First documented records of Black-throated Flower-piercer, Diglossa brunneiventris (Lafresnaye, 1846) (Aves, Thraupidae), and Least Tern, Sternula antillarum (Lesson, 1847) (Aves, Laridae), on the southern coast of Peru

摘要

We report Black-throated Flower-piercer, Diglossa brunneiventris (Lafresnaye, 1846), and Least Tern, Sternula antillarum (Lesson, 1847), in the Tambo river estuary, Islay province, Arequipa department, Peru.Both species are newly documented from the southern coast of Peru.It is probable that D.brunneiventris has descended from the higher, inland portion of the Tambo river basin to the estuary.Sternula antillarum is considered a frequent visitor to the South American Pacific coast.
