Here’s the latest on Common Goldeneye (Bucephala clangula).
Status overview: Globally, this species is currently listed as Least Concern by major authorities, with stable or locally variable populations in many regions. This stability is attributed to a wide range and large population size, though local declines can occur where habitat or nesting cavities decline.[2][4][5]

Notable caveats:
If you’d like, I can pull a quick country-by-country snapshot (Canada, USA, UK, Europe) or provide a short chart showing observed trends over the last two decades. I can also tailor the update to Montréal, Quebec, if you want regional focus.

Common goldeneye populations seem to be relatively stable despite threats to their aquatic habitats, such as acid rain, contamination, and habitat destruction. They are considered "least concern" by the IUCN because of their large range, large population size, and no documented population declines. They are protected as a migratory bird under the U.S. Migratory Bird Act. Population densities may be most affected by availability of nest cavities.

consult.defra.gov.ukThe male Common Goldeneye adds a bright note to winter days with its radiant amber eye, glistening green-black head, and crisp black-and-white body and wings. The female has a chocolate brown head with the same bright eye that gives this species its name. These distinctively shaped, large-headed ducks dive for their food, eating mostly aquatic invertebrates and fish. They nest in tree cavities in the boreal forest of Canada and Alaska; look for them on large rivers, lakes, and Atlantic,...

www.animaldiversity.orgIn North America, the Common Goldeneye breeds in tree cavities across the boreal forest regions of Canada and Alaska. The Western population has shown a stable or decreasing trend in the last two decades following a long-term increase between the 1960s and the 1990s. The Eastern population trend has remained stable over this period. The harvest of Common Goldeneyes has been decreasing since the 1980s, with most of the harvest taking place in eastern Canada. This species has been identified as...

www.audubon.orgThe best way I know of to get a rare bird to fly the coop is to write about it. So by the time you see this article the two drake common goldeneyes that have been hanging out at Lake Junaluska for the past week or so will likely have vanished. But they have been consistently sighted along the shorel...
