Just saw 10 of these on Kents Pond. 🙂
We have a pair diving just outside my home in Port aux basques.
Excellent! Tufted Ducks are closely related to Greater and Lesser Scaup, which are much more common around Newfoundland. Tufted Ducks are quite rare outside of St. John’s, so your sighting is very noteworthy!
Here are several at Quidi Vidi Lake right now!
Lots on a river in North London, never seen them there before
