Yellowhead

The yellowhead or mohua (Mohoua ochrocephala) is a small insectivorous passerine bird endemic to the South Island of New Zealand. Once a common forest bird, its numbers declined drastically after the introduction of rats and stoats, and its IUCN conservation status is now near threatened. == Taxonomy == The yellowhead was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with the flycatchers in the genus Muscicapa and coined the binomial name Muscicapa ochrocephala. The specific epithet is derived from the Ancient Greek ōkhros meaning "pale yellow" and -kephalos meaning "-headed". Gmelin based his account on the "yellow-headed fly-catcher" that had been described in 1783 by the English ornithologist John Latham in his book A General Synopsis of Birds. The naturalist Joseph Banks had provided Latham with a watercolour painting of the bird by Georg Forster who had accompanied James Cook on his second voyage to the Pacific Ocean. The inscription on the painting includes the year 1774 and the location "Queen Charlotte's Sound". Queen Charlotte Sound is on the north coast of the South Island of New Zealand.
