Getting The Sparrows Back To Our Towns

The sparrow used to be a familiar sight in our towns and cities, but within a generation, numbers have plummeted.

Researchers say numbers started falling in towns and cities in the mid-1980s. Cockney sparrows are almost non-existent, and the species has almost vanished from London.

House sparrows are also disappearing from Bristol, Edinburgh and Dublin.

One of the co-authors of the study, Dr Kate Vincent, describes it as "one of the most mysterious and complex declines of a species in recent years".

This new research studied house sparrows in Leicester and surrounding villages.

The birds declined by 28% during the three-year study - but scientists found that while sparrow chicks were hatching, they weren't surviving.

'Lazy gardening'

Dr Mark Avery, from the RSPB, says the research suggests that a lack of garden greenery means that the insects that sparrows rely on to feed their young are in short supply:

"When even the common sparrow is declining, it shows the world is in a bad state," he says.

"Massive changes in population can happen in a very short space of time, even in species that start off as very common. For example there were 9 billion passenger pigeons just 50 years before they became extinct."

One place that sparrows continue to thrive is in St Ives, Cambridgeshire - more particularly, in Will Peach's back garden.

But as the lead author of the new sparrow research, he admits that, if sparrows didn't thrive in his garden, it would be a rather worrying state of affairs.

He attributes his sparrow success to honeysuckle, and being a "useless, lazy gardener".

"Honeysuckle attracts loads of spiders and insects, which the sparrows love," he says, "and leaving vegetation to grow gives the right conditions".

It certainly seems to work - two sparrows are, as we speak, perching on a nearby tree looking at us inquisitively, and the air is melodious with birdsong.

So, now you have an excuse for doing nothing in the garden - you're helping one of Britain's best loved, and rapidly disappearing, birds.

They are regarded as a pest in Oz

Quote:House sparrows are native to Europe and much of Asia, but because of its close association with humans, house sparrows are not spread widely throughout the world. House sparrows were introduced to Australia in the 1860’s. They are currently restricted to the eastern half of the Northern Territory, where they primarily inhabit urban areas, but may also be located around remote homesteads, where they survive on grains and seeds.
