Numbers far down from a month ago but still two rafts of 200 each on the main pool a scattered smaller groups throughout.

55
Redhead

Ring-necked Duck
3
Greater Scaup

A pair fairly close to the dike on the main pool and a single adult male in another part of the main pool. The pair was only slightly smaller than a nearby pair of REDH, typical more elegantly curved backs, thicker necks, and larger heads than LESC. Both had extensive black surrounding the nail on the bill. Both diving actively so head shapes not field guide classic but large, longer horizontally than vertically, not as rounded as in a relaxed posture but still round with the highest point above the eye and lacking the LESC topnotch. Female had noticeably pale ear patch and more extensive white at the base of the bill than female LESC. Male with clean white flanks, though as is typically for male LESC in spring, many of the drake LESC had flanks nearly as white. Second male GRSC was swimming right in front of a male LESC. Creating a direct comparison of size and structural features and was classic in every way.

Lesser Scaup
2200
Ruddy Duck

Best estimate. Didn’t try to count. Could easily be far higher. 2/3 of the main pool was covered in raft after raft of rudu. Pretty impressive

Herring Gull
1
Iceland Gull (Thayer's)

This 1st cycle individual still had the beautiful uniformly creamy brown appearance of juv THGU. Some in spring begin to look patchy but this one was pristine. Dark browns, not blackish primaries still with some pale edges

1
Lesser Black-backed Gull

Adult in full alt. Of a size with the nearby CAGUs but heftier with a stouter bill, likely a big male. Mantle several shades darker than nearby CAGU giving the appearance of a dark mantle gull not a gray mantled gull. Saw it change positions several times and dark appearance was maintained, not a trick of the light. Tertial crescent small, not SBGU or WEGU.

16
Caspian Tern

Exact count

2
Neotropic Cormorant

Two obvious dinky cormorants with short, weak bills sitting on the bank in the midst of a group of DCCO. Too far to see facial details but the comparison made the ID easy
