Follow the flight of the blackpoll warbler

Diversity is a mark of richness and environmental health - and birds are its flag-bearers.

Bird variation set both Charles Darwin and Alfred Russel Wallace on the path to discovering natural selection and its role in evolution. Wallace observed it on the Molucca Islands, Darwin on the Galapagos. Diversity is a mark of richness and environmental health and birds are its flag-bearers. Their disappearance, like the collapse of the canary in the mine, is our warning signal.

Yesterday, wondering where blue tits and great tits have gone this summer (am I providing the wrong kind of peanuts?), I found the Shakespearean phrase “nature’s riches” used for a site explaining the rich geological pickings of the Arctic, now being unlocked by global warming. It could equally refer to the tropical forests being destroyed to make monocultures such as palm oil. Maybe only migrating birds know (though it must be a special kind of “knowing”) the true force of the paradox that areas of greatest biodiversity are also areas of greatest conflict – and how fast biodiversity is being lost in our time.

This is true above all between Arctic and tropic. These words first occur in the late 14th century. In Greek, arktikos means “belonging to bears”. Not polar bears: people knew the night sky and the constellation of the Great Bear. Tropic, from the Latin tropicus and the Greek trope, meaning “turn”, refers to the daytime sky where the sun, after reaching its northernmost or southernmost point, stands still (solstitium) and turns back.

If all birds stayed in the tropics, many would die out through competition for food and nesting sites, so species evolved to migrate. As resources regenerate each spring in the north, millions of birds trade tropic for Arctic: less competition for insects, longer daylight hours to find them. When Arctic food dwindles in autumn, they return to the replenished tropics.

These journeys are risky but better than the alternative. Blackpoll warblers winter in Venezuela, then fly north in spring over the Gulf of Mexico up to Alaska, where they build little cup nests in fir trees. They take a different route back: they fly south-east over the Great Lakes and from the New England coast some follow the shoreline down to Florida, some island-hop to South America, but most fly east to pick up winds hurling them over the Caribbean non-stop, day and night, for 88 hours to Venezuela. Four days over the Atlantic in peak hurricane season, facing spiralling winds, clouds, rain. Many crash exhausted in the sea. Yet it’s worth the risk because this route is 1,500 miles shorter and survivors establish a winter feeding territory earlier.

Nature is prodigal, said Darwin. So much waste. “The face of nature may be compared to a yielding surface, with 10,000 sharp wedges packed closely together and driven inwards by incessant blows, sometimes one wedge being struck, and then another with greater force.”

His understanding of the conflict driving nature’s apparent harmony was triggered by reading “An Essay on the Principle of Population” by Robert Malthus. This led him to the concept of natural selection and also to ideas about the evolution of instincts and human psychology.He was young: after South America, his mind was racing. “The principle of population is strife”; “All forms compete against others”; “You can understand the true conditions of life only if you use your imagination to hold on to a sense of the ruthlessness of the natural forces that could waste the bright surface.”

This side of his work inspired Freud’s insight into psychic conflict and the origins of human aggression. “The human mind is shaped by its animal past,” said Darwin. Nature’s ruthlessness is ours, too: our bodies, our psyches.

Unlike a blackpoll warbler, we can’t fly away when resources are gone. In our time, it seems, Arctic and tropic will change their meanings again. But biodiversity may no longer be part of the equation.

If the SNP truly want another referendum, the clock is ticking

At party conference in Glasgow, I heard Scotland’s governing party demand a future distinctly different from the one being sketched out in Westminster. 

Nicola Sturgeon described Glasgow as the “dear green city” in her opening address to the SNP party conference, which may surprise anyone raised on a diet of Ken Loach films. In fact, if you’re a fan of faded grandeur and nostalgic parks, there are few places to beat it. My morning walk to conference took me past chipped sandstone tenements, over a bridge across the mysterious, twisting River Kelvin, and through a long avenue of autumnal trees in Kelvingrove Park. In the evenings, the skyline bristled with Victorian Gothic university buildings and church spires, and the hipster bars turned on their lights.

