Common Goldeneyes, in my experience, rarely let you get very close. They are relatively common here in winter and I also see them while doing Breeding Bird Surveys in June in Northern Ontario.
Females, apart from the golden eye, look nothing like males:
They winter on open lakes, rivers and bays in small flocks.
Common Goldeneyes eat mainly aquatic invertebrates, fish, and fish eggs, with vegetation such as seeds and tubers making up less than a quarter of the diet.
We’d never know how high we are, till we are called to rise; and then, if we are true to plan, our statures touch the sky. – Emily Dickinson (1830–86)
