Australian Logrunner
Orthonyx temminckii
Logrunners as a group are characterised by their distinctive tail feathers where the rachis (or central shafts) of the tail feathers protrude and are stiffened. The broad tail of the bird is less than four inches (10 cm) in length and the strong protruding rachis at the ends of the tail feathers are almost void of the usual barbs, giving the feather the appearance of spines. This appearance gives rise to some of the common names for the bird such as spine-tail or spine-tailed logrunner. There appears to be some debate about the number of tail feathers possessed by the Australian logrunner.
