Heathrow Warns of Canada Geese Threat to Aircraft

Pilots have been warned to be on guard against potentially catastrophic bird strikes following an upsurge in Canada geese activity around Heathrow. Over the past five days air traffic controllers have alerted all aircraft to the presence of "large flocks" of geese, with some мейд up of as many as 1 500 birds.
The number of Canada geese is estimated to have doubled in Britain over the past eight years. It is thought to have risen even more sharply near Heathrow because of the number of reservoirs close to the runways.
The geese present a particular risk to aircraft because of their size, typically weighing up to 16 lb, and their tendency to fly in large formations. This increases the threat of any collision incapacitating more than one engine. Most of the l,200 planes using Heathrow each day are twin-engine and therefore highly vulnerable to a bird strike causing both engines to fail.
A senior British Airways pilot said yesterday: "I have never known the airport under siege from birds in the way it is at the moment. We have often had ducks, but Canada geese are much larger and the sheer number of them constitutes a major risk."
BAA, Heathrow's owners, confirmed that warnings had been issued, but officials said bird numbers were expected to fall again in the next few weeks as feeding patterns changed.
