Nycticorax caledonicus crassirostris
It was a bird endemic to Bonin island, Japan.
This species feed on fish, insects and possibly youn turtles. It was 60cm tall and it had two white plumes reached from its head to the back. Many birds was shoot by the early europeans that "found" the island but this was unlikely the reaon why the bird become extinct. Its more likely that introduced animals like cats and ratsmost likely got to the eggs and nesting sites were they quickly cut down the numbers. The last specimens of this subspecies was collected 1879 in its last refuge on the north of island called Nakondo Shima. All searches for the bird has since been fruitless.

Luther's Die ausgestorbenen Vögel... also gives 1889 as the last record.

 A rare specimen of the extinct subspecies of the New Caledonian Night-Heron Nycticorax caledonicus crassirostris. This subspecies once lived on the Bonin Islands. This subspecies became extinct in 1889, just 50 years after its first discovery. Causes for its extinction are probably introduced cats. Stuffed specimen exhibited at the Natural History museum of St. Petersburg, Russia. This Museum hosts 4 of the 6 remaining specimens. flickr.com/photos/92043060@N00/353236099/ |

The other two specimens at the NHM. Note that they are the Holotype and the last known specimen of this taxon.
Information in:
Knox, A. G. & M. P. Walters (1994). Extinct and Endangered Birds in the collections of The Natural History Museum.
Nycticorax caledonicus crassirostris
Bonin Night-Heron
Formerly occurred on Peel Island and Nakondo Shima in the Bonin Islands, where it nested in low trees near the coast. The last specimen was taken in 1889. The cause of extinction is unknown, but human interference is suspected.
Reg. no. 1857.10.16.66. From Bonin Islands, Japan. Date: 1827. Source: Collie, voyage of H.M.S. Blossom; J. Gould. Material: adult; whole/good skin. Holotype. Vigors, in F.W. Beechey, 1839, The Zoology of Captain Beechey's Voyage, p. 27. Presumably collected in 1827.
Reg. no. 1897.10.30.32. From Nakondo Shima; Bonin Islands; Japan. Date: 15/6/1889. Source: P.A. Holst; Seebohm coll. Material: Female, whole/good skin. Date taken from the register.

Can this tread move to Extinct Coots, Cranes, and Rails because the bird was already extinct 100 years ago? Why? Ciconiiformes are not Gruiformes. |

Osteological and historical data on extinct island night herons (Aves: Ardeidae), with special reference to Ascension Island, the Mascarenes and Bonin Islands Abstract Night herons of the genus Nycticorax and Nyctanassa are adept island colonisers, occurring on a number of oceanic islands and island archipelagos. Continental species and those inhabiting large islands are generally not considered threatened, whereas night herons restricted to small, oceanic islands are particularly vulnerable to human interference. As a result, six out of nine described species and one subspecies, all derived from Nycticorax nycticorax, Nycticorax caledonicus or Nyctanassa violacea, are now extinct whereas a further three extinct species await description. The extinct island endemics generally exhibit morphological adaptations to an insular environment and diet, such as an increase or decrease in size, robust jaws and legs, and smaller wings with associated reduced flying ability than founding stock. Here I present an osteological comparison along with historical descriptions of the extinct, oceanic island night herons, with special reference to the Mascarene and Ascension fossil species, and Bonin Island subspecies, and show the degree of morphological changes between the founding and island taxa. I further discuss the reasons why they became extinct. www.sciencedirect.com/science/article/pii/S0016699523000591?via%3Dihub |
