Aa6-59	Aa8-6

At this point I can reuse earlier work (documented under 'signs' at GD11 in the glyph dictionary):

I once again scrutinize Fischer's pictures of the Tahua text. Yes, I can now too see that Aa5-74 is big. I also think I was right in regarding Aa6-59 and Aa8-6 as narrow. But how difficult it is to observe this!

There are obvious marks in the rongorongo texts and then there are such hardly noticeable marks that one wonders how the creator thought they could be seen. Maybe people were more observent in those days?

Is Aa5-9, the obviously marked bird, indicating the 'knee' (va'e) of midsummer? If so, then Aa5-10 presumably represents the new ta season, appropriately with the wings at the back (tu'a).

On side b the opposite reversal has a bird with wings at the back superseeded by a bird showing a front view.

Aa5-9 has a wing similar to the curious one in Aa2-85:

Possibly a weaker variant of the sign is seen also in Ab7-29. The other wing in Ab7-29 has a 'bulbous' tip, which maybe is a repetition of the one in Ab7-28.

Aa5-11 and Aa5-13 exhibit 2 'eyes' (seasons), while Ab7-30 and Ab7-32 has 3. Given that I have understood the general pattern expressed by the text correct, this agrees with what we can read at the beginning of side a:

The form of the beak in Aa5-9--10 suggests (according to my earlier thoughts) kena:

... Another type of bird looks like this:

where the difference lies in the form of the beak, no bird of prey this. Possibly it is a kena:

Kena = A sea bird, with a white breast and black wings, considered a symbol of good luck and noble attitudes. The first month is called He Anakena. And Anakena is the place where the legendary Hotu Matu'a is said to have come ashore. Ana means cave, i.e. a place for birth ...

In Barthel 2 we can read:

Kena, the name for the booby, is also an eastern Polynesian name. Line 18 of the creation chant lists as the mythical parents of kena 'Vie Moko' and 'Vie Tea' (PH:520). The 'lizard woman' (vie moko) and her younger sister the 'booby woman' (vie kena) were considered the originators of tattooing (ME: 367-368).

The 'white booby woman' (vie kena tea), together with other deities, protected the eggs of sea birds (RM:260). She might even be considered to be the female counterpart of the supreme god Makemake. In modern Hangaroa, vie kena tea is a term of endearment for a beloved wife whose well-rounded body and light skin is being praised ...

 

... This is the largest booby ... Adults are white with pointed black wings, a pointed black tail, and a dark grey facemask. The sexes are similar, but the male has a yellow bill, and the female's is greenish yellow; during the breeding season they have a patch of bare, bluish skin at the base of the bill. Juveniles are brownish on the head and upperparts, with a whitish rump and neck collar. The underparts are white. Adult plumage is acquired over two years. The Masked Booby is silent at sea, but has a reedy whistling greeting call at the nesting colonies. While on the breeding grounds, these birds display a wide range of hissing and quacking notes. It nests in small colonies, laying two chalky white eggs on sandy beaches in shallow depressions, which are incubated by both adults for 45 days. Normally only one chick fledges.

Masked Boobies are spectacular divers, plunging diagonally into the ocean at high speed. They mainly eat small fish, including flying fish. This is a is fairly sedentary bird, wintering at sea, but rarely seen far away from the breeding colonies ...

45 days they need for the two 'chalky white' eggs to hatch, i.e. 1/8 of 360 days. One of the two chicks is sure to die. 'If both eggs hatch, the elder chick will push its sibling out of the nest area, leaving it to die of thirst or cold ... The kena is white on her back (and black on the lower part of the wings), while manu tara is white on her chest (and grey or black on her back). Which reminds me about moa tu'a ivi raá, the hen with a bright yellow back. Boobies are 'spectacular divers, plunging diagonally into the ocean at high speed', a description which is quite suitable if we consider them to be symbols for how the sun dives down in the evening at the western horizon. They lay their eggs 'on sandy beaches in shallow depressions', e.g. such a beach as is found at Anakena.

Contrary to what I have earlier suggested, I now think that the beak of the booby has a shape which is different from the one in the picture above:

But I have a new suggestion, viz. that the left wing in Aa2-85, in Aa5-9 and possibly also in Ab7-29 are drawn in order to allude to the beak of the kena:

     

The booby is a fat bird (... vie kena tea is a term of endearment for a beloved wife whose well-rounded body and light skin is being praised ...), having been well fed during the season of plenty. She is (in form of vie) the originator of tattooing (together with her elder sister vie moko), i.e. she originates the ta season, I think. She is white, yet produces black. In the bird list she is located where we should expect her to be:

I have black-marked kena to indicate her character as originator of the season of ta.

I notice that the ordinal numbers of the ta-birds sum up pairwise to 20 (9 + 11) respectively to 30 (14 + 16). Altogheter we get 8 + 20 + 30 = 58 = 2 * 29.

We should complete the investigation of the GD11 birds in Tahua by looking on side b. Their number is 9 * 6 + 5 = 59:

After eliminating the complex glyphs I have these 20 left:

Once again we rely on the earlier thorough investigation looking for small signs, and find that the 6 + 6 = 12 non-red birds above dwindle down to just 2:
