Vegetarian Birds Turn Carnivorous | IFLScience

Ornithologists are puzzling over the case of a vegetarian bird that has developed an unprecedented taste for meat. So far, the birds haven’t shown any sign of including live animals, let alone humans, in their diet. However, a brightly colored version of “The Birds” may be just around the corner.

Rainbow lorikeets (Trichoglossus moluccanus) are a species of parrot common along the east coast of Australia. Although they have become pests after being introduced into Western Australia and New Zealand, in their native regions their bright colors make them exceptionally popular and it is not uncommon for Australians to leave food and water out in the hope of attracting them to their gardens.

This is what an individual named only as Bill was doing on his property at Elimbah, north of Brisbane: He was leaving out seeds for the lorikeets and king parrots that inhabit the nearby forests. However, Bill doesn’t discriminate by color and also provided minced meat for the magpies, currawongs and kookaburras that also live in the area.

Around seven years ago, Bill noticed that the lorikeets were eating the meat intended for their monochrome counterparts. “At first they went for the seed but then they started chasing the other birds away from the meat, which surprised me,” he told the ABC.

Eventually, Bill reported the behavior to Professor Darryl Jones of Griffith University who was astonished. “I have researched what birds feed on all around the world,” Jones told the ABC. “To see a lorikeet eating meat astonishes me completely. I have never heard of such a thing before.”

Ironically, however, the meat might still be healthier than the sugar-rich treats many people ignorantly offer.

Although many vegetarian animals are known to engage in a little scavenging when short of protein or calcium, this behavior is quite exceptional. The lorikeets are superbly adapted to feeding on nectar, with a truly bizarre tongue evolved for the purpose.

The occasional meaty snack is one thing, but putting in the energy to scare off larger birds requires a serious taste for a food their ancestors haven’t been digesting for millions of years. “It makes no sense at all,” Jones said. Even carnivorous birds can develop fatty liver disease from the minced meat of sedentary farm animals. It’s also unclear why species such as Australian magpies, known for striking fear into cyclists, are letting the lorikeets chase them away from their preferred food; presumably the kookaburras were too busy laughing at the lorikeets’ clown suits to take them on.

Eating unusual foods can be a sign of malnourishment or ecological displacement, but as Jones noted, “The birds look extremely healthy in those pictures.”
