A new species of hummingbird has been spotted and identified in Ecuador by a multinational team of ornithologists.
The bird has been named Oreotrochilus cyanolaemus, or blue-throated hillstar, for its deep blue neck and is about 11cm (4in) long.
Ecuador, which is rich in biodiversity, is home to 132 hummingbird species out of the more than 300 in the world.
Ornithologists say there are only about 300 blue-throated hillstars and that the species is in danger of extinction.
Francisco Sornoza is the ornithologist who led the team of researchers from Ecuador, Venezuela, Denmark and Sweden which made the discovery.
He told Agence France Press news agency that he had a hunch it could be a hitherto unknown species as soon as he spotted it through binoculars in the barren south-western highlands of Ecuador.
The area is historically poorly explored by ornithologists and the population of blue-throated hillstars is relatively small.
