Bare-Throated Bellbird: Birding in Brazil offers up nature’s Loudest Singer

The Bare-Throated Bellbird can be heard from miles away

Introduction

Deep in the lush rainforests of Central and South America, a bird with an unmistakable call echoes through the canopy. The bare-throated bellbird (Procnias nudicollis), known for its striking appearance and ear-splitting vocalizations, is one of nature’s most fascinating creatures. In Brazil, it’s name is the Araponga but its nickname is "campanero" or "bell-ringer," because it’s call sounds like a extremely loud bell which can be heard up to a mile away. Quite frankly, it’s one of the loudest birds on the planet.

A Distinctive Appearance

Bell Birds are fairly large but the males are particularly striking looking like something from out of this world. Found in Brazil, Argentina and Paraguay, males stand out with a snowy white plumage that contrasts sharply with their bare, turquoise-blue throat skin. This throat patch is not just for show—it inflates when the bird calls, amplifying its booming voice. Females, on the other hand, are more subdued, sporting olive-green feathers with yellowish streaks, which help them blend into their forest surroundings.

The Loudest Call in the Avian World

What truly sets the bare-throated bellbird apart is its call. On our last trip to the Brazilian Atlantic Rainforest, we heard it way before we could observe and photograph. Described as a metallic, bell-like "bonk" or "bock," the male’s vocalization is so powerful it can reach up to 125 decibels—comparable to a rock concert or a jackhammer. This call serves multiple purposes: attracting mates, establishing territory, and communicating across the dense forest.

Habitat and Range

Bare-throated bellbirds prefer humid, lowland rainforests and forest edges, where tall trees provide ideal perches for their calls. These birds are highly arboreal, rarely descending to the ground, and rely on the dense canopy for both food and protection. The two that we saw were high up in the tree but we were able to get great vantage points and the photograph above shows that it was possible to get great shots with a tele-photo. I was using a 200-500mm zoom with a 1.4 teleconverter.

Conservation Challenges

Sadly, the bare-throated bellbird is classified as Vulnerable by the IUCN due to habitat loss. The Atlantic Forest, one of the world’s most biodiverse regions, has been heavily deforested for agriculture, logging, and urban development. Only about 7-8% of the original forest remains, putting immense pressure on species like the bellbird. Conservation efforts, including protected areas and reforestation projects, are critical to ensuring the survival of this iconic bird.

Why the Bellbird Matters

The bare-throated bellbird is more than just a loud voice in the forest—it’s a symbol of the rich biodiversity of the Atlantic Forest. As a seed disperser, it plays a vital role in maintaining the health of its ecosystem. Its presence is also an indicator of forest health; where bellbirds thrive, the forest is likely intact. Protecting this species means protecting the intricate web of life that depends on these forests.

Conclusion

Birding in Brazil can bring some big surprises. The bare-throated bellbird is a testament to the wonders of nature, combining a unique appearance with a voice that commands attention. Its haunting calls remind us of the beauty and fragility of the rainforests it calls home. By supporting conservation efforts and raising awareness, we can help ensure that future generations will hear the bellbird’s song ringing through the trees. If you ever find yourself in the Atlantic Forest, listen for that unmistakable "bonk"—it’s a sound you won’t soon forget.
