Hi there,<\/p>\n

Today (24 December 2015) I bird-watched along the Rideau River at\u00a0 Strathcona Park. I stayed on the W side of the river and birded from Strathcona S to Hurdman bridge and back. I encountered some birds of interest and wanted to share some photos. First, I observed a first-winter Barrow’s in with a raft of Common Goldeneyes of various sex\/age; this is the second first-winter bird I have encountered in the Ottawa area this winter. My first observation of a first-winter bird was at Bate Island on 17 December.\u00a0 Later on, I observed a “yellow-billed Common Goldeneye in with standard-issue females of varying age class.<\/p>\n

Head & Bill GISS as an Identifier of Barrow\u2019s Goldeneye<\/strong><\/span><\/p>\n

Important features of note are the short and stubby bill; steep forehead; flat crown and a touch of a crest at the rear. The head & bill GISS is vital in a case like this as the familiar white crescent and body spur (etc.) to a male and the deep chocolate brown \u201cboxy\u201d head and pumpkin orange bill to a female are not available as identification cues. With\u00a0 Common, the proportionally longer bill; sloped forehead; and peak near the centre of the head show through in a variety of postures.
