Title: Pls Help ~~~
Post by DB on Apr 29^th, 2003, 8:07pm

Dear all,

I am now preparing a present on environmental impact in civil aviation.

I want the gather some info abt noise or other factors in aviation affecting birds.

1)Will the noise produced by aircraft scared the birds away ? e.g. the migratory birds not coming to hk for winter ect..

2) How high can the birds fly ? As the is helicopters and light aircraft movement in Shek Kong and even Mai Po area, will these BIG BIRDS scare the real birds away ?

3) Any other factors in aviation affect birds ?

Thanks a lot for your assistance!!
