Very similar to Golden-faced Tyrannulet. Vocal and DNA differences. Usually has a lighter eye, but apparently this is not guaranteed.

An amazing nest-builder. Note light colored eye. The Guianan Tyrannulet in northeast Brazil and the Guyanas was recently split from this species.

Once called the Venezuelan Tyrannulet, but those in the Santa Marta and Perija mountain ranges are now called Specious Tyrannulet or Spectacled Tyrannulet. Found at higher altitudes than other Zimmerius in its range (Golden-faced Tyrannulet and Coopmans's Tyrannulet).

Similar to, and split from the Golden-faced Tyrannulet, but even smaller. In the range of the Spectacled Tyrannulet, which includes Santa Marta and Perija, Coopman's is found at lower altitudes.

Split from the Paltry Tyrannulet found further north mainly because of smaller size and vocal differences.
