Is it possible to create a legend in a pairs() plot?

For example, suppose I have the following R codes:

 pairs(iris[1:4], main = "Anderson's Iris Data -- 3 species", 
       pch = 21, bg = c("red", "green3", "blue")[codes(iris$Species)])

How can I created a legend that shows which colour represents to which
Iris species?
