Three videos picked because they teach something a written page cannot — the rhythm of counting birds, what a quantum compass might look like in motion, and the real answer to the question every visitor asks. Bring headphones; the audio is worth it.
The flock-estimation video for first-time counters. Scan counting, blocking technique, the grid method, avoiding double-counting in moving flocks. The framework — practice in the field is what builds the skill.
