The African Grey Parrot (Psittacus erithacus) is a medium-sized parrot endemic to primary and secondary rainforest of West and Central Africa. Experts regard it as one of the most intelligent birds. They feed primarily on palm nuts, seeds, fruits, leafy matter, and have even been observed eating snails. Their overall gentle nature and their inclination and ability to mimic speech have made them popular pets. This has led many to be captured from the wild and sold into the pet trade. The African Grey Parrot is listed on CITES appendix II, which restricts trade of wild caught species, because wild populations can not sustain trapping for the pet trade.
Grey parrots depend on large old trees for the natural hollows they use for nesting. Studies in Guinea and Guinea-Bissau have found that the preferred species of nesting trees are also preferred timber species. There is a positive relationship between the status of the species and the status of primary forest: where the forests are declining, so too are populations of Grey parrots.
General Batista Tagme Na Waie, also transliterated as Batista Tagme Na Wai (1949 – March 1, 2009) was chief of staff of the army of Guinea-Bissau until his assassination in 2009.
Na Waie was born in Catió. A participant in the junta that overthrew João Bernardo Vieira in the 1990s and a veteran of the Guinea-Bissau War of Independence, Na Waie was a member of the Balanta ethnic group. He had been appointed chief of staff as the result of the October 2004 murder of his predecessor, Veríssimo Correia Seabra; IRIN has described him as a "consensus figure put forward by the military establishment which the government felt forced to accept".
A "bitter rival" of Vieira, both before the junta (having survived Vieira's purges of the Guinea-Bissau military in the 1980s) and after Vieira's return to power, Na Waie reported surviving an assassination attempt in January 2009, when a militia assigned to the presidential palace opened fire on his staff car; the militia denied that this had been an assassination attempt.
On March 1, 2009, Na Waie was killed by an explosion in the headquarters of the Guinea-Bissau military. While witnesses reported seeing a rocket-propelled grenade, aides to Na Waie reported that a bomb was detonated under a staircase as Na Waie was heading to his office.
