NESTS—NIDICOLZE 629 
from Bauer’s drawing. The Phillip-Island Nestor may be distin- 
guished from both of the New-Zealand species by its somewhat 
smaller size, orange throat, straw-coloured breast, and the generally 
lighter shade of its tints. 
The position of the genus Nestor in the Order Psittact must be 
regarded as uncertain. Garrod removed it altogether from the 
neighbourhood of the Lories (Proc. Zool. Society, 1874, p. 597), to 
which indeed the structure of its tongue, as previously shewn by 
him (op. cit. 1872, p. 789), indicates only a superficial resemblance. 
Like so many other New-Zealand forms, Nestor seems to be isolated, 
and may fairly be deemed to represent a separate Family—WNestoridx 
—a view adopted by Count T. Salvadori (Cat. B. Brit. Mus. xx. 
Introd. p. viii.), and fully justified by a cursory examination of its 
osteology, though this has hitherto been only imperfectly described 
and figured (Eyton, Osteol. Avium, p. 72; A. B. Meyer, Abbild. von 
Vogel-Skeletten, p. 18, pl. 23). 
Further knowledge of this very interesting form may be facili- 
tated by the following references to the Transactions and Proceedings 
of the New Zealand Institute, ii. pp. 64, 65, 387 ; iii. pp. 45-52, 81- 
Brea 200.5 vi pps 114, 12851 p..340; x. p. 192; x1. pi 
377; and of course to Sir Walter Buller’s Birds of New Zealand, 
especially the second edition. 
NESTS, see NIDIFICATION. 
NIAS (Fr. Niais, and that from the Low Latin Nidaz, a nest- 
ling), corruptly “ Eyas” or ‘‘ Eyess,” a falconer’s term for a Hawk 
that has been brought up from the nest, in contradistinction to 
a “Haggard” or Hawk that has been caught wild. 
NIDICOLA:, a word used in this work in no systematic sense, 
but as a convenient term to indicate those Birds, the young of 
which remain in the nest for a shorter or longer time as opposed to 
Nipiruc#, or those whose chicks are hatched in a condition 
_ enabling them to leave their birthplace at once. The Midicolz, all 
of which have their eyes closed at coming into the world, may be 
divided into four categories, according to their initial state and the 
way in which they subsequently develop :— 
(1) Those born with a clothing of “Neossoptiles” (see 
FEATHERS, p. 243), as Accipitres, Alcidx (partly), Caprimulgi, Colum- 
bidx, Eurypyga, Heliornis (excl. Podica), Sphenisci, Striges, Tubinares. 
(2) Those born naked or nearly so, but soon acquiring a thick 
clothing of neossoptiles, often of complicated structure, as Ardex 
(+ Scopus), Cathartx, Ciconiz ( + Platalea), Podica, Steganopodes. 
(3) Those born naked, but with a few neossoptiles growing out 
of the tip of the ‘‘ Teleoptiles” (see FEATHERS, p. 243) as Passeres, 
Upupide. 
(4) Those born naked and never acquiring neossoptiles, nearly
