28 November 2010 - near Shek Pai Wan, Lamma Island
Around 8:30 am I was spishing in a section of forest. Several birds responded to my spishing including a Mountain Taylorbird and this bird which I think is a Yellow-streaked Warbler. This bird was 20% longer than the Mountain Taylorbird and the calls were very high and sharp.
The photos aren't great but I think Radde's Warbler can be eliminated by the very thin bill. Dusky Warbler can be eliminated based on call and the yellow upper mandible. The only think bothers me about this bird for Yellow-streaked Warbler is that the undertail coverts appear white and I would expect them to be more buffy on Yellow-streaked Warbler.
