I am a pretty avid reader, and as you might guess, I spend a lot of time reading about birds. I decided that I wanted to share these books with you. So today is the first BirdNation book review. If you read this blog I assume that you have an interest in birds, so I thought you may find some worthwhile reading material through this feature.
I just finished reading The Most Perfect Thing: Inside (and Outside) a Bird’s Egg by Tim Birkhead. Tim Birkhead is a British zoologist and works at the University of Sheffield as a professor of behavior and evolution. He has written numerous book about birds and their behaviors, including the popular Bird Sense in 2012. In this book, Tim Birkhead takes you on a journey of how the egg is developed. The journey begins in late 19th century England with oologist (a scientist who studies bird eggs) George Lupton. George Lupton had an extensive collection of Common Guillemot eggs, which are now in the Natural History Museum in Tring, Hertfordshire, England. Birkhead refers to George Lupton and Common Guillemots as his prime example throughout the text. Along the way we learn about other scientists who made contributions to bird biology and egg production, as well as learn about the eggs of numerous bird species.
Birkhead starts with the outside of the egg and work his way in. The first few chapters talk about the structure and physical appearance: egg shape, shell thickness, and color. There are two chapters concerning color. Birkhead first talks about how eggs become the colors they do and then talks about why.
The middle chapters of the book are about what happens inside the egg and focus on the albumen and the yolk. The albumen, also know as the “egg white”, forms around the yolk. It provides nutrients for the embryo and protects the yolk. The albumen is mainly 90% water and 10% proteins. The egg yolk is the primary food supply for the embryo. Birkhead goes into detail about these subjects and there are detailed diagrams throughout the book to help the readers visualize these features.
The final sections of the book are all about laying, incubating, and hatching. Topics explored include how the egg leaves the oviduct (where eggs travel from the ovaries to outside the body), incubation lengths of different species, and the process of how the chick leaves the egg (which is not as quick as you would think!).
The Most Perfect Thing is a fascinating book. Although everyone is familiar with eggs, many people don’t know about the process of egg formation and hatching, so it’s an eye-opening and amazing process to learn about. I would recommend this book to anyone who is interesting in learning about the science behind eggs. It is not a leisurely read, however. Besides the history portions about Lupton and other scientists/studies, most of this book reads like a text book. One thing I like about Tim Birkhead is his ability to make these scientific studies accessible and easy to understand to casual readers as well as more science-minded individuals. Even if you are a casual reader, I recommend this book if you are into learn about bird biology and want to know more the science of eggs. There are so many amazing thing to learn through this book. I’m sure by the end you’ll agree that the bird egg is as close as you can come to The Most Perfect Thing.
