Common Goldeneyes have bred at Langdon Lake (Tollgate, Umatilla County) every year since at least 2004, including this year. Three adult male C. Goldeneyes were with 2 adult females on the lake on May 27 this year. Mark Ludwick photographed a female with 8 ducklings on June 8 (first report of ducklings this year). On June 12, I saw 4 adult females, one with 3 ducklings. Mary Betz reported (eBird) 2 females and 8 ducklings on Langdon Lake, yesterday.
I've never seen a Barrow's Goldeneye on Langdon Lake, only Common Goldeneyes. C. Goldeneyes arrive in spring as soon as the lake is ice free. Males usually depart by June 1, leaving the females to raise the broods. I believe any spring or early summer reports of Barrow's Goldeneyes, especially females, on the Langdon Lake are misidentified C. Goldeneyes. It's possible Barrow's may occasionally stop over on the lake during fall migration?
