Scientists have identified two new bird species, the bare-throated bellbird and the red-legged seriema, capable of vocalizing over 120 decibels, matching the loudness of the white bellbird. This research, published in the journal Evolution, utilized laser rangefinders to accurately measure vocal amplitude in various bird species. The study aimed to understand the factors contributing to extreme vocal loudness in birds, revealing that while larger bodies and wider beaks correlate with louder calls, other factors remain less clear.
