Mike, 14 Amur Falcons seen together in a thermal towards the northern end of Mai Po at 1730 on the 23rd. Since they failed to land at the southern end of Mai Po it seemed reasonable to assume that they would roost at TBT. I had a dental appointment I couldn't blow off on the Monday morning, so was very pleased to hear from John that he had indeed found some. A couple were still present on the Monday afternoon and giving terrific views and photographs. Team work, what we need more of in HK!
