    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.

    (That's why it's been Employee of the Month for 4.5 billion years.) So why does the Sun get to be the center of attention? Because it's our solar system's very own star! This funny and factual picture book from Awkward Yeti creator Nick Seluk explains every part of the Sun's big job: keeping our solar system together, giving Earth day and night, keeping us warm, and more. In fact, the Sun does so much for us that we wouldn't be alive without it. That's kind of a big deal. Each spread features bite-sized text and comic-style art with sidebars sprinkled throughout. Anthropomorphized planets (and Pluto) chime in with commentary as readers learn about the Sun. For instance, Mars found someone's rover. Earth wants the Sun to do more stuff for it. And Jupiter just wants the Sun's autograph. Funny, smart, and accessible, The Sun Is Kind of a Big Deal is a must-have!
