Massive landslide in Italy

Gravity is the primary driving force for a landslide to occur, but there are other factors affecting slope stability that produce specific conditions that make a slope prone to failure. In many cases, the landslide is triggered by a specific event (such as a heavy rainfall, an earthquake, a slope cut to build a road, and many others), although this is not always identifiable.

Landslides are frequently made worse by human development (such as urban sprawl) and resource exploitation (such as mining and deforestation). Land degradation frequently leads to less stabilization of soil by vegetation.

Additionally, global warming caused by climate change and other human impact on the environment, can increase the frequency of natural events (such as extreme weather) which trigger landslides

A thirsty black wolf

A black wolf is a melanistic colour variant of the gray wolf (Canis lupus). Black specimens were recorded among red wolves (Canis rufus), though the colour morph in this species is probably now extinct.

Genetic research from the Stanford University School of Medicine and the University of California, Los Angeles revealed that wolves with black pelts owe their distinctive coloration to a mutation which occurred in domestic dogs, and was carried to wolves through wolf-dog hybridization.

Besides coat and knee colour, they are normal grey wolves.

Secretary bird (Sagittarius serpentarius)

Unlike most birds of prey, the secretarybird is largely terrestrial, hunting its prey on foot. Adults hunt in pairs and sometimes as loose familial flocks, stalking through the habitat with long strides.

Prey may consist of insects such as locusts, other grasshoppers, wasps, and beetles, ot small vertebrates like rodents, frogs, lizards, small tortoises, and birds such as warblers, larks, doves, small hornbills, and domestic chickens.

They occasionally prey on larger mammals such as hedgehogs, mongooses, small felids such as cheetah cubs, striped polecats, young gazelles, and both young and full-grown hares.
