I went with the wife late last week, up early, to the top of Tai Mo Shan mountain to find this chappy. I think that qualifies as twitching!
He was at the very top of the tree, and whilst i was taking the photo he fluffed his feathers..as they do, with this great effect.
Here we are looking up and listening: oh, video not working...
here are some more shots, and you have to take my word for it, it was LOUD!
Here you can see his throat pouches hard at work.
Here is what he looks like, shot at 560mm at the top of tree with a 80% crop!
What bird is it? Is “twitching” just what it means or is it some sort of birdwatching term?
