Note 218 — THE LABRADOR JOURNAL (continued 2)

This appears to be an error, reflected in all of Audubon's published works. The Cayenne Tern of Audubon, as described and figured by him, is Sterna regia, which has never been known to occur in Labrador. Audubon never knew the Caspian Tern, S. tschegrava, and it is believed that this is the species which he saw in Labrador, and mistook for the Cayenne Tern—as he might easily do. See Coues, Birds of the Northwest, 1874, p. 669, where the case is noted.—E. C.
