Summary Camptorhynchus labradorius probably bred along the Gulf of St Lawrence and coastal Labrador, Canada, wintering from Nova Scotia south to Chesapeake Bay, USA¹. The last confirmed specimen was collected off Long Island, New York, in 1875¹ (or possibly 1878²).

Ecology: Birds presumably nested on sandbars and around sheltered bays and, in winter, foraged in shallow bays, harbours and estuaries¹.

Threats Shooting and trapping on the winter quarters were certainly proximate factors in the species's extinction¹. Overharvest of birds and eggs on the breeding grounds could also have been a factor¹.
