Description
The tui is a large honeyeater, 27 to 32 cm (11–13 in) in length. The Chatham Islands subspecies is larger on average than the nominate subspecies, and heavier. Males tend to be heavier than females. Nominate males weigh between 65–150 g (2.3–5.3 oz), and females 58–105 g (2.0–3.7 oz). Males of the Chatham subspecies are 89–240 g (3.1–8.5 oz) and females 89–170 g (3.1–6.0 oz). At first glance the bird appears completely black except for a small tuft of white feathers at its neck and a small white wing patch, causing it to resemble a parson in clerical attire. On closer inspection (see image) it can be seen that tui have brown feathers on the back and flanks, a multicoloured iridescent sheen that varies with the angle from which the light strikes them, and a dusting of small, white-shafted feathers on the back and sides of the neck that produce a lacy collar.

Feeding Habits
Nectar is the normal diet but fruit and insects are frequently eaten, and pollen and seeds more occasionally. Particularly popular is the New Zealand flax, whose nectar sometimes ferments, resulting in the tui flying in a fashion that suggests that they might be drunk. They are the main pollinators of flax, kowhai, kaka beak and some other plants. Note that the flowers of the three plants mentioned are similar in shape to the tui's beak—a vivid example of mutualistic coevolution.
Habitat
Tui are found through much of New Zealand, particularly the North Island, the west and south coasts of the South Island, Stewart Island/Rakiura and the Chatham Islands—where an endangered sub-species particular to these islands exists. Other populations live on Raoul Island in the Kermadecs, and in the Auckland Islands (where, with the New Zealand bellbird, it is the most southerly species of honeyeater). Populations have declined considerably since European settlement, mainly as a result of widespread habitat destruction and predation by mammalian invasive species. Nonetheless, the species is considered secure and has made recoveries in some areas, particularly after removal of livestock has allowed vegetation to recover. Predation by introduced species remains a threat, particularly brushtail possums (which eat eggs and chicks), cats, stoats, the common myna (which competes with tui for food and sometimes takes eggs), blackbirds, and rats. Tui prefer broadleaf forests at low altitudes, although have been recorded up to 1500 metres. It will tolerate quite small remnant patches, regrowth, exotic plantations and well-vegetated suburbs. They are one of the most common birds found in urban Wellington. They are usually seen singly, in pairs, or in small family groups, but will congregate in large numbers at suitable food sources, often in company with silvereyes, bellbirds, or kererū (New Zealand wood pigeon) in any combination. Generally, when interspecific competition for the same food resources among New Zealand's two species of honeyeater occurs, there is a hierarchy with the tui at the top and bellbirds subordinate. The latter are thus frequently chased off by tui at a food source such as a flowering flax plant.

General Info
Behavior
Male tui can be extremely aggressive, chasing all other birds (large and small) from their territory with loud flapping and sounds akin to rude human speech. This is especially true of other tui when possession of a favoured feeding tree is impinged. Birds will often erect their body feathers in order to appear larger in an attempt to intimidate a rival. They have even been known to mob harriers and magpies. The powered flight of tui is quite loud as they have developed short wide wings, giving excellent maneuverability in the dense forest they prefer, but requiring rapid flapping. They can be seen to perform a mating display of rising at speed in a vertical climb in clear air, before stalling and dropping into a powered dive, then repeating. Much of this behaviour is more notable during the breeding season of early spring—September and October. Females alone build nests of twigs, grasses and mosses.
