Naturalists set up 'air traffic control' network to save birds
By Severin Carrell
12 October 2003

Naturalists are to set up a global "air traffic control" network to protect the nesting and feeding sites of tens of millions of endangered migratory birds.
Ornithologists are alarmed by fresh evidence that dozens of geese, 
wader and duck species now setting off on their annual migration south 
are facing extinction or, at best, a steep decline in numbers.
Some migratory birds face imminent extinction, such as the sociable 
lapwing, which flies from the Russian steppe to the Middle East. 
Others, like the red knot, which migrates the full length of the 
Americas from Alaska to Tierra del Fuego, are facing extreme and sudden 
decline.
Many of Britain's best-loved waders - such as the oystercatcher and 
ringed plover - have declined by up to 15 per cent since the 1980s. The 
Greenland white-fronted goose, which nests in summer in northern 
Britain and Ireland, is also dying out.
Now, in a concerted attempt to tackle the crisis, conservationists met 
in Edinburgh last week to begin drawing up the first world-wide 
tracking and planning system to protect the "air lanes", nesting sites 
and feeding places these birds use. Dr David Stroud, senior 
ornithologist at the UK's main conservation science agency, the Joint 
Nature Conservation Committee, said: "It's not a pretty picture at the 
moment.
"These birds are flying long distances as part of their biological 
cycle, but they need fuel and Britain's estuaries, for instance, are of 
major importance. Clearly, if you remove a key feeding site, these 
birds just don't have the physical ability to continue their migration. 
If you remove one link, then the whole migratory pattern can fall 
apart."
Last month, experts meeting in Spain heard that almost half of all the 
world's wader species, such as the long-billed plover, the dunlin and 
the bristle-thighed curlew, which flies non-stop from Alaska to the 
south Pacific, were in decline owing to human pressures, climate change 
and habitat loss.
The "air traffic control" proposal will focus on the world's nine major 
"flyways", by asking countries to monitor the numbers and types of 
birds flying through their airspace, plot their flight paths and 
protect or repair their nesting, breeding and feeding grounds. In some 
cases, governments will have to set up schemes to track poorly 
understood species - potentially using satellites and tagging 
techniques.
The scheme will provoke clashes over economic developments. One battle 
ground is Iceland's decision to build a massive hydro-electric dam at 
Karahnjukar, which will destroy the breeding sites of pink-footed and 
greylag geese. Despite being a major staging post in the "east Atlantic 
flyway" - which takes more than 90 million water birds from the Arctic 
through Europe to southern Africa - Iceland has refused to join a 
European and African scheme to protect migratory birds. And in South 
Korea, naturalists are furious at plans to reclaim a 155 sq mile 
inter-tidal wetland which could kill off the extremely rare 
spoon-billed sandpiper. The site is a crucial feeding place on the 
"East Asian-Australasian flyway" that runs from the Arctic to Australia 
and the south Pacific.
In the US, controversy surrounds the horseshoe crab fishery in Delaware 
Bay, a key feeding place on the "Atlantic flyway", which is blamed for 
a sudden decline in red knot numbers. The bird feeds on the crab's eggs 
but the crab is being chronically overfished.
