IPA: //ˈnætˌkætʃər//
KK: /ˈnætˌkætʃər/
A small bird found in North and South America, known for its bluish-gray and white feathers, long tail, and slender bill, which primarily feeds on insects.
The gnatcatcher flitted through the branches, searching for insects to eat.
Gnatcatcher → The word is formed from "gnat" (from Old English "gnæt", meaning a small flying insect) and "catcher" (from the verb "catch", meaning to capture or seize). A gnatcatcher is a bird that catches gnats, thus reflecting its behavior of capturing these small insects.
Think of a bird that 'catches' ('catcher') small flying insects called 'gnats' — that's why a gnatcatcher is known for catching gnats.
