Last Friday, I saw what looked to me like a male Mallard x Mexican Duck hybrid. Yellow bill, brown head with darker crown, dark eye line, and brown tail coverts all seem to suggest male Mexican Duck. However, white in tail and partial upcurve of central tail feathers seem to suggest male mallard (see photos). Seen in small pond in company of group of 9 mallards on the north-east side of Pleasant View Marsh, just west of 47th St. eBird checklist with photos: https://ebird.org/checklist/S75280196
I'd welcome feedback from more knowledgeable folks. Thank you. Willem van Vliet Boulder -- You received this message because you are subscribed to the Google Groups "Colorado Birds" group.
