    Because she was going to study him, she decided to call him Alex--short for Avian Learning EXperiment. At that time, most scientists thought that the bigger the brain, the smarter the creature; they studied great apes and dolphins. African greys, with their walnut-sized "birdbrains," were pretty much ignored--until Alex. His intelligence surprised everyone, including Irene. He learned to count, add, and subtract; to recognize shapes, sizes, and colors; and to speak, and understand, hundreds of words. These were things no other animal could do. Alex wasn't supposed to have the brainpower to do them, either. But he did them anyway.Accompanied by Meilo So's stunning illustrations, Alex and Irene's story is one of groundbreaking discoveries about animal intelligence, hard work, and the loving bonds of a unique friendship.

But the staff at the zoo knew they could save her.  It would take creative thinking and teamwork. They would have to study the makeup of hippo milk for the first time ever and reach out to medical colleagues, including a team at the local Children's Hospital with superior vein-finding skills,  to ensure that Fiona would begin to gain weight and become healthy. When Fiona began to thrive, her star began to rise, and soon she became an internet sensation, her picture and videos garnering thousands and thousands of likes and fans on Instagram and Facebook.  Now a Fiona appearance at the Zoo mimics a Beatles concert.  What made this little, now big, hippo such a big hit with people all over the world?  And what's in store for her and her family in the future?
