"Author/illustrator Matt Sewell has created a lovely book for the budding ornithologist. Divided into sections by continent, the volume includes lesser-known bird species. Each entry includes a charming, somewhat cartoon-like watercolor painting of the bird and several informational paragraphs."

"If you have a budding ornithologist in the family, they will be awed by Matt Sewell's gorgeous compendium of more than 150 birds from around the world. Sewell knows just how to entice young readers with engaging, humorous, and insightful text that provides a robust and individual introduction to each bird as well as their status in the world. Every entry is accompanied by brilliant watercolors that highlight each species' spectacular, surprising, and sometimes even seemingly Dr. Seussian plumage." - Celebrate Picture Books

"Tackling an entire class of animals is a daunting task, but this book, neatly organized by continent, rises to the challenge. Each section has a map and a small index of species. There is a short entry with a full-color illustration for each species. Useful for projects, entries include the animals' scientific species name and details such as size, diet, behavior, and how their environment is impacted by humans. Overall, a very readable and beautiful book. A charming compendium on the world's birds."
