Contributing Editor Kenn Kaufman provides tips for identifying birds in every issue of BirdWatching. In our August 2014 issue, he told what to look for to identify Buff-breasted and Sulphur-bellied Flycatchers, Northern Beardless-Tyrannulet, Greater Pewee, and Thick-billed Kingbird — flycatchers of the Southwest. He also included this explication of the word tyrannus:
A name like tyrannulet, or little tyrant, leads to questions about how the tyrant flycatcher family got that name.
The Swedish biologist Carl Linnaeus, who invented the system of scientific names in use today, gave the species name tyrannus to Eastern Kingbird (above) in 1758. The genus Tyrannus was established in 1799, making Eastern Kingbird’s full name Tyrannus tyrannus, and the name of the family Tyrannidae was based on that. In the 20th century, authors choosing English names for all the tropical flycatchers coined many terms like tyrannulet, pygmy-tyrant, and so on.
The name tyrannus seems appropriate for kingbirds, which are fearless in chasing much larger birds from their nests. But as a Swedish friend pointed out to me, Carl Linnaeus never saw an Eastern Kingbird in life — he saw only stuffed specimens. So did he think of it as a “king” bird because of the concealed red “crown” feathers on its head? If that were true, the bird’s tyrannical behavior would be purely a coincidence.
Actually, although Linnaeus never saw a living Eastern Kingbird, he had read about it — in Mark Catesby’s Natural History of Carolina, Florida, and the Bahama Islands. In the first volume, published in 1731, Catesby gave a perfect description of the bird that he called The Tyrant. He was a superb naturalist, and Linnaeus relied on his observations. As a result, scores of related species are called tyrants today. — Kenn Kaufman
