Phil, I cannot speak to Australian birds, but here in Arizona, the Cactus
wren will expel its tail feathers when frightened or held by the tail. I
have captured Cactus Wrens that got into the house and most always ended up
with a handful of tail feathers.
Does this method of survival exist with some Australian birds?
