I have seen those fairy wrens but they are not ubiquitous creatures like magpies or others on the list. I would have liked to have seen a lot more love for the king parrots, the most trusting of birds, a joy to have perched on your arm sifting through the seed in your hand for the sesame seeds. I guess only those who live in certain environments get to interact with these birds.I wouldn't get too close to an emu - they're pretty vicious. They're aggression would make them a good emblem. They also run faster than Collingwood players. Rather than the Irish, we really should look at recruiting a few emus.
Gang gangs would also make a great emblem for a team sport. They arrive in a loud noisy pack and then run amok - Melbourne's second half could very well have been the work of a gang of gang gangs.
In terms of the commonality of blue wrens, have you never been to an urban park or garden- my research tells me they're common there? You can tell by the website name "backyard buddies" that this source is incredibly well fact checked and reliable, and it has been selected to be published on the internet after all:
Superb Fairy-wren - Backyard Buddies
In the Superb Fairy-wren family the father gets all the good looks! The bright blue male can be seen with his harem of brown females.backyardbuddies.org.au
Where are Superb Fairy-wrens found?
Superb Fairy-wrens are found in Tasmania and throughout eastern Australia to the south-eastern corner of South Australia.
Like most small birds, they can be found wherever there are dense shrubs and bushes. They are common in urban parks and gardens, and can be seen in small social groups of one dominant male and several females and young birds.
