A new bird species has been identified in Cerros de Amotape National Park in Tumbes: the White-necked Jacobin (Florisuga mellivora), a member of the hummingbird family measuring 12 cm (4 in) in length, on average. Adult males have a blue head and breast, a dark-blue hood, iridescent upper parts, and a white abdomen and tail. And, as the name suggests, they have a white crescent on the neck.
