The aspect related to the subsistence pointed for Fernandes (1963) follows the logic of a search for good areas agricultural, next the water courses candy and the forests for collection of fruits and hunting. Staden at the beginning of the nineth chapter of its exemplifica chronicle the search for the penalties used in the rituals: To the foot of the island, in which I was imprisoned, it has one another small island, where if they nestle maritime birds of Uwara name (mirim will guar -). The indians had asked to me if its enemies Tuppin Ikins had been this there anno, to apanharem the birds and the younglings … esteem pennas very daquelles birds, because all its ornaments are generally of pennas. (Staden, 1930.

p 62) The search for penalty of birds together with areas of fishes stimulated the contact between enemy peoples, creating litigation areas. Such areas had for peculiar characteristic in view of the construction of the villages, the use of caiaras double, absent in had areas as safe. The village of Ubatuba where Staden was captive serves as example of stuck social group in the limit with villages and enemy populations, having in malocas predominantly warlike populations in constant migration, still conserving the custom to deposit in its pales the heads of the enemies decapitated. Although the nomadismo and of the differences with relation the areas next or not to the enemies, the villages tupinambs looked for to fix themselves in ample areas, with the distribution of fertile lands happening in independent way, where each father of family received a piece from land that varied to plant cassava mainly. (FERNANDES, 1963) the amount of malocas in the villages is subject of certain quarrel for the sources: Gndavo (1980) affirms that tupinambs northeast constructs villages with 7 or 8 collective habitations, Staden speaks in only 7, Lry speaks that inside of each maloca lived about 600 people, without citing however how many of them plausvel of Alfred Mtraux existed emJaboraci.Para Fernandes the idea more, whose amount of habitations varied between 4 and 7, having between 50 and 200 individuals divided in about 60 farms of 12 feet (for maloca) varying how much the polgenas relations and reserving to morubixaba and its family the center.
