Birdwatcher is a word which has mostly avoided the internet generation entirely. Birdwatcher is an automated telemetry system with two pilot inputs, an A button and and a B button, and the rest of the inputs were specific telemetry inputs on the aircraft. The A-12 had a Birdwatcher system, as well as the CIA version of the U-2. Both of these aircraft or similar variants (U-2S, SR-71) were transferred to the 9th SRW, 4080th, and other related divisions.

Birdwatcher also involved a time-division aspect to the received signal. A physical measuring apparatus is used to determine the source module of the telemetry burst from a strip-chart recorder.
