Identify is like recognize put it has more to it, so to recognize is something you see it and know what it is, usually you have seen it before
Identify you recognize something but then you give more information like naming it.
I recognize that type of bird, it is a blue jay...
See that bird? Now identify it...so i would then go look in a bird book until i found a picture of the same type of bird, i would look at the name of the type of bird, blue jay, and i will now have identifed the bird as a blue jay
Subtle difference i think
