New York City plans to trap and kill up to 2,000 Canada geese this summer in an attempt to avoid the type of collision that caused a jet to ditch in the Hudson River in January.

The hunt will take place on dozens of city properties within eight kilometres of Kennedy and LaGuardia airports.

Aviation officials have culled the bird flocks on airport property for years, but this will mark a major expansion of the effort into other parts of the city, including about 40 public parks.

The roundup is being timed with the molting season, when the geese can't fly. It is scheduled to begin within a week. The geese will be gassed.

U.S. Airways Flight 1549 had just taken off from LaGuardia Airport in New York on Jan. 15 and climbed to almost 1,000 metres when the plane hit a flock of Canada geese and lost thrust in both engines.

Capt. Chesley Sullenberger decided to ditch into the Hudson rather than risk crashing in the densely populated area of New York and New Jersey. Everyone aboard survived.
