Although the distribution of Foothill Elaenia extends from northern Ecuador south to central Peru, it is known from only a few localities, and its population is believed to be declining due to ongoing deforestation. Therefore, its IUCN Red List status is rated as Vulnerable (BirdLife International 2012). Foothill Elaenia was not recognized at all as a distinct species until the early 1990s, however, and its range probably is more extensive that currently is documented.
Effects of human activity on populations
Foothill Elaenia is very vulnerable to habitat loss. The narrow elevational band that it occupies along the lower eastern slopes of the Andes is "diappearing at an alarming rate", primarily by clearing for subsistence agriculture (Coopmans and Krabbe 2000; see also BirdLife International 2012).
