Extinct

Chatham Fernbird (Poodytes rufescens)


Taxonomy

French: Mégalure des Chatham German: Chathamfarnsänger Spanish: Zarzalero de las Chatham
Taxonomy:

Sphenœacus rufescens

Buller

, 1869,

a small rock isle, a satellite of Chatham Island

.

Usually considered a race of P. punctatus, but sometimes treated as separate species (perhaps more closely related to Fijian Megalurulus rufus). Differed from P. punctatus in its white vs brown-streaked grey chin to lower belly (4); strong rufescent tone of upperparts, wings, tail and flanks (2); bolder, blacker streaks on upperparts and flanks (2); and osteological features#R. Close in size to P. caudatus, which was previously also treated as a race of P. punctatus. Monotypic.

Distribution:

Pitt I and Mangere I, in Chatham Is, New Zealand.

The last record was from around 1892, soon after which the species is thought to have become extinct#R. The major causes were loss of its low brushland habitat through burning and through overgrazing by introduced goats and rabbits, and predation by cats and rats.
