If you liked this article, you might enjoy the book "Are we smart enough to know how smart animals are?" by Frans de Waal [0]. He does a great job of describing all kinds of surprisingly intelligent animal behaviors, and some very clever tests to decide how and when they apply.

Interestingly, about 30% or so of the book is kind of a rant against other animal behaviorists who have an "animals are stupid, and no amount of proof to the contrary will shake that belief" attitude. But that yields some pretty entertaining stories (and interesting experiments) as well :-)

a great read -- almost as good as Franz de Waal's "Are We Smart Enough to Know How Smart Animals Are?" (where this study and others are cited) https://www.amazon.com/Are-Smart-Enough-Know-Animals/dp/1783... .
There is an interesting popular book on Ethology by Frans De Waal.

Here is a great review of this book http://www.theatlantic.com/magazine/archive/2016/05/how-anim...

the passage that got me hooked: “a better way to think about other creatures would be to ask ourselves how different species have developed different kinds of minds to solve different adaptive problems. Children and chimps and crows and octopuses are ultimately so interesting not because they are mini-mes, but because they are aliens—not because they are smart like us, but because they are smart in ways we haven’t even considered"

for example different species have different approaches to problem solving: Chimpanzees try to comprehend/model a problem while Monkeys are solving tool building problems by trial and error (that's from the book)
