Once, when I was still a child, my father asked me:'Which weighs more: 1 kilo of iron or 1 kilo of feathers?'I remember that sure of myself I answered him quickly: 'Surely 1 kilo of iron weighs more, dad, because metal things, like the armor of medieval knights, are very heavy, while the feathers that decorate birds' wings are very light'.I can't tell you how disappointed I was when I heard him say:'No my son, that's wrong: they weigh the same, because 1 kilo is always 1 kilo!'Maybe because of the evening trick questions from my dad, when I grew up I decided to become a physicist, and to my big surprise I discovered that I was right when I was a child. Indeed: On the Earth, even if only by a little, 1 kilo of iron weighs more than 1 kilo of feathers!Don't worry, the sawdust that I have in my head has not caught on fire! But I hope that I have made you curious and that now you will want to come hunting with me for this strange and heavy mistake.

As heard on NPR's This American Life “Absorbing . . . Though it's non-fiction, The Feather Thief contains many of the elements of a classic thriller.” —Maureen Corrigan, NPR’s Fresh Air “One of the most peculiar and memorable true-crime books ever.” —Christian Science Monitor A rollicking true-crime adventure and a captivating journey into an underground world of fanatical fly-tiers and plume peddlers, for readers of The Stranger in the Woods, The Lost City of Z, and The Orchid Thief. On a cool June evening in 2009, after performing a concert at London's Royal Academy of Music, twenty-year-old American flautist Edwin Rist boarded a train for a suburban outpost of the British Museum of Natural History. Home to one of the largest ornithological collections in the world, the Tring museum was full of rare bird specimens whose gorgeous feathers were worth staggering amounts of money to the men who shared Edwin's obsession: the Victorian art of salmon fly-tying. Once inside the museum, the champion fly-tier grabbed hundreds of bird skins—some collected 150 years earlier by a contemporary of Darwin's, Alfred Russel Wallace, who'd risked everything to gather them—and escaped into the darkness. Two years later, Kirk Wallace Johnson was waist high in a river in northern New Mexico when his fly-fishing guide told him about the heist. He was soon consumed by the strange case of the feather thief. What would possess a person to steal dead birds? Had Edwin paid the price for his crime? What became of the missing skins? In his search for answers, Johnson was catapulted into a years-long, worldwide investigation. The gripping story of a bizarre and shocking crime, and one man's relentless pursuit of justice, The Feather Thief is also a fascinating exploration of obsession, and man's destructive instinct to harvest the beauty of nature.

The book will cover the entire range of the Painted Stork--beyond its stronghold in India and Sri Lanka to other countries--E Asia as well. For the sake of comparison, relevant information will be included about the other species of storks--both solitary as well as colonial, of Asia, as well as those in other parts of the world. Certainly plenty of references will be made about the work done on the American Wood Stork. Studies are underway in order to better understand the role of the monsoon rains on the nesting pattern of Painted Stork, besides attempting a review of the global status of the species. The former is likely to be of interest in augmenting our understanding about how global climate change is going to affect birds across India and the second is likely to raise interesting points about the distribution of species and their ranges. Both these studies will be carried through 2009 and should hopefully be included in the proposed book. Naturally, the focused interest in field research on the Painted Stork has resulted in accumulation of considerable information on this particular species, which is beyond the information contained on some standard Indian and international works and ornithological texts. The author hopes to include the entire spread of information of this species--from its systematics, evolution, distribution, ecology to its role in human culture as well as its association with mythologies. In other words, topics have not been restricted to the areas of the author’s research but have spilled over into areas of anthropology, ecology, conservation, etc.
