NOTORNIS HOCHSTETTERIA.B.M.
(Plate 34.)
- Notornis Hochstetteri A. B. Meyer, Abbild. Vogelskelett, Lief. IV & V, p. 28, pl. XXXIV-XXXVII (1883—South Island, New Zealand); Zeitschr. ges. Orn. II, p. 45, pl. I (1885—figures of the bird).
- Notornis mantelli (non Owen 1848!) Gould, P.Z.S. London, 1850, pl. 21; Trans. Zool. Soc. London IV, pl. 25 (1850); Gould, B. Austr. Suppl., pl. 76 (1869); Buller, B. New Zealand, pl. (1873); Sharpe, Cat. B. Brit. Mus. XXIII, p. 208 (1894).
The name Notornis mantelli having been based on a cranium and some leg-bones from the North Island, and the bones of a specimen from the South Island, showing marked differences, Dr. A. B. Meyer was fully justified in describing the latter form as different, under the name of N. hochstetteri.
According to the describer there are considerable differences in the cranial bones, but the comparison of the leg-bones shows such differences in size that these alone would be sufficient to separate the North and South Island forms. The femur of N. hochstetteri measures 109, that of N. mantelli 122, the tibia of the former 165, the tarso-metatarsus 109, the tibia of the latter 200, the tarso-metatarsus 129 mm. For further measurements see A. B. Meyer, Abbild. Vogelskelett I, p. 30.
The upper surface is olive-green with some slaty-blue shading, the quills are black with purplish blue outer webs; rectrices blackish, green on the outer webs. Head, neck, and under surface purplish blue, thighs more blackish. Under tail-coverts white, frontal plate and bill bright red, yellow towards the tip of both mandibles. Feet red.
Although this bird is evidently not extinct, a specimen having been captured as late as 1898, it seems that not many examples live at present in New Zealand, as they have been sought after a good deal, and yet only four have been taken so far, i.e., the two in the British Museum, one in the Dresden Museum, and the last-mentioned one.
Full accounts of the capture of this last specimen have been given in the Trans. New Zealand Institute, XXXI, pp. 146-150, and in Sir Walter Buller's Supplement to the Birds of New Zealand, I, pp. 66-74, where, however, the year of the capture is not mentioned, though one can guess that it must have taken place shortly before the articles on it appeared.
Habitat: Middle Island, usually called South Island, apparently nearly extinct.
