What is the difference between immature & juvenile birds?

I have been wondering, do any of you guys know the difference between juvenile and immature birds? A lot of websites all say different things, so I'm not sure what is true!

As far as I can tell they're one & the same. The words are used interchangeably. Whether that's the case at a scientific level I'm not sure.

Juvenile birds are young, immature birds flash their bum and raise their middle wing feather at passersby :)

j/k - as Woko says, I think they are one and the same.

When in doubt use 'Immature' for any bird that is not an adult. 'Juvenile' is more specific, describing a bird still in its juvenile plumage. This plumage is held only briefly for many songbirds (just a few weeks after leaving the nest) or up to a year for some larger birds like hawks. Once a bird has molted out of this plumage it is no longer a juvenile. If you can't determine this, but know that the bird isn't an adult, just use 'Immature'.

Thanks, cathy. That's consistent with walterr.ruiz' post. I shall tuck the information in my hump for future use.

Great to know the correct difference in the terms. 

I've sometimes been guilty of saying "juvenile", when I didn't really know what I was talking about!  I'll stick to "young" from now on. :-)
