I A Munro 12 Posted May 13, 2019 This one might be a bit boring - is this a domestic/mallard hybrid, or something along those lines? It was noticeably larger/more aggressive than the surrounding mallards (pictured), with a darker/less shiny plumage, a paler bill, and a speckled breast. In a small man-made pond in San Francisco in May. Thank you! (You'll also notice a large crazy-looking Muscovy Duck which I assume is also domestic.)

The Bird Nuts 1,925 Posted May 13, 2019 (edited) Yes, the larger duck (besides the domestic Muscovy) is a domestic breed of Mallard. Edited May 13, 2019 by The Bird Nuts Quote Share this post Link to post Share on other sites
