Consequently, each species of army ant has symbiotic relationships with about ten bird species. With the jungle being cut down, the army ants need an area of at least 100 hectares of protected forest if they are to survive. But the protected areas are too small for the birds. With the ants disappearing from outside such protected areas, the birds face extinction.
因此，當地每種軍蟻都有大約 10 種鳥類與之共生，在砍伐森林的壓力下，軍蟻需要上百公頃的保護區才能生存，許多鳥類就因保護區過小、軍蟻消失而跟著瀕臨滅絕。
