I would like to sound the collective wisdom of this my readers… One of these goldeneyes is easily identifiable as a female Common Goldeneye (rounded head and black bill with a yellow tip). The other, however, is a bit of a challenge. The bill is the right size to be a Common, but the colour is off (too orange) and the head is perhaps a bit more peaked than it should be. Could it be a hybrid female Common X Barrow’s?
Both birds were taken February 20, 2016, on Stanley Park’s Lost Lagoon in Vancouver, BC with a handheld Nikon D5200 and AF-S NIKKOR 200-500mm f/5.6E ED VR, cropped. Not baited, called in or set up.
