African Pied Hornbill is a common resident breeder in much of equatorial Africa from The Gambia to western Uganda and northern Angola. This is a bird mainly of forest habitats. The female lays up to four white eggs in a tree hole, which is blocked off during incubation with a cement made of mud, droppings and fruit pulp. There is only one narrow aperture, just big enough for the male to transfer food to the mother and the chicks. Odzala Wilderness Ngaga camp, near Odzala-Kokopua National Park, Republic of Congo
Road through the Congo forests of Odzala-Kokoua National park outside the village of Mbomo. Two broad forest types are present: forests of hydromorphic soils, and forests of terra firma. The forests of terra firma are the most extensive, and may be further subdivided into closed canopy forests and open forests. The forests of terra firma are generally quite heterogeneous in terms of species, although patches of Lophira alata-dominated forest exist. In Odzala, both forest types of terra firma are classed as Marantaceae forest. Republic of Congo , Mboko Concession, Odzala-Kokoua National Park, Department of Cuvette-Quest.
The name army ant (or legionary ant or marabunta) is applied to over 200 ant species, in different lineages, due to their aggressive predatory foraging groups, known as "raids", in which huge numbers of ants forage simultaneously over a certain area. Another shared feature is that, unlike most ant species, army ants do not construct permanent nests; an army ant colony moves almost incessantly over the time it exists Old World army ants are divided between the Aenictini and Dorylini tribes. Aenictini contains more than 50 species of army ants in the single genus, Aenictus. However, the Dorylini contain the genus Dorylus, the most aggressive group of driver ants; 60 species are known.
