The Amazing Lives of Birds
Book Review: Beaks, Bones, and Bird Song, by Roger J. Lederer
If you are interested in birds but don’t have much of a science background, this book is a fun and fascinating read. The author establishes first that birds face daunting odds in their struggle to survive and reproduce. Only about 10% of songbirds make it from egg to adulthood, and about half of all adults perish every year.
In response to this harsh challenge, birds have developed an amazing array of survival strategies. Lederer has chapters on feeding, sensory abilities, flight, migration, and surviving difficult weather conditions. He closes with a grim but ultimately hopeful discussion of how birds are affected by human activity.
To give you a taste of this book, let me share eight fascinating facts that I learned from Beaks, Bones, and Bird Song.
- Starlings incorporate certain fragrant plants into their nests to keep them healthier.
- Birds can eat even the hottest peppers because they lack the chemical receptor that responds to capsaicin.
- Birds are able to use the earth’s magnetic lines of force to navigate.
- An African bird called the honeyguide has learned to lead people to bee colonies. The people take the honey and the birds eat the eggs and larvae.
- Parrots eat clay, which binds with the poisons of toxic seeds, rendering the seeds harmless.
- The western screech owl keeps live snakes in its nest as a means to controlling maggots and other pests.
- Vultures poop on their own legs to keep them cool and limit infections.
- And speaking of poop, Canada geese poop about every 20 minutes. OK, so maybe that’s not so fascinating, but it does make sense to anyone who has ever dealt with a field infested with Canada geese.
And a couple more facts of interest to people with bird feeders. First, don’t worry about what happens if you go on vacation and leave the feeders empty for a few weeks. Studies show no difference in bird mortality.
Also, feeders don’t make birds any more vulnerable to predators than they would be elsewhere in the wild. In fact, they may even be safer because birds in large groups are likely to detect predators more quickly.
Overall, Beaks, Bones, and Bird Song is an absorbing and entertaining read for the layperson with a soft spot for feathered creatures.
