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
Hawking (birds) tight spaces. Birds in more open settings that sally after larger insects like bees, such as kingbirds and bee-eaters, benefit from longer, more pointed wings, which are more efficient because they generate more lift and less drag. Swallows and swifts, which glide about in totally open spaces, have even longer wings. Another function of long, pointed wings is to enable these birds to turn quickly and smoothly in mid-glide. The wingtips create little vortices of air, within which the low air pressure creates additional lift on the wingtips. Furthermore, long, forked tails provide additional lift, stability, and steering ability, which
