Hi bettle,
I think you do not need to blame yourself. It is about the time management of the late comer. I remembered that there was similar situation on 1st May Po Toi trip. The trip was delayed for around 20mins as well. It is not avoidable for this kind of situation. I think we may understand some are the first time to join this kind of trip and do not have experience on planning their time to the gathering location. Some may live far as well. There may be some improvement for this kind of trip. I think Sai Wan Ho may be better than gathering location than Aberdeen since MTR is usually more 'secure' public transport than taking bus or minibus. And it is easier for beginner.
At the end of the day, we just hope people enjoy bird-watching or learn something through the trip. I agree with John, bird-watching is a matter of luck. The thing we enjoy on bird-watching is being unpredictable. Otherwise, it is not exciting at all.
