If you have the opportunity to see a squirrel from behind the difference is unmistakable. Male squirrels have very large testicles. Boy squirrels have big puffy tails, and the girls only have non-puffy not fuffy. Black squirrels are extremly rare.
Yes it will kill squirrels since squirrels are like big rats, poison is poison and it sure is not the right thing to do even though its very tempting since they eat every pretty flower we have and make horrible holes. So better off setting a trap
These are the types of squirrels: *Fox Squirrels *Eastern Grey Squirrels *Western Grey Squirrels *Red Squirrels *Flying Squirrels *California Ground Squirrels Prairie Dogs may or may not be a part of the squirrel family. Hope this helps! :)
It depends on what kind of bird. Birds of Prey, like hawks and eagles, would eat squirrels. Other birds, like blue jays and cardinals, will not eat squirrels (mostly because a squirrel is just as big as them).
