Birds of Chignik Lake: Black Scoter – Springtime Courtship on a Wilderness Lake

Female (left) and male Black Scoters frequently visit Chignik Lake in springtime, usually in what appear to be mated pairs or small groups of hens and drakes. (Chignik Lake, May 3, 2018)

Formerly lumped together with coots and until fairly recently considered conspecific with European Common Scoters, not as much is known about Black Scoters as is known about most other North American Ducks. A few nests have been found – depressions the female lines with grass in treeless environments. I witnessed a pair mating on the lake, so it might be presumed that they intended to nest someplace not too distant.

After making his intentions known with displays featuring wing-flapping and rearing up with his bill pointed to the sky, Sir mounted his Good Lady. With Narver reporting the species as common on both lakes during summers, Black Scoters must surely nest in the Chignik Drainage. (May 3, 2018)

Considered “sea ducks,” nearby ocean bays are likely where Black Scoters winter. I never saw them on the lake earlier than spring. With the male’s black plumage and bright orange bill, these ducks are unlikely to be overlooked. For that matter, the female too is fairly easily distinguished by her contrasting dark brown cap and pale, almost white, face. If you can get a look at the bill, check for a distinctive hook at the tip. This may be an adaptation for digging up shellfish, the Black Scoter’s favorite food.

Another nearly diagnostic characteristic is the call the drakes produce. Gentle, high-pitched tones sung in a minor key are the norm. At other times the whistling sounds slightly reedy, though still quite pleasant. It’s a music I’ve come to associate with springtime at The Lake.

Perhaps Chignik Lake is only a stopover for this pair as they travel up the drainage to the marshy tundra around Black Lake where the female will make her nest. Or maybe they’ve already got a nest, above the tree-line on one of the mountains overlooking the lake. The Chigniks remain a wonderfully under-explored and seldom studied corner of the world.
