White Ibises Have an Instinct for Stealing Food
White ibises practice kleptoparasitism, stealing food from humans, parent birds, and sometimes even chicks.
[FamTimes reporter Jennylyn Gianan] The white ibis (Eudocimus albus), commonly found in coastal areas of the southeastern United States, Mexico, and northern South America, is a lanky bird with orange legs and a long, downward-curving bill.
They are skilled at catching and eating small fish and insects.
However, these birds have recently evolved through constant interaction with humans, who have begun encroaching on their habitats.
Specifically, they have developed a habit of stealing human food.
Scientifically known as kleptoparasitism, this improper behavior is actually a common tactic employed by various animals.
They survive by stealing food not only from humans but also from other animals.
Adult males usually take on the role of the “food thief.”
They approach parent birds preparing to feed their young.
The moment a mother bird opens her bill to feed her chick, the food thief inserts its own bill into her throat and steals the food.
These thieving ibises sometimes even attack chicks to take their food.
Therefore, if you spot a white bird circling overhead as you are about to eat a hamburger, be careful to avoid being attacked.
