Record is for the duck being held by the woman in the black jumper. This duck was released immediately after the comparison photos were taken.

The other two are PBD x mallard hybrids, caught as part of dumped domestic mallard removal efforts by the Pacific Black Duck Conservation Group: https://www.facebook.com/groups/pacificblackduckconservationgroup

The first photo's hybrid has a green/yellow bill (harder to see in this photo), patchy facial markings, and legs are a little bit too orange. This one also had white trims above the speculum.

The female in the second and third photos:
Mainly the lower face stripes and cheeks that are different. Both sexes should look like the pure one, a thinner stripe, and Cleary defined cream face patches. The hybrid’s cheek cuts into the cream patch while the pure’s continues to the back of the neck. The hybrid's eye stripe doesn’t surround the eye, which we see a lot with hybrid ducklings. Her crown was a bit too streaked for a female.
