When the ship Victoria, the last remnant of Ferdinand Magellan's round-the-world voyage, returned to Seville in 1522, just 18 men survived from an expedition crew of more than 200. Magellan was not among them. Victoria held a fortune in spices — and the feathers of birds of paradise. The specimens' feet and wings had been removed, so people thought that the birds moved by divine means. Their shimmering plumage inspired wonder that galvanized both ornithologists and hunters.

“I must write about passions for birds that have dark, even fatal undercurrents.”

Magellan's voyage, recounted in Bernd Brunner's Birdmania, is one manifestation among multitudes of humanity's great obsession with birds. By the end of 2016, one-third of a million people had contributed more than one-third of a billion observations to eBird (http://ebird.org), the world's largest citizen-science project. We know the natural history and distribution of birds much better than those of any other group. And colourful people walk the paths to this knowledge, as is amply shown in both Birdmania and Noah Strycker's Birding Without Borders. On a hike in Colombia, I contemplated these books — and concluded that I must write about passions for birds that have dark, even fatal, undercurrents.

In Brunner's tour of bird devotees through history, we meet a cast including thirteenth-century Holy Roman Emperor Friedrich II von Hohenstaufen, who authored a treatise on falconry, and twentieth-century US ornithologist Robert Porter Allen, who did much to protect the whooping crane (Grus americana). Brunner reveals how hummingbirds were admired by European travellers long before becoming a highlight of Victorian specimen cabinets. Although most species of these acrobatic wonders live in the remote Andes and Amazon, the drive to find new ones was intense. Only 34 were known by 1788, but by 1900, taxonomists had described 312 of the current 336. Avid collector John Gould recorded most of them in his lavishly illustrated Monograph of the Trochilidae, or Family of Hummingbirds (1849–61). The ranges of some hummingbirds are still being uncovered.

The end of this golden age of discovery was marked by a controversial figure: Richard Meinertzhagen, chair of the British Ornithologists' Club. A career army officer, he participated in military exploits such as Edmund Allenby's 1917 victory in the Middle East. He was also an explorer, touring Afghanistan in 1937 with a young Salim Ali, destined to become India's most distinguished ornithologist. There, Meinertzhagen described a new species of snowfinch (Montifringilla theresae), the existence of which I can confirm: mentored by Salim Ali, I ringed some on an expedition in 1970. But Meinertzhagen was a monumental fraud. He stole specimens, mislabelled them and added false locations. As Brunner relates, Meinertzhagen's wife, ornithologist Ann Jackson, died in suspicious circumstances.

In Birding without Borders, Strycker records his quest to see as many species as possible in a year: what's known as a “big year”. That comes with bragging rights, but demands money and time. Some of the more than 10,000 known bird species have large geographical ranges, so there are many places to see them. Yet 5,000 have ranges smaller than the median of 280,000 square kilometres. Fortunately, these are geographically concentrated (see www.biodiversitymapping.org). So a big year is mostly a matter of traversing the tropics: Central America, the northern Andes, coastal Brazil, West Africa, the East African mountains, Madagascar, northeast India, the islands of southeast Asia, New Guinea and Queensland, Australia. Strycker also visits other places, often lamenting that he doesn't see enough species to keep up his total.

His epic mission is made possible by a global network of guides. They drive him to forests and play tapes of the bird's song. Hopefully the bird responds or, better, pops out to see what's going on. Hummingbirds are lured to sugar-water feeders. My favourite, the small, upright antpittas, feed mainly on forest floors; they are hard to see, but some have been trained to emerge and feed on worms.

Strycker finds 6,042 species, beating the previous record — and does so travelling with a very restricted wardrobe. (When I asked one of his Colombian guides what he thought of Strycker, he answered, “Smelly.”) In my view, however, visiting well-trodden paths with the same guides, and playing the same recordings to lure the same birds, may harm individual birds. And it does not contribute anything new to our knowledge of their distributions. I cherish half a century of birding solitude with binoculars, a notebook and, in places such as Afghanistan, not even a bird book.

Colombia tops the global league with most bird species, and most species seen in one day. Its growing birding community penetrates remote areas and pieces together which species aren't being seen. That provides invaluable data for conservation. And along the dirt track to Buenaventura, in a cloud-forest shack perched precariously on an Andean hillside, works Doña Dora. She serves bananas and papayas to a dozen species of brightly coloured tanagers, and massive lunches of soup and empanadas to birders. Here, and in a thousand similar places worldwide, the bright side of bird watching is providing income to poor, rural communities and incentives to protect remaining ecosystems.
