Observer: Mark Payne, WSM

Received an email from Phil Woollen regarding the aging of the RND. I did consider the age of this bird at the time of the find because of the undeveloped bill pattern. Obviously Phil had the same idea. I have included his images and his comments for your consideration.

Phil’s comments and images:

See pics attached. It threw me a bit as I was expecting a full adult summer plumaged male but I think this bird is just entering eclipse or a 1st summer male.


The bill pattern is quite faint but it is there.

  • The flanks aren’t pristine grey but flecked with brown.
  • Wing bar is a bit disconcerting  – not all one colour but not white as per Tufted Duck.
  • One photo shows clearly the chestnut collar which gives the bird its name.
