In spring, the Sonoran Desert of Arizona is full of activity. Look beneath the cacti, and you will find holes in the ground. So, what's in the hole? Join the animals, birds, insects, and reptiles to figure out the puzzle. Be curious! Learn the names of 29 critters in the languages of O'odham, science, Spanish, and English. Don Burgess took most of these wildlife portraits just north of Tucson, Arizona; and his daughter, Lisa Maria Burgess, wrote the book. Don Burgess (1939-2022) photographed most of the wildlife portraits in this book behind his house north of Tucson, Arizona; he photographed the burrowing owls near Cuauht�moc, Chihuahua. Also on the north side of Tucson, Bryan Wilson photographed the snake on the move and the tarantula, and Lisa Maria Burgess the bunnies in the hole. With thanks to Kristin Williams for photographing Don! And many thanks to Ronald Geronimo, Director of the Oʼodham Language Center, for providing names in O'odham, and to the staff at the Arizona-Sonora Desert Museum for their identification review.
