Ever wonder what the loudest bird on Earth is? The outrageous Bare-throated Bellbird (Procnias nudicollis) is certainly a top contender! While hiking up the Green Trail here at REGUA, singing males can be heard from over a kilometre away.
The call each male belts from his featherless blue-skinned throat sounds like a mallet striking an iron pipe, and echoes down the valley in rhythmic series. As we climb higher up the mountain trail, the boinks and bonks of competing males get louder and louder, but we can often only catch glimpses of them perched high in treetops.
Today, volunteer bird guide Bobby found our lucky visitor group, front row seats to an ear-splitting performance by a young male singing close beneath the canopy. Bare-throated Bellbirds are endemic to the Atlantic Forest, found nowhere else on Earth. These large, fruit-loving passerines perform crucial seed dispersing services for many lowland and montane trees. Unfortunately, drastic logging of the Atlantic Forest for development, combined with illegal poaching for the caged-bird trade, has led to declining populations of this spectacular species and a Vulnerable designation by IUCN. But thanks to REGUA, the forest home of these contending males along the Green Trail is safe into the future. And they can return the favor by dispersing their favorite fruit trees throughout the reserve, helping the forest to grow!
