Swift survey

March 17th, 2010

The RSPB is gathering extensive information about exactly where swifts are nesting in the UK.  It is suspected that their rapid decline in recent years is linked with a drop in suitable nesting sites, as buildings are modernised.

The first year’s survey reveals that of the houses where swifts are nesting:

  • Over half (51%) were built before 1919
  • Exactly a quarter were built between 1919-1944
  • Over half (52%)had been known swift nesting sites for more than 10 years
  • Almost a fifth (16%) were considered threatened
  • Almost 5% of swifts were recorded in churches

The data will be used to make sure that exhilarating displays of screaming swifts continue being part of British summers.

Magpies: Not guilty

March 12th, 2010

The clamour for magpie culls is like the baying of a crowd at a witch trial.  There’s no basis in fact for the claim that magpies are threatening British songbirds, only entrenched irrational ideas about corvids.

Organisations like the Songbird Survival Trust have in the past made badly misjudged calls for such culls. The real cause of population declines of species such as the bullfinch and yellowhammer is human activity: unsustainable land management, unecological farming practices and rampant urbanisation.  A new large-scale study published in the Journal of Applied Ecology has confirmed this.

Aggressive duck sex

February 8th, 2010

Here’s an utterly daft one from The Daily Telegraph: Locals are concerned that the overly aggressive mating habits of a group of amorous ducks will force visitors away from Thirsk, the rural North Yorkshire market town, and destroy tourism. Read

Kestrel and Barn Owl fight over vole

February 4th, 2010

Wildlife photographer Mark Hancox was in the right place and the right time to get these images of a cheeky kestrel stealing a barn owl's breakfast...

Amazing pair of images in the Daily Telegraph here of a kestrel and a barn owl’ battling it out over a vole. By wildlife photographer Mark Hancox.

Prisoners help bird count

Taboos about wild birds

January 31st, 2010

In her classic account of English rural life, Lark Rise to Candleford, Flora Thompson records attitudes to wild birds towards the end of the 19th century.   At a time when egg collecting was a respectable hobby, country boys would engage in wholesale nest robbing and hunting of small birds. The families were chronically poor, and casting a net over a hedge of roosting sparrows would secure a meal:

One boy would often bring home as many as twenty sparrows, which his mother would pluck and make into a pudding.  A small number of birds, or a single bird, would be toasted in front of the fire.

But Thompson notes that the birds in this popular rhyme were left alone: Read the rest of this entry

In praise of the little owl

January 27th, 2010

Michael McCarthy laments the sad decline of the little owl (Athene noctua) in Britain in today’s Independent, noting that unlike other introductions, they have not spelled ecological disaster, forming an attractive addition Britain’s birdlife. They were introduced by Victorian gentleman-ornithologists in the 1870s who wished to pay testament to their fame in Greek mythology. Little owls were linked to the godess Athena, perhaps because they bred in her temple, the Parthenon in Athens. The bird also became the symbol of the city, and its bug-eyed image was such a feature of Athenian silver coins – that they were known as “owls”.

Coincidentally, I came across last week this entry by George Orwell spotting a little owl back in January 1940,

No thaw. Unable to unfreeze pipes etc. Saw a little owl today – have not previously seen any of these round here.

Huge flock of corn buntings

January 19th, 2010

Farmer Steve Bumstead has always considered wildlife when managing his farm, leaving aside field margins and not ploughing until after Christmas so birds can forage among the stubble.  He’s been rewarded this winter by an unprecedented number of corn buntings flocking on his land - no less than 700, which has been estimated as 4% of the entire corn bunting population in the UK. The unusual size of the flock is thought to be a consequence of the recent prolonged freezing weather.

The corn bunting has been in sharp decline as a consequence of modern farming practices, so conservation researchers will be investigating Steve’s Bedfordshire farm to try and learn exactly why it is so attractive for them.  RSPB Photo by Steve Round

Mull’s sea eagles thriving

January 18th, 2010

White-tailed eagles on the Isle of Mull are thriving with 20 pairs now nesting on the Scottish island. The Mull Eagle Watch Partnership said 10 chicks had fledged from seven nests during last year’s breeding season. It also said 6,000 people a year were visiting the island to see the birds also known as sea eagles, which had boosted the local economy by £2m. The birds of prey originally colonised Mull in 1983 and produced the first successful fledglings in 1985 after being reintroduced to the nearby Isle of Rum 10 years earlier, BBC

Across Scotland a total of 46 pairs of white tailed eagles managed to successfully rear 36 chicks.

