 Birds are among the most extensively studied of all animal groups. Hundreds of academic journals and thousands of scientists are devoted to bird research, while amateur enthusiasts (called birdwatchers or, more commonly, birders) probably number in the millions.
 
 Birds are categorised as a biological class, Aves. The earliest known species of this class is Archaeopteryx lithographica, from the Late Jurassic period. According to the most recent consensus, Aves and a sister group, the order Crocodilia, together form a group of unnamed rank, the Archosauria.
 
 Phylogenetically, Aves is usually defined as all descendants of the most recent common ancestor of modern birds (or of a specific modern bird species like Passer domesticus), and Archaeopteryx. Modern phylogenies place birds in the dinosaur clade Theropoda.
 
 Modern birds are divided into two superorders, the Paleognathae (mostly flightless birds like ostriches), and the wildly diverse Neognathae, containing all other birds.

On September 6, 2007, an African Grey parrot named Alex died prematurely at age thirty-one. His last words to his owner, Irene Pepperberg, were "You be good. I love you."

What would normally be a quiet, very private event was, in Alex's case, headline news. Over the thirty years they had worked together, Alex and Irene had become famous—two pioneers who opened an unprecedented window into the hidden yet vast world of animal minds. Alex's brain was the size of a shelled walnut, and when Irene and Alex first met, birds were not believed to possess any potential for language, consciousness, or anything remotely comparable to human intelligence. Yet, over the years, Alex proved many things. He could add. He could sound out words. He understood concepts like bigger, smaller, more, fewer, and none. He was capable of thought and intention. Together, Alex and Irene uncovered a startling reality: We live in a world populated by thinking, conscious creatures.

The fame that resulted was extraordinary. Yet there was a side to their relationship that never made the papers. They were emotionally connected to one another. They shared a deep bond far beyond science. Alex missed Irene when she was away. He was jealous when she paid attention to other parrots, or even people. He liked to show her who was boss. He loved to dance. He sometimes became bored by the repetition of his tests, and played jokes on her. Sometimes they sniped at each other. Yet nearly every day, they each said, "I love you."

Alex and Irene stayed together through thick and thin—despite sneers from experts, extraordinary financial sacrifices, and a nomadic existence from one univer­sity to another. The story of their thirty-year adventure is equally a landmark of scientific achievement and of an unforgettable human-animal bond.