In between these two walks, I heard Scotland’s governing party demand a future distinctly different from the one being sketched out in Westminster. Glasgow’s claim to being the UK’s second city expired long ago but I wonder if, post-Brexit, there might be a case for reviving it.



Scottish politics may never have looked more interesting, but at least one Glasgow taxi driver is already over it. All he hears in the back of his cab is “politics, fitba and religion”, he complained when he picked me up from the station. The message didn’t seem to have reached SNP delegates at the conference centre on the Clyde, who cheered any mention of another referendum.

The First Minister, though, seems to have sensed the nation’s weariness. Support for independence has fallen from 47 per cent in June (Survation) to 39 per cent in October (BMG Research). Sturgeon made headlines with the announcement of a draft referendum bill, but read her speeches carefully and nothing is off the table. SNP politicians made the same demands again and again – devolved control of immigration and access to the single market. None ruled out these happening while remaining in the UK.

If Sturgeon does want a soft Brexit deal, though, she must secure it fast. Most experts agree that it would be far easier for an independent Scotland to inherit Britain’s EU membership than for it to reapply. Once Article 50 is triggered, the SNP will be in a race against the clock.


The hare and the tortoise

If anyone is still in doubt about the SNP’s position, look who won the deputy leadership race. Angus Robertson, the gradualist leader of the party in the Commons, saw off a referendum-minded challenger, Tommy Sheppard, with 52.5 per cent of the vote.

Conference would be nothing without an independence rally, and on the final day supporters gathered for one outside. A stall sold “Indyref 2” T-shirts but the grass-roots members I spoke to were patient, at least for now. William Prowse, resplendent in a kilt and a waistcoat covered in pro-indy
badges, remains supportive of Sturgeon. “The reason she has not called an Indy 2 vote
is we need to have the right numbers,” he told me. “She’s playing the right game.”

Jordi McArthur, a member for 30 years, stood nearby waving a flagpole with the Scottish, Welsh and Catalan flags side by side. “We’re happy to wait until we know what is happening with Brexit,” he said. “But at the same time, we want a referendum. It won’t be Nicola’s choice. It will be the grass roots’ choice.”


No Gerrymandering

Party leaders may come and go, but SNP members can rely on one thing at conference – the stage invasions of the pensioner Gerry Fisher. A legendary dissenter, Fisher refused this year to play along with the party’s embrace of the EU. Clutching the
lectern stubbornly, he told members: “Don’t tell me that you can be independent and a member of the EU. It’s factually rubbish.” In the press room, where conference proceedings were shown unrelentingly on a big screen, hacks stopped what they were doing to cheer him on.


Back to black

No SNP conference would be complete without a glimpse of Mhairi Black, the straight-talking slayer of Douglas Alexander and Westminster’s Baby of the House. She is a celebrity among my millennial friends – a video of her maiden Commons speech has been watched more than 700,000 times – and her relative silence in recent months is making them anxious.

I was determined to track her down, so I set my alarm for an unearthly hour and joined a queue of middle-aged women at an early-morning fringe event. The SNP has taken up the cause of the Waspi (Women Against State Pension Inequality) campaign, run by a group of women born in the 1950s whose retirement age has been delayed and are demanding compensation. Black, who is 22, has become their most ­articulate spokeswoman.

The event started but her chair remained unfilled. When she did arrive, halfway through the session, it was straight from the airport. She gave a rip-roaring speech that momentarily convinced even Waspi sceptics like me, and then dashed off to her next appointment.


Family stories

Woven through the SNP conference was an argument about the benefits of immigration (currently controlled by Westminster). This culminated in an appearance by the Brain family, whose attempt to resist deportation back to Australia has made them a national cause célèbre. (Their young son has learned to speak Gaelic.) Yet for me, the most emotional moment of the conference was when another family, the Chhokars, stepped on stage. Surjit Singh Chhokar was murdered in 1998, but it took 17 years of campaigning and a change in double jeopardy laws before his killer could be brought to justice.

As Aamer Anwar, the family’s solicitor, told the story of “Scotland’s Stephen Lawrence”, Chhokar’s mother and sister stood listening silently, still stricken with grief. After he finished, the delegates gave the family a standing ovation.
