Grey-headed Woodpecker (Picus canus, 灰头绿啄木鸟).
These woodpeckers live in forests throughout Europe and Asia. But they are seldom present in Changsha: there is not enough dead deciduous trees left standing in the heavily curated woodlands of the parks and Yuelu Mountain. This one braved a few morning hours at Yanghu Wetland Park, searching for food in a few bare branches. Where there is a natural space for them, a they will occasionally appear. This woodpecker also has a long and pensive (even mournful) call, which starts at a high pitch then rapidly falls off.
