Dromaius novaehollandiae (Latham, 1790)

This is the "Emu", native from Australia exclusively. His habitat includes savanna, light forests and cultivated fields: any places where the bird has the opportunity to run: this bird is unable to fly and must walk on the ground to find his food. Photography taken in the reserve from “Le Château de Sauvage” (Émancé, close to Chartres near Paris in France).

Brief description

The feathers are brown to grey-brown in most of the body. The throat is partly covered with feathers. The top is naked and covered with blue skin. The long legs are pinkish in colour. Iris is brown to red. The head is covered with black feathers. The beak is black. The eyes are red. The feathers are tousled giving his specific aspect to the bird.

IUCN status is “least Concern”, classified “not vulnerable”. The total population at the moment is around 700,000 individuals, not declining.

In the past, Emus have been considered as a nuisance by the Australian farmers. After the “First World War”, Australian army was committed to reduce the population of Emu. Unfortunately for the Australian Army, it was noticed a military success in favour of the birds: as the officers said, “the emu where having nothing to do with the live bullets of our machine guns” which were deployed for this battle. Today, the Emu are protected and hunting is strictly regulated.
