These are lovely ducks, this was a first for me, seeing a Harlequin in breeding plumage taken from the jetty at Barnegat..lots of wave action but didn't seem to bother the birds....

Looks like a succesful trip, glad you got to see these Paul. Although the whites are, well, white I find the darks a little too dark especially in the face/neck area. Perhaps some judiscious use of S/H tool, or shadow recovery in RAW conversion would help there. With the bird smallish in the frame even with a 50% crop I bet you were wishing for a little bit longer reach!
Congratulations on seeing these beauties Paul and for sharing with us. Agree with Daniel on the blacks . Like the moving water and the good eye contact in this capture.
Thanks Judy and Dan...yes would have loved to have my 300 with TC. Will experiment with S/H, Dan..could you please elaborate on shadow recovery in raw?
Paul, I'm not sure which RAW converter you use but in Lightroom the following sliders are available to manipulate the blacks/darks: Shadows, Blacks, Darks and to a lesser degree but sometimes helpful, Fill Light. You can also do localized exposure adjustments which can be pretty handy.
