Mesembrinibis – Green ibis

At first glance, especially in the dim light of a rainforest, it might look like just another dark wading bird—but get a closer look, especially when the sun hits just right, and you’ll see where it gets its name. This ibis has a sleek body covered in dark, glossy feathers with a greenish and bronze shimmer, almost like it’s wearing metallic armor. Found in the wetlands, swamps, and tropical forests of Central and South America, the Green Ibis is one of the more mysterious and lesser-known members of the ibis family.

Unlike its flashier cousins, like the Scarlet Ibis, the Green Ibis tends to keep a low profile. It prefers solitary or small group living and is most active during the early morning or late afternoon. It’s a shy, quiet bird, often staying close to cover and avoiding open water. You’ll more likely hear it before you see it—its call is a loud, harsh “haaah” or croaky grunt, which it often makes while flying or during the rainy season when it’s more vocal.

One of the coolest things about the Green Ibis is its foraging technique. It uses its long, curved bill to probe mud and shallow water in search of insects, worms, small fish, and amphibians. It moves slowly and methodically, often in shadowy areas, making it easy to miss. That curved bill acts like a natural tongs, perfect for grabbing slippery snacks buried beneath the surface. Despite its secretive nature, the Green Ibis plays a key role in controlling insect populations in its habitat.
