. Pinto (maybe Pindo palm you mean?) Butia capitata also has edible fruits. I have seen bats, squirrel, raccoon and crows eating them locally. Getting them to eat it might be another story..

Thats just my point of view as a botanist...
