Birds

The theory of evolution is dominated by the utilitarian logic of natural selection: adapt or die, survival of the fittest. But consider that ‘fit’ has two meanings these days: ‘healthy’ but also ‘hot’. There is another evolutionary mechanism that scientists have taken a longer time to appreciate – seduction by the hottest, rather than survival of the fittest. It generates very different and much stranger outcomes. Perhaps even the big brains of human beings evolved as seduction devices more than survival aids. When an animal selects a mate, it can shape the future of its species just like breeders of dogs shape different breeds. Sexual selection through mate choice is

The last straw Farmers are threatening to strike over the government’s changes to inheritance tax in what is being described as a first in Britain. Besides France, where farmers regularly protest, India witnessed a farmers’ strike in 2020, which was eventually settled after the government dropped proposed new laws. But one of the earliest farmers’ strikes was conducted by the Farmers’ Holiday Association in Iowa in 1932, by farmers protesting at consistently low prices for their products. The idea was that farmers would go on ‘holiday’, refusing to sell any of their produce. Few, however, joined, leading to pickets blocking rural roads with telegraph poles. One policeman was killed, but

I own a grass farm in the Chilterns which provides grazing for horses and haymaking. It also provides habitat for hares, skylarks, lapwings and field voles (the staple diet of my resident pair of barn owls) – which is why I am so set against the red kites. Between 1989 and 1994, red kites from Spain were imported and released into the Chilterns by the RSPB and Natural England. The population here had dwindled and the RSPB describes the reintroduction programme as ‘one of the UK’s biggest conservation success stories’. But it’s only a success story if you ignore the devastating effect red kites have had on other wildlife. The

The lie’s the thing Sir: Your leading article (‘Partygate’s hangover’, 2 April) maintains that if the Prime Minister receives a fixed penalty notice, he shouldn’t have to resign. No fair-minded person would disagree with this, for such a resignation would indeed be absurd. However, there is a more serious issue. The Prime Minister repeatedly assured the House of Commons that all Covid guidelines were followed in Downing Street. If it is found that he knowingly misled MPs with these claims, then the Ministerial Code is entirely clear: he would have to resign. John Hatt Firbank, Cumbria Thatcher’s war Sir: Charles Moore writes that if Margaret Thatcher had failed to retake

Early this year, five dead herring gulls were discovered on a Cornish beach, and when tested it was found they had bird flu. This should have provoked serious concern: these were the first gulls to be found carrying bird flu in Britain. But because of the war and because we’re sick of epidemics, it was largely ignored. The dead gulls matter because gulls live among us. Some 75 per cent of our herring gulls are now urban. There are 100,000 to 180,000 breeding on rooftops in England, according to the 2020 national census. Tim Newark sounded the alarm in these pages that year, but since then the problem has grown

Bitterns are booming, both literally and metaphorically. These handsome brown birds from the heron family make a noise quite unlike anything else in Britain and we are lucky to be able to hear it. If there is such a thing as a birding bucket list then hearing a bittern’s ‘boom’ — the loudest bird call in the country — should be on it. Before the bittern starts booming he performs a warm-up ritual called grunting. He strengthens his throat muscles, which expand to turn his gullet into an echo chamber. His powerful muscles make up a fifth of his body weight and can propel the sound of his boom for

China has peaked Sir: Niall Ferguson makes some good points about the nature of Xi Jinping’s imperial aspirations but misses two important parts of the picture (‘The China model’, 8 May). First, the Chinese Academy of Science predicts that China’s population will peak at 1.4 billion in 2029, drop to 1.36 billion by 2050, and shrink to as few as 1.17 billion people by 2065. They even forecast that China’s population might be reduced by about 50 per cent by the turn of the next century. And second, China’s economic rise is stalling. Rather than being on track to displace the United States as the next economic superpower, China now

St Tiburtius’ Day, on 14 April, is traditionally when you will hear the first cuckoo. Since at least the Middle Ages, cuckoos have been seen as heralds of spring. They are also often associated with romance, and yet they are some of the cruellest birds found in Britain. The adults arrive in this country at the end of March or the beginning of April and depart in late July or August. They return to central Africa and fly, either via Italy, resting near the River Po and continuing over the Sahara, or stopping in Spain before entering Africa from the far western end. They live mainly in and around the

My tawny owl has been self-isolating. I say mine but in truth she chose the nest box in my neighbour’s garden rather than the one I almost killed myself to install, balancing it on my head as I scaled a rickety old ladder. A couple of months ago I spotted the owl, happily sitting in the box’s entrance in the weakening sun. A pattern was established. Every evening as day drained away, I went into the garden, balancing my old Zeiss binoculars alongside a glass of white. The owl would fly in silently from the south, sit around for a while and then disappear into the box. These regular sightings
