Endangered species

As the author of this engaging book makes plain, it is with good reason that owls are such cherished birds. They possess the most acute sense of hearing not just of any avian group but possibly of any creature. In experimental conditions of total darkness, barn owls were able to catch mice merely by hearing their rustling as they moved. The owls’ own flight is soundless because of special comb-like structures on the leading edges of their wings. Almost all owl species are adapted to see acutely at night and the largest are able to catch deer or pluck young eagles from the nest. But it is not merely these definable physical attributes that set owls apart. They also have a psychological aura. Their forward-facing eyes in a rather flat-faced configuration mimic our own arrangement.

Nathalia Holt’s book begins irresistibly. The year is 1928. Two sons of Theodore Roosevelt called Ted and Kermit – yes I know we’re thinking it’s a Wes Anderson movie – have smoothed a map out on the table in front of them. Let’s imagine the setting is a bit like the Explorers’ Club in New York, with exotic anthropological curios on the walls – poisoned spears and wooden shields – and globes the size of beach balls lit up from within. The land they are examining is mainly coloured in greens, browns and greys. But running across the map, like the stripes of a tiger, are irregular white blotches. Each of these blank spaces represents terra incognita. This is China, or what was then known of it.
