[cobirds] Hybrid duck on South Platte River at 88th and Colorado, Adams County

Hi all,

A group of Tuesday Birders visited the South Platte River in Adams County yesterday morning.  Rob Raker noticed an interesting hybrid duck just south of the bridge at 88th and Colorado.  He took several photos which can be viewed on the following website:

The duck looks like a combination of gadwall and shoveler to me, or perhaps gadwall and mallard.  I expect some hybrid experts can give us a more confident explanation of this duck's origins. 

Thanks,

Mary Keithler, Unincorporated Arapahoe County near Cherry Creek State Park
