The Grenadan Euler’s Flycatcher was a subspecies of Euler’s Flycatcher (Lathrotriccus euleri (Cabanis)), an rather inconspicuous  bird species that is distributed over large parts of northern South America.

The Grenadan subspecies was restricted to the island of Grenada northwest of Trinidad and Tobago; it differed from the nominate form (see photo below) by its slightly more yellow colored underside.
