Much wasteful spending is happening on America's college campuses.

Here are 10 outrageous examples of university studies funded by taxpayer dollars obtained by Campus Reform:

1. Gambling for Pigeons 

The National Institute of Health (NIH) granted $465,339 to researchers at Reed College in Portland, Oregon to "create a token-based economy where pigeons are taught to gamble with slot machines."  

The study gave pigeons tokens that they can "earn, accumulate, spend, or gamble" on slot machines, the New York Post reports. 

2. Chimps Throwing Feces

The US National Institutes of Health spent $592,527 at Emory University in Atlanta to explore why chimpanzees throw feces. Another $117,000 was necessary to conclude that most chimps are right-handed, the Washington Examiner reports. 

Their research suggests that throwing feces is a sign of intelligence in chimps. 

3. Drunken Finches

The National Institutes of Health gave $5 million to the Oregon Health & Science University to study if finches slurred their songs when alcohol was in their systems. 

The birds were given white grape juice spiked with alcohol, which impacted their singing ability, NBC News reports. 

4. Bees on Cocaine

The National Institutes of Health funded over $240,000 to study the impact of cocaine on honey bees at the University of Illinois at Urbana-Champaign. 

With cocaine in their system, the bees were more likely to dance, the researcher found.
