HK Wetland Park 21 Aug 2018 - season starts

The fall migration has started and I wish to take an ID photo for Swinhoe's Snipe (which both Pintail and Swinhoe's Snipe migrate earlier than Common Snipe) or find any early warblers. However, nothing special was seen. Only a Green Sandpiper (arrived last week), Great Cormorant (the long staying individual) and a Barn Swallow showing rufous underparts are interesting stuffs today.

Not a really good start of the season.
