ENR 5.6   BIRD  MIGRATION  AND  AREAS  WITH  SENSITIVE  FAUNA
1.

BIRD MIGRATION.

1.1

Bird migration occurs during the period early August to late March though birds are sometimes seen even early April.

1.2.

The birds normally fly at about 3000FT to 1000ft ALT. Inside the  Island they fly at ground level.

1.3  

Migrating Patterns and Altitudes.

There are three (03) major routes as follows:

 

  North Western  Route

The birds on northwestern route are reaching their destination in the Indu-Asian flyway. The birds enter the  Island through  Jaffna peninsula and they fly over the following areas.  

 

( Jaffna      Mannar        Wilpathu         Kalpitiya         Chilaw           Bellanwila            Hikkaduwa.)

  Eastern Route.

        This is the longest migratory route in  Sri Lanka . The birds of Indu-Asian fly way enter the island through  Jaffna peninsula and take the following route.

 

 (Jaffna Peninsula      Jaffna Lagoon      Elephant Pass     Chandikulam  

   Panama      Kumana       Yala          Bundala        Kalametiya    

   Upto Rekawa )

   Central Route.

Some birds take central route and enter the hilly area and their final destinations are Uda-walawe and Horton Plains. They are mainly forest birds and rapport (birds of pray) .

2.

REPORTING OF BIRD STRIKE

 2.1

To achieve more comprehensive statistics of bird strikes, the Civil Aviation administration is collecting information. All pilots on flights within Colombo FIR are therefore requested to report all cases of bird strikes or incidents where a risk of bird strike has been present initially to the Air Traffic Control via RTF and submit full report  using prescribed   BIRD STRIKE INCIDENT REPORTING FORM  CAA /AS/10  available at the  Aerodrome  AIS Units ( or download from  www.caa.lk ).

3. 

AREAS WITH SENSITIVE FAUNA.

3.1

Many species of birds as well as other animals are sensitive to noise from aircraft and over flying their breeding and resting places may be critical. Hence it is suggested to avoid over flying these protected areas below 1000ft height. These areas are shown on the chart on page ENR 5.6-3. Click here to view these areas ).
