Xenicus is a genus of birds in the family Acanthisittidae. It contains New Zealand wrens.




Species


New Zealand rock wren, Xenicus gilviventris
Bushwren, †Xenicus longipes (extinct)
South Island stout-legged wren, †Xenicus yaldwyni (extinct) – South Island, New Zealand
North Island stout-legged wren, †Xenicus jagmi (extinct) – North Island, New Zealand
Lyall's wren was classified as Xenicus lyalli but is quite divergent, so it is placed in its own genus, Traversia.




Taxonomy


The stout-legged wrens formed a species pair. They had reduced wings and robust legs indicating that they were adapted to a terrestrial existence and were either flightless or nearly so. Genetic evidence has indicated that the former genus Pachyplichas is nested within Xenicus, and stout-legged wrens must have evolved from a gracile-legged ancestor. A cladogram is given below.
