Hi all Many of our corvine-related passerines are quite different in the way they attain adult plumage as compared to things like finches, swallows etc. Golden Whistler actually takes years to attain full, adult male plumage. Juveniles undergo a quick partial moult into the orange-winged first immature plumage soon after leaving the nest, this is a distinct plumage & is a good way of telling the age of a bird, especially as these birds have a tendency to wander around & can be seen in unusual places sometimes. HANZAB says that adult male plumage is attained after 3-4 years & there are transitional plumages between. The female looks like an adult female in it’s second year, after it’s first complete moult. I hope this helps-Kevin Bartram _______________________________________________ Birding-Aus mailing list Birding-Aus@birding-aus.org To change settings or unsubscribe visit: http://birding-aus.org/mailman/listinfo/birding-aus_birding-aus.org
