From what I understand Ruddy Ducks are the only Polygamy North American duck. Torrent Ducks from Columbia are also one of the few duck species are monogamous and males will help take care of chicks. It is possible that males may sometimes follow females with chicks around, maybe because he is still her mate and feels he needs to protect her, or they just want to be around others of their own kind.

>>> Male ducks leave females behind once nesting starts. They tend to congregate at areas where they start their fall molt. One theory is that they are too small to defend their family any hoot, geese and swans are much larger and the males have more invested in their young since they mate for life, thus they stick around and help defend their family. A possible answer.

>>>>>> Evan and I, Alan Contreras, and Oscar Harper birded Baskett Slough NWR in Polk and Ankeny NWR in Marion today. Most notable at Baskett were large nesting populations of water birds, particularly Gadwall, of which there were nearly 40 adults and two groups of chicks visible. Over 20 Ruddy Duck chicks were also seen with two adult females and an adult male, as well as Coots and Grebes with young. Other presumably nesting birds were Pintails, Mallards, Stilts (chick seen), and Yellow-headed Blackbirds (female feeding juvenile). Also present were were Ring-necked Duck, Lazuli Bunting and Horned Lark from the 22 overlook, Yellow Warbler at the Narrows, and Wilson's Phalarope, Green Heron, Great Egret, and American Bittern on the transect road through the South Slough Pond south of Coville Rd.

The productive Willow brush at the Eagle Marsh Overlook produced a very cooperative Yellow-breasted Chat singing from the top of a snag, a Yellow Warbler, and a very unexpected Rooster (!) Cock-a-doodle-dooing from inside of a large Willow. One Green Heron and one American Bittern were present on the pond.
