So I’ve HEARD of intersex birds, especially ducks, but never seen one until today. During a dog walk through Black River Riparian Forest, accessed from Oakesdale/Monster Rd. on western edge of Renton, I had a Mallard with female body and big black splotch on bill, but iridescent green head like a drake, save for buffy-brown cheek.

Not as sexy (pun intended) as that gynandromorph cardinal in Pennsylvania, but still a cool bird to stumble across. Clearly paired with a “normal” male Mallard. If you believe the internet, it is probably an aging female whose estrogen levels are low.
