I was a new controller and just assigned to my first duty station, Falcon Field in Mesa Arizona. I had a pretty good working relationship with my crew mate. It was slow and we had the frequencies on the speaker so we could use handsets instead of wearing headsets.
Out of nowhere we get a report of birds on the north side of the field flying south. So as is required of us, my crew mate starts making a cautionary statement for birds INVOF the airport. As he is doing this I scream as loud as I can, “CAW CAW CAW.”
