Not the best photos but here is an Eastern Crowned Warbler, one of the several phylloscopus warblers that can be seen in China. The first thing that struck me about this bird from underneath, before I saw the crown stripe, was the size and colour of the bill – very large and orangey compared with the superficially similar Arctic Warbler. The lower mandible is completely pale without any dark tip. The bird also showed a subtle pale yellow vent that wasn’t obvious, especially in the dappled light as it foraged among the leaves.
