How did the trembler bird get its name?

These birds got their common name trembler because of their strange behavior of shaking their entire bodies in trembling motion. While singing, they cock up their tails, droop their wings, and raise them to normal position many times.

Trembling usually lasts for less than a second. The trembling frequency is different in different social contexts. They are identified as brown trembler (Cinclocerthia ruficauda) or grey trembler (Cinclocerthia gutturalis) based on the color of their plumage.
