There now only remains to explain Te Poko Uri:
 
3. Te Poko Uri
Ga5-8 (118)

The wings of this fat bird are drawn as a separate unit, distinct from the bird itself, and presumably it is a 'glyph play' (analogous to word play). We can imagine the shape behind the bird as a viri glyph turned a quarter around, a method we have seen before:

viri Ga1-26 Gb1-6

However, there is an important difference: In Ga1-26 and Gb1-6 the 'person' and viri are integrated, not separate units. This wingless bird has not moved far from his egg we can see from his body form, it is a very young bird (which also explains why he is so fat). That the 'wings' indeed is viri, can easily be proved by counting, given that we understand also Ga1-1 as viri (a distorted variant):

116 = 4 * 29
Ga1-1 Ga5-8
118 = 4 * 29.5

With both Ga1-1 (Hanga Takaure) and Ga5-8 as viri glyphs, they must both be black, we know from earlier (the 29th night of the moon is black). A little fat black (uri) chicken sounds like the future great king of the island (Te Kioe Uri). But the king cannot be located at a viri point:

57 = 2 * 28.5
Ga1-1 Ga2-29
59 = 2 * 29.5
