Bornean Whistling Thrush

Possibly, it was picking scraps dropped by humans while eating. This area is the start and finishing point for the mountain climbers and a lot of them pause to eat here, either on the way up or down. Interestingly, I saw another one by a restaurant much lower down doing the same thing, rather like starlings and sparrows do. I think they are generally ground feeders and we were effectively on a first floor balcony overlooking it and it did on occasions come up to the balcony also.
