Me: For your information, there is a big flock of birds on the ground at the approach end runway 27R
TWR: Silence
Me: Repeated myself as above
TWR: Confirm you are ready for departure
Me: Negative, repeated myself as above
TWR: Yeah I don't know what they are up to
Me: Neither do I, so I am sure approaching aircraft would like to know
This was a US airport, I know EU-OPS requires an immediate report as soon as a potential bird hazard is observed.
