Northern sportive lemur have large bacteria-filled ceca, which helps them to digest plant matter such as cellulose and break it down into sugars and starches. The northern sportive lemur is preyed on by the native Malagasy tree boa, which hunts the lemurs while they are sleeping in tree holes. Large birds of prey, Falconiformes and Strigiformes, are also natural predators of the lemurs. Along with these ecological threats, the arboreal lemur species are also highly threatened by human charcoal production, which still continues to remove the only remaining forest habitat of the lemurs, greatly restricting their range. "L. septentrionalis" is also illegally hunted
Stymphalian birds Stymphalian birds The Stymphalian birds ( ; , "Stymphalídes órnithes") are a group of voracious birds in Greek mythology. The birds' appellation is derived from their dwelling in a swamp in Stymphalia. The Stymphalian Birds are man-eating birds with beaks of bronze, sharp metallic feathers they could launch at their victims, and poisonous dung. These birds were pets of Artemis, the goddess of the hunt or have been brought up by Ares. They migrated to a marsh in Arcadia to escape a pack of wolves. There they bred quickly and swarmed over the countryside, destroying crops, fruit trees, and townspeople.
