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 :-) [0] https://www.amazon.com/Are-Smart-Enough-Know-Animals/dp/0393353664/ https://www.amazon.com/Are-Smart-Enough-Know-Animals/dp/0393...
