Key Questions Answered
Scientists have recently identified the Bare-throated Bellbird and the Red-legged Seriema as the two new bird species with the loudest calls in the world. Their scientific names are Procnias nudicollis and Cariama cristata, and their calls surpass 120 decibels.
The sound level of these two birds goes beyond 120 decibels, which is louder than standing near a chainsaw or a jackhammer. This extreme noise level can make human ears go numb and echoes easily for miles in the forest.
The loudest birds usually have large bodies equipped with heavy and strong muscles that help compress air very quickly. Additionally, they have wide beaks that function like a trumpet or musical instrument to greatly amplify the sound.
