Birding in BC Community

Seen at Discovery Island (Victoria) Apr 19. I think they might be Western Sandpipers or Dunlins? Seen with BBPL and BLTU
Can anyone identify? Thanks!

Hi, yes these would be Dunlin. One clue is the black on the bellies that is starting to form as part of their breeding plumage. The bill is also longer and droopier than WESA.

Cheers,
