Yellow Warbler...juvenile? immature?

[xpoetmarcr]

Since the youngster here was being fed by a Yellow Warbler, I bet it's safe to say this is a young one.  My question is whether a juvenile or immature?  What's the difference, or are those descriptions interchangeable?  Or...is a juvenile younger than an immature or vicey versy?

Can you tell I'm a bit confused with those terms? 

Thanks for the help.

I think this post does a good job of explaining the difference:

Basically, any bird that is not an adult is an immature. Juvenile is a more specific term that refers to the juvenile plumage, which can last for different lengths of time.  By the way, these are great pictures!
