Alfred Newton, 1911 Encyclopædia Britannica, Volume 15… (1911)
“ With the exception of Galbula melanogenia, which is found also in Central America and southern Mexico, all the jacamars inhabit the tropical portions of South America eastward of the Andes, Galbula ruficauda, however, extending its range to the islands of Trinidad and Tobago. [2] Very little is known of the habits of any of the species. They are seen sitting motionless on trees, sometimes solitarily, at other times in companies, whence they suddenly dart off at any passing insect, catch it on the wing, and return to their perch. ”
