tui

When a 'tui' or a bellbird pops open a bud, all four petals spring back, and as the bird inserts its beak into the corolla to drink nectar, its head often brushes pollen onto the receptive stigma.

First there's the 'tui' , a grackle-size bird with blue-black and purple hues, filamentous white feathers woven through its nape and a white, tufty throat pompon worn like a bow tie.

In addition to the 'tui' , another New Zealand species of honeyeater, known as the bellbird for its clear, bell-like call, commonly opens mistletoe flowers.

Furthermore, when the bellbirds, 'tuis' , kaka, and native insectivorous birds attempt to feed on native invertebrates, they again face competition from wasps, which devour spiders, caterpillars, ants, bees, and flies.

Bell-birds and 'tuis' - forest birds in the nectar-feeding family called honeyeaters - have brushlike tongues that enable them to lap up honeydew drops easily.
