Dollarbird now at Booragoon Lake Perth WA

["Greg & Val Clancy" <>]

Hi Frank,

I am curious to know why you believe that the Dollarbird is a 'sub-adult'? 
It look like a juvenile to me.  I suppose it depends upon what your 
definition off sub-adult is.  Certainly a juvenile is a 'sub-adult' if you 
call anything younger than an adult a 'sub-adult' but I don't.  I usually 
reserve the term for a bird that is close to assuming full adult plumage, 
i.e. a late stage immature.
A juvenile bird is one that is still in the plumage that it had when it left 
the nest.
