I suggest that the bird in Laurie Knight's photos is a "juvenile" Noisy Pitta rather than an
"immature".
The "immature" is much more like an adult - without the white chin and throat of the juvenile but
with some colour at the gape.
Presumably Grant Brosie's image on BirdingOz is also of a "juvenile". The forum which David Stowe
referred to is not open to the general public and I didn't feel the need to register to check the
image.
The terms "juvenile" and "immature" are often very casually used in the field guides and by
birdwatchers - perhaps that is something which could be addressed in future field guides. None of my
Australian bird field guides shows an illustration of an "immature" Noisy Pitta but the Slater guide
(2004 reprint) shows a correctly labeled "juvenile" - which looks like Laurie's bird. Peter Slater
also did the Pitta illustrations for HANZAB and it is interesting to compare the differences in the
illustrations in the two publications.
