Canadian government viewed Trump’s election as “positive news” for Keystone XL and energy industry

The Trudeau government treated Donald Trump’s election as “positive news” for Canada’s energy industry and welcomed the help of Canada’s main corporate oil group in lobbying the US administration, documents show.

Meetings conducted by senior government officials with TransCanada and the Canadian Association of Petroleum Producers (CAPP) reveal an one-sided approach more reminiscent of former Prime Minister Stephen Harper’s secret oil advocacy than Justin Trudeau’s green electoral promises.

Sinah Common, Hayling Island, Hampshire: Despite years of dedicated gorse-scanning this was the first time I’d seen one of these secretive little birds on my patch

The gorse thicket was ablaze with flower, but the heady coconut-suncream scent of the golden blossom was at odds with the biting wind and overcast sky. As a shower began to fall like a haze of iron filings, I decided to take shelter behind one of the well-preserved anti-aircraft gun emplacements – a relic from the second world war, when decoy fires were set on Hayling Island to draw the Luftwaffe away from the important military targets on nearby Portsea Island.

As I hunkered down against the concrete wall, I noticed a small, dark-coloured bird flitting through the furze like a restless sprite. I followed at a discreet distance as it crept through the low branches, gleaning insects from the needle-like leaves with quick, jerky movements. At first glance I thought it was a wren, but as I raised my binoculars it turned and cocked a disproportionately long, slender tail – not the short, stubby appendage I was expecting to see. I realised that I was looking at a Dartford warbler, Sylvia undata.

While the species has recovered from the 1960s population crash, continuing to increase in numbers and expand its range in recent years, Dartford warblers are largely sedentary birds. They breed exclusively on lowland heath and rarely travel far from their natal habitat. When food is scarce they will range more widely and can occasionally be spotted in coastal scrub during the winter months, but despite years of dedicated gorse-scanning this was the first time I’d encountered one on my local patch.

I wasn’t content with this fleeting glimpse, but “Darties” are secretive, skulking birds. My fingers reddened with cold as I waited in the hope that this one would emerge from the dense, dark undergrowth. As the rain eased off, my patience was finally rewarded. The bird – a male – perched up on the crown of a bush and I was able to admire his slate-grey upper parts, ruddy breast and vermilion eye-rings.

The instant he caught sight of me, the feathers on his domed-shaped head began to rise in the suggestion of a crest. Tail wagging, he scolded me with a harsh nasal “dzurr”, before vanishing back into cover.

It's been a year since the last South Australia blackout and when the Coalition brandished a lump of coal in parliament. And the progress since then has been remarkable – on the cost front, on storage, and the emergence of dispatchable renewables.

Poultry group which sold out-of-date meat to supermarkets may close three factories

Nine hundred jobs are under threat at three poultry plants belonging to 2 Sisters Food Group, the UK’s largest supplier of supermarket chicken, which has been dogged by a controversy over food standards.

The potential closure of two of the firm’s West Midlands factories in Smethwick and Wolverhampton, plus a third in Cambuslang in South Lanarkshire, follow a nightmare year for the company, which has included the closing of a further site in Smethwick as well as a Guardian and ITV undercover investigation that prompted production to be suspended for five weeks last autumn at the group’s West Bromwich plant.

CSIRO researchers use world-first genetic analysis to estimate population, but believe numbers could be as high as 12,800

About 5,500 great white sharks are cruising in the waters off Australia’s east coast, new research has revealed.

For the first time, the CSIRO has been able to put a number on the size of the white shark population using world-first genetic analysis.

It estimates there are about 750 adults living in waters east of Victoria’s southern coast, up to central Queensland and across to New Zealand.

Taking juvenile sharks into account, researchers believe the total east coast population sits at 5,460 – but could be as high as 12,800.
