On 28 September 2018, Erika and I discovered an immature Pied-billed Grebe on a Northfield lake, Striped sides of the head are typical of many juvenile grebes. Pied-billed Grebes retain remnants of these stripes until late winter, even after the grebe molts into its first definitive plumage. You can see this individual’s black bill ring beginning to become evident. Click here to see a photo of an adult.
