Key to Scientific Names in Ornithology
(Tyrannidae; Ϯ Golden-faced Tyrannulet Z. chrysops) Dr John Todd Zimmer (1889-1957) US ornithologist, taxonomist. "Despite the superficial similarity, I believe the group of Tyranniscus species with the unique wing pattern, syrinx and aberrant nasal septum, should be separated generically from the typical group of species. Surprisingly, there is no name available, so I propose: Zimmerius gen. nov., type Tyrannulus chrysops Sclater, 1858. ... The genus is named for the late John Todd Zimmer in belated recognition of his enormous contributions to the systematics of Neotropical birds and his recognition of the unique wing pattern in this new genus" (Traylor 1977).
