Cattle Egret

The Cattle Egret is a small, compact, thick-necked egret notably different in shape and behavior from other white egrets, favoring dry grasslands and pastures over wetlands. Outside the breeding season it is mostly white with a stout yellow or orange bill, while during the breeding season adults develop striking buff-orange plumes on the crown, breast, and back, along with a reddish bill and legs.

Unlike most herons, which hunt in or near water, the Cattle Egret has adapted to forage on dry land in close association with grazing animals, walking alongside cattle, horses, and other large herbivores to catch insects disturbed by their movement. The species underwent a spectacular natural range expansion in the 20th century, spreading from Africa to the Americas, Australia, and beyond largely on its own.

Key field marks

• Stocky build with a short, thick neck, unlike the slender build of other egrets
• Stout yellow or orange bill (reddish in breeding adults)
• Buff-orange plumes on crown, breast, and back during breeding season
• Frequently seen walking beside grazing livestock in dry fields

Similar species

• Snowy Egret and Little Egret: both slimmer and longer-necked with black bills, and typically found near water rather than dry pastures
• Great Egret: much larger and more slender with a longer neck

The short, thick neck, stocky posture, and habit of foraging in dry fields alongside livestock readily distinguish the Cattle Egret from other white egrets.

Range and habitat

Originally native to Africa and parts of Asia, the Cattle Egret has expanded dramatically and now occurs on every continent except Antarctica, inhabiting grasslands, pastures, farmland, and, less often, wetland edges, typically favoring open dry habitats over deep water.

Migration

The species is highly mobile and capable of long-distance dispersal, which drove its rapid natural colonization of the Americas beginning in the late 19th and early 20th centuries; many populations undertake seasonal movements tied to weather and food availability rather than fixed long migrations.

Behavior

Cattle Egrets are highly social, often foraging and roosting in large flocks, and are well known for their close association with grazing livestock and, increasingly, agricultural machinery, following animals or machines to catch insects and small animals flushed from the grass.

Voice

Calls include a variety of harsh croaks and cackles, typically given at breeding colonies rather than while foraging.

Feeding

They feed mainly on insects, especially grasshoppers and crickets, disturbed by the movement of grazing animals, and also take other invertebrates, frogs, and occasionally small rodents.

Nesting and breeding

Cattle Egrets nest colonially, often in large mixed colonies with other herons and egrets, building stick nests in trees or shrubs; both parents incubate the typically three to four pale blue eggs.