Praise for feeding birds in winter

January 14th, 2010

One of the Guardian’s editorials today is entitled In praise of… feeding birds in winter:

Feeding birds this month offers a rare chance to see redpolls, yellowhammers and tree sparrows among the robins, finches and tits that more often make up backyard populations. It will also keep them alive. Read

Lundy Island becomes first marine conservation zone in England

January 12th, 2010
National Trust Lundy island, Devon

The waters around Lundy Island today became the first marine conservation zone in England as part of a project to create a network of protected areas. The Guardian

Lundy is the largest island in the Bristol Channel, and lies 19 km off the coast of Devon. The number of puffins on the island which may have given the island its name, declined in the late 20th and early 21st centuries, with the 2005 breeding population estimated to be only two or three pairs, as a consequence of depredations by brown and black rats (Rattus rattus) (which have now been eliminated) and possibly also as a result of commercial fishing for sand eels, the puffins’ principal prey. Since 2005, the breeding numbers have been slowly increasing. Adults were seen taking fish into four burrows in 2007, and six burrows in 2008. More on Wikipedia

Peregrine falcon filmed hunting at night

January 12th, 2010


It has long been known that peregrines hunt at night, but film evidence has been lacking. Now, webcameras installed at the Derby Cathedral Peregrine Project have captured them doing it in the dark.

Aided by city lights, at 10.45pm on a freezing winters night, an adult peregrine brings a freshly caught Woodcock back to its feeding place on the tower of Derby Cathedral. We see the bird struggling in the firm grip of the peregrine’s talons. But one swift bite to the neck of its prey swiftly dispatches it. But then the peregrine takes off into the night again, settling first on a projecting lead gutter, then flying off to take yet another prey item. Peregrines are known to cache food items for later consumption, and cold weather may well prompt them to stock up even more. At this time of year we see species like woodcock, golden plover, snipe, redwing and lapwing as favourite prey items, and evidence of prey items help us monitor what species are moving through our towns.

Peregrine Falcons first nested on Derby Cathedral in 2006. Four chicks fledged in mid-June 2009, but one died in a flying accident and another injured its wing and must remain in care. More here from the project.

The cold snap - Orwell 1940

January 11th, 2010

The Orwell Diaries is a remarkable blog which publishes George Orwell’s diary entries on the same date 6o years later. The entries are full of fascinating insights into the daily life of the author between  1937 and 1947 and include a surprising amount of observations on natural history. The comments by the readers are also, unusually, interesting. Here is his entry of 11th January from the cold winter of 1940:

No thaw. It would be possible to skate on the church pond, but unfortunately I have no skates here. The other ponds not bearing. Water beetles (the kind whose legs look like oars) can be seen moving about under the ice. When a brick lies in the bottom in shallow water, there appears in the ice above it a curious formation the size & shape of the brick itself, presumably something to do with the temperature of the brick when thrown in being higher than that of the water. Turned up a woodcock in the common lane. No rabbits in the field today. Birds very bold & hungry. Rooks in the vegetable garden, where they do not usually come. One or two primroses & polyanthi budding, in spite of the frost upon them. One of the elm trees apparently bleeds a brown-coloured stuff, sap or something, & large icicles of this hanging down, looking like toffee. Milk when frozen goes into a curious flaky stuff like flaky pastry.

Orwell had an enduring interest in natural history which stemmed from his childhood. In letters from school he wrote about caterpillars and butterflies and he had a keen interest in ornithology. He also enjoyed fishing and shooting rabbits, and conducting experiments as in cooking a hedgehog or shooting down a jackdaw from the Eton roof to dissect it. Wikipedia

Grey squirrels don’t threaten birds

January 10th, 2010

Grey squirrel

A new study has found, contrary to popular belief, that grey squirrels do not have a significant impact on the populations of many of England’s woodland bird species. Although there was some evidence that grey squirrels may locally suppress the populations of some speciest through their preying on bird eggs, they do not appear to cause the birds any widespread or lasting harm.
