5 Dollars - Elizabeth II 4th Portrait - Night Parrot

The Night Parrot (*Pezoporus occidentalis*) was so rarely encountered through the 20th century that it was genuinely considered extinct by many ornithologists — no confirmed sighting for nearly a century until a dead specimen turned up in Queensland in 1990. A living bird wasn't photographed until 2013, by naturalist John Young, an event that made international news. The RAM issued this coin six years after that rediscovery, at a point when the species' total population remained effectively unknown.
