Researchers capture video of freshwater fish grabbing birds out of the air

Jan 13, 2014 by Bob Yirka report

(Phys.org) —A team of researchers with North-West University in Potchefstroom, South Africa has for the first time captured on video, a freshwater fish leaping out of the water and into the air to grab a flying bird. The video was part of research the team was conducting on tigerfish in African lakes—their paper has been published in Journal of Fish Biology.

Many , including fish, have been seen grabbing , but in almost all instances, the birds are nabbed as they are sitting on the water or on shore near the water. In this new study, the researchers found that the tigerfish were able to use two different tactics to grab barn swallows—birds that are generally known for their inflight speed and agility. The tigerfish, which have large sharp teeth were observed leaping and catching birds while swimming just near the surface, and also when pushing up from deeper water. The video of one of the fish actually catching a bird was filmed near Schroda Dam, which has formed a lake on the Limpopo River—part of the Mapungubwe National Park in South Africa.

The team reports that they were skeptical of rumors about fish leaping out of the water to catch birds, and were merely looking to study the habitat and migration habits of tigerfish. They were all shocked, the team reports, when they saw the first incident. After studying the tigerfish for some time, they observed on average 20 instances a day of the fish leaping out of the water and successfully grabbing birds, which were pulled under the water and eaten. They found that the fish were able to leap as far as three feet out of the .

Tigerfish are well-known in Africa—they're a prized game fish and are notoriously fierce predators. For years, there have been anecdotal reports of fish grabbing birds out of the air over lakes in Africa, but until now, no one has documented them doing so. The video unequivocally proves that the fish are able to catch birds in flight and the observations by the researchers indicate that it is a common occurrence. The researchers suggest that the tigerfish's abilities have gone unnoticed by scientists until now because so little research has been conducted on freshwater in Africa.

That's pretty impressive.

I've seen and heard of Catfish in a pond swallowing ducklings which were on the water. I don't know whether anyone I've known would have seen a fish jump out of the water to intercept and eat a flying bird.

It would be an interesting experiment to see if that happens. Maybe dangle a duckling over a pond a few inches to a foot above the water, and see if a large mouth bass or a catfish will jump out of the water to catch it.

Ya ain't seen nuthin'..
We have big mouth carp.......nawww, not the tea party nazis...... grabbing folks out of boats on the Mississippi River and trying to eat them. And we have barge operators trying to buy politicians so they can open the Great Lakes to them. Once those monsters are in the Great Lakes, then no one will care about environmental regs there to protect the fish...ALL THE GAME FISH WILL BE GONE. So then the barge operators and everyone else will be able to freely pollute, and the Chinese will then be able to buy great lakes water cheap. With their own carp in it, they will feel right at home.

Job Application:
Field Technician - Duck Handler
Maintain average distance between duckling and surface of water of no more than four inches over long periods of time and record sightings of catfish attempting to eat said duckling. Replace ducklings as necessary.
