Bubulcus ibis (Cattle Egret)

Synonyms: Bubulcus ibis ibis
Language: French; Spanish

Invasive Species

Bubulcus ibis are small stocky herons that associate with grazing species of mammals both domestic and wild. They have strong migratory instincts and disperse thousands of miles in the direction of their choosing. They are, for the most part, self-introduced. They have been observed 'feeding on' native species of birds. They are known to host ticks that could introduce and spread certain tick-borne diseases.
