Niels Kaare Krabbe is an ornithologist and bird conservationist for many years based at the Vertebrate Department of the Zoological Museum, University of Copenhagen and tutored by Jon Fjeldså. His research interests include various aspects of ornithology, especially bioacoustics, conservation, and systematics and altitudinal replacements of Scytalopus tapaculos. He has worked extensively in the Andes, especially Ecuador, and wrote the passerine section of Birds of the High Andes (1990) and the accounts of most Andean species in Threatened Birds of the Americas (1992). He has helped build up a large tissue collection in the Zoological Museum and has authored or coauthored several bioacoustic publications and peer-reviewed papers in scientific journals.
Elaenia is a genus of passerine birds in the tyrant flycatcher family which occur in Mexico, the Caribbean, and Central and South America. Except by voice, specific identification is often difficult since many species are very similar. They are also known by the common name elaenia, which they share with the similar tyrant flycatchers of the genus Myiopagis.

Grey elaenia refers to birds that had been considered one species and have been split into three species:
