I saw these birds in Tai Po Kau this morning, within a bird wave. Aside from the second one, where i think it could be a juvenile Mountain Tailorbird, I have no clue about what these birds could be. The third one (really a poor photo) was clearly a warbler on the field, but I don't know any common warbler with yellow breast...
Thanks a lot in advance
