Difference between the Greater Scaup and Lesser Scaup?

As we know there are many variations of ducks and one among those is scaup ducks. These scaup ducks are again divided in3to two other divisions which are greater scaup and lesser scaup ducks. The greater scaup and lesser scaup are some of the most challenging waterfowl for birders to distinguish between, and there is no single indicator that is clear for either bird. Birders who learn the many tiny differences between the two birds, however can gradually become proficient in telling them apart. The Greater Scaup somehow looks like this and the Lesser Scaup looks like this .

And another the most difficult challenge which comes up is how to identify between the duos. It might be easy for the professional birders but not who are not and are newbie to this field. When examining the scaups, check for these characteristics to distinguish between the greater and the lesser:

 

-Its size

The greater scaup is the larger bird than the lesser scaup ones

-The bill

The size of the bills are almost similiar but when you keenly observe it you could notice that the greater scaup has a larger than the other ones.

-The head shape

The greater scaup has a more rounded head and nape, with the highest point of the head closer to the forehead. The lesser scaup has a straighter neck and more oval head with the peak further back on the head, and a resting lesser scaup will show a notch or corner toward the back of the head

-The feathers

The greater scaup has narrower barring on its back, and the barring rarely extends onto its white flanks. The lesser scaup, on the other hand, has heavier barring that frequently extends lower on the white flanks

-The wings

Greater scaups have more extensive white on their primary and secondary feathers that extends nearly to the tip of the wing, while lesser scaups have white only halfway along the wing before it fades to brownish gray.
