Greetings all:
The balance of opinion was that the bird I photographed at Lake Two
yesterday had at least three traits typical of Greater Scaup and that,
with three reviewers weighing in, the bird 'was a Greater Scaup', 'was
probably a Greater Scaup', and was 'good for Greater Scaup'. This is
what eBird reviewers get up to with challenging photographs:)
If anybody is interested in looking at the picture I will send it to
individuals upon request.
