Leafcutter Ants

Leafcutter Ants are any of the forty seven species of ants belonging to the genera Atta and Acromyrmex that chew leaves. They are tropical ants that grow fungi that inhabit the southern United States, Central America and South America. The crops are grown in underground gardens that can be enormous. The cultivated fungus is completely dependent on the care of the ant and is the food of all the members of the colony, being the only food of the queen, the larvae and other members of the colony that remain in the nest; what turns the relationship into an obligated mutualism. The workers who cut leaves, in addition, ingest sap from the plants while cutting their segments.

The cutters go up in mass to the trees and they kneel their jaws on the leaves and cut sections. The columns of haulers can be seen with large pieces of vegetation raised high. They can attack many plants but constantly change the plant, apparently preventing the total removal of leaves and the death of trees, thus avoi…

Black Hawk-Eagle (Spizaetus tyrannus)

The Black Hawk-Eagle (Spizaetus tyrannus) is a large, black raptor of Neotropical forests. Its preferred habitats include humid and moist forests close to rivers, and several types of Woodland, and is found from central Mexico to eastern Peru, the south of Brazil, and far northern Argentina. They prefer semi-open areas, second growth forests, river areas and forest ridges, but have also been found in extensive forests.

Individuals often soar high overhead, where they attract attention with sharp, whistled calls. They feed on mammals, birds, and reptiles, taken largely from trees and detected from a perch. Though light and small compared to other eagles, this bird is a powerful predator that frequently hunts relatively large prey. It mainly eats large rodents, opossums and monkeys, as well as, occasionally, bats and birds, including large birds such as toucans, and chachalacas, and snakes and lizards. 



It exhibits a conspicuous crest on the crown, of black feathers with white bases.
