Watching THE CUCKOO-LIKE BIRDS
THE PARROTS
The Nestor Parrots
(Subfamily Nestorince). — This is a very small group, comprising only a single genus {Nestor) and six nominal species, of which three are either extinct or of doubtful status. Entirely confined to New Zealand or adjacent small islands, they are birds of fair size, being from fifteen to twenty inches in length, and may be known by the compressed long bill, which is much longer than deep and has the culmen grooved along the middle, while the base of the lower mandible is partially hidden by soft, hairy feathers which project forward; the cere is also partly covered with hairy feathers.
The tarsus is relatively long and the bony ring about the socket of the eye incomplete, while the wings are long and rather pointed, the tail of moderate length, even at the tip, and with the shafts pointed and projecting beyond the webs. The tongue is provided with a fringe of delicate hairs at the extremity.
