Identification
Present on every continent, very common in Africa, the Western Cattle Egret is a medium-sized wading bird. He often accompanies livestock in fields, which explains his name. It differs from other herons in its particular silhouette, at rest with the head and neck tucked into the shoulders.
This heron is slightly smaller than the Little Egret. It is known in two relatively different plumages. In nuptial plumage, it bears orange elongated feathers on the head, neck, chest and lower back. Its beak is bright orange and its legs are pink. The iris is yellow. In interstitial and juvenile plumage, it is entirely white with dark legs. Its beak is orange.

Voice song and cries
Habitat
Unlike other herons, the Western Cattle Egret is not mainly associated with the aquatic environment. Although water and wetland areas continue to play an important role in its lifestyle, it is most often found in grassy steppes, meadows, crops, and even in artificial environments such as sports fields or urban lawns.
Behaviour character trait
This bird displays a highly developed gregarious instinct. It is almost always observed in groups. It nests in often densely populated wooded areas.
Flight
Typical flight of the Western Cattle Egret, with the neck folded and legs stretched backwards. The flight can be acrobatic when the bird drops towards the ground in zigzagging.
Dietfeeding habits
As a terrestrial predator, the Western Cattle Egret has a mainly insectivorous diet. It is often found in the company of livestock on which it perches. It takes advantage of the disturbance caused by cattle or agricultural machinery to capture insects and other arthropods, various other invertebrates as well as small vertebrates such as mice and shrews. It occasionally hunts with its feet in the water and fish can then enter its diet.
Reproduction nesting
Nesting is a business for both parents, but there is a fairly rigorous division of tasks: The female is in charge of construction itself, while the male is responsible for collecting the materials.
When one of the partners returns to the nest, the couple adopts a ceremonial attitude with the back feathers erect and the head feathers flattened.
The female lays 4 to 5 bluish-green eggs that are alternately incubated by the male and female for 22 to 26 days. The young are nidicolous and fly away in about 30 days, but they are able to climb in the neighboring branches of the nest at the age of 2 to 3 weeks.
