Biologists measure call loudness across 123 bird species

Original: 🐦 NEW: Biologists measured call amplitude in 123 bird species across # Massachusetts and # Brazil using # golf rangefind

Biologists have measured call amplitude in 123 bird species across Massachusetts and Brazil, using golf rangefinders paired with sound meters to estimate how loudly each bird vocalises. The work adds first-time loudness data for 113 species, with volumes spanning 58 decibels, from hummingbirds near conversational levels up to far louder calls. The findings give researchers a new baseline for studying animal communication.

Why now: A newly published study offers first-ever loudness measurements for over a hundred bird species, an unusual and novel dataset.
