Respect the animal kingdom

Dolphins can follow complex instructions.

Orangutans can learn complex tasks, such as washing clothes by hand, after just a few tries.

And even pigeons can recognize, count, or name different objects.

Dr. Irene Pepperberg of the University of Arizona has been studying Alex and several other African Greys, parrots that are remarkable mimics.

Alex can name more than 40 objects and understands the concepts of "same" and "different," "absence," "quantity," and "size."
