WWF works to sustain the natural world for the benefit of people and wildlife, collaborating with partners from local to global levels in nearly 100 countries.
The white bellbird, native to the Amazon rain forest, has the loudest recorded call of any bird: 125 decibels, or roughly as loud as a rock concert. It uses this call not for long-distance communication or to intimidate predators but to woo potential mates. This pigeon-sized bird is no Frank Sinatra, though. Its hair-raising song sounds more like an emergency alarm than a lover’s warble. (Trust us: Look it up.)
SIZE About 11" long
NOISE LEVEL CHART (in decibels)
Researchers have found that male white bellbirds sing loudest around females, likely in attempts to attract a partner. When a female perches nearby, the male begins its song, then pivots to face her head-on and belts his most ear-splitting note. Females may favor the loudest males.
Unlike males, females don’t have wattles or a mating call. In fact, they barely make any noise at all.
