NAME: ‘Cattle’ in the name relates to the bird’s habits.  ‘Egret’ comes from French ‘aigrette’, which refers to the bird’s feathers used as ornaments in the past. Latin genus name ‘Bubulcus’ means ‘concerning cattle’. Latin species name ‘Ibis’ comes from ancient Egyptian ‘ibis’. Applied in error by Carl Linnaeus, as this bird is part of the Heron family, not the Ibis.
HABITAT: ‘Traditionally’, i.e. in natural settings, cattle egrets accompany cattle feeding on insects and other small animals, and will rid cattle of the pests that plague them, such as ticks and flies. For this reason farmers appreciate them. Their adapting to human environments makes their presence now seen in city parks and also around airports.
DIET: Insects, arthropods, small reptiles, bird eggs/nestlings, some fish, also garbage.
NESTING: Nest in colonies in treetops near marshlands and coastal habitats, sometimes mixing with other species of herons. Three to seven light blue eggs are laid, incubated by both parents. Chicks fed by both parents.
DISTRIBUTION: Native to Africa, Europe, and parts of Asia, introduced in many countries including Hawaii in the USA. Also expanding range on its own.
