The Bonin Grosbeak or Bonin Islands Grosbeak is an extinct finch, the only species of the genus Chaunoproctus. It is one of the diverse bird taxa that are vernacularly called grosbeaks, but it is not closely related to the grosbeaks sensu stricto. It was a retiring, although not shy bird, and was usually found singly or in pairs. It fed on fruits and buds which were primarily picked up from the ground or low shrubs; it rarely was observed to perch in trees, being apparently rather phlegmatic and somewhat reluctant to fly. Only one kind of vocalization has been described: a soft, pure and high note, sometimes short, sometimes drawn out; sometimes given singly, sometimes in a short series.
The Bonin Grosbeak is classified as Extinct (EX), there is no reasonable doubt that the last individual has died.

The Bonin Grosbeak was discovered by the Beechey Pacific expedition, which collected 2 specimens on Chichi-jima in 1827. The following year, Kittlitz took several more specimens, but he only gave the locality "Boninsima" (="Bonin-shima": Ogasawara Islands). Following the report of two shipwrecked sailors, picked up by Beechey, that the island would make a good stopover station for whalers, settlement was begun in 1830. More

Bonin Grosbeak a finch, and Bonin Thrush. The island was the only known home of the thrush and probably the finch, although the heron was found on Nakōdo-jima (also "Nakoudo-" or, erroneously, "Nakondo-") as well. The existence of the birds was documented by von Kittlitz in 1828, and five stuffed thrushes are in European museums. The Bonin Wood-pigeon died out in the late Nineteenth century, apparently as the result of deforestation or the introduction of alien mammals or from both causes. More
the Bonin Grosbeak Chaunoproctus ferreorostris and Bonin Trush Zoothera terrestris. Most of our knowledge of the birds of the Bonin Islands comes from the crew of HMS Blossom, who collected various species new to science. A second important source of information was the German ornithologist Friedrich von Kittlitz, who visited the island in 1828. That year he discovered a ground thrush which had been overlooked by the English. More
Just like the Bonin Grosbeak, the Bonin Thrush probably succumbed soon after 1830 to predation by the introduced mammals and habitat destruction. - ABOUT ME More
