Radio tracking

I explained earlier that we were be putting radios on the falcons. This is what I was talking about. From the small size, I think this is a male falcon. The hood keeps him calm. Sometimes they even fall asleep. The radio is strapped on like a backpack with some string that is designed to eventually weaken and fall off. The radio emits a beep every second which is detected by an antenna that we have. We rotate the antenna and subjectively judge which direction got the strongest beep. That then is the direction of the bird.
