''Austerlitz'' contains fascinating asides about such disparate matters as military fortifications, capitalist architecture and the secret lives of moths; a charming tale about a boy's homing pigeon, who walks home with a broken wing, and a short history of the land on which the Liverpool Street Station was built in London.

A few years back, Marty entered a three-hundred-mile race. She didn't return home. Her human companion, Orlando, assumed she had been killed. But, two weeks after the race, Orlando found Marty on his porch. She had a broken wing; she had apparently walked home.
Marty was a homing pigeon, one of dozens of breeds of the ubiquitous species of pigeon. Most of us are accustomed to seeing rock doves, one breed, almost everywhere we travel. In Pigeons: The Fascinating Saga of the World's Most Revered and Reviled Bird, author Andrew D. Blechman explains these birds’ histories and uses and centuries of human obsession with them. The birds apparently inspire great love or great hatred and little in between.
Victory is mine!
