For all ducks: counted waterfowl from 4 sections they were congregating. Added up all totals and calculated percentages. Then approximated how many ducks were visible in the marsh that were not counted and used the calculated percentages to estimate number of species. 1095 GADW counted plus 430 by % calculation.

Male seen in same spot I had one a week or two ago; likely the same bird. Now nearly, if not completely molted into breeding plumage. Gray-bodied wigeon, pale orangey-pink chest, dark rufous head, creamy-yellow head stripe.

For all ducks: counted waterfowl from 4 sections they were congregating. Added up all totals and calculated percentages. Then approximated how many ducks were visible in the marsh that were not counted and used the calculated percentages to estimate number of species. 360 AMWI counted, plus 142 by % calculation.

Eurasian x American Wigeon (hybrid)

Relatively close for good study: first thing that caught my eye was the creamy-golden forehead stripe, which extended all the way to the back of the head. The rest of the head was dark brownish, but certainly not as bright or orangey as I expect from pure EUWI. Body wash orangey around the chest, but gradually got grayer towards the tail-end of the bird. Lastly, where the green 'eye-stripe' of a male AMWI is, this bird had a noticeably darker section of the face, which did appear greenish at certain angles. A very "in-between" bird.

Observed lone pale-eyed all black blackbird flyby relatively close. Size, shape, and proportions seemed identical to RUBL. Birds was identified by call: "chek" similar to that of a RUBL, but noticeably drier, harsher, and more raspy. I listened to the calls of both species immediately after to confirm my suspicions
