The 2 “Goldeneye” we’re most likely the hybrids that are resident here ,presumably the offspring of one of The Male Hooded Merganser’s that frequent the reservoir, mating with who knows what ? !!
A short stop this lunchtime at Hawkridge reservoir produced 2 goldeneye with another diving duck that I wasn’t familiar with. Having returned home and checked my guides it was a male hooded merganser. The large white cheeks, black back and pinky brown sides made identification clear. Easily visible from the roadside parking spaces. That is 2 rarities/escapees this week for me.
