Beetle, We are very sorry to make you blame yourself. We think the major problem was the late comers.
Of course no one can guareentee finding birds in the open waters; even at Po Toi. As a leader, you are too tired after searching birds for several hours and only take a short sleep was much acceptable. Also the weather was fine that birds migration takes place some days earlier may be the problem.
We are really enjoying this boat trip very much.
