Listen to the Glossy Ibis
Each recording below is a short excerpt with its spectrogram, a picture of the sound. Time runs left to right and higher pitches sit higher up. Play each one, then look for the same shape in the next. Different recordings of the same bird help you learn the bird, not one clip.
What to listen for
The Glossy Ibis is described as rather quiet, giving a variety of croaks and grunts, including a hoarse breeding sound.
Many listeners write its call as “grrrr”. Treat a written sound as a memory aid; individual birds and regions vary.
What it looks like
The Glossy Ibis is a mid-sized ibis, 48–66 cm long, with an 80–105 cm wingspan. Breeding adults have reddish-brown bodies, strongly iridescent green-to-bronze or purple wing feathers, a narrow white facial band, a brownish bill, and red-brown legs.
Where to find it
It feeds in very shallow water and nests in freshwater or brackish wetlands with dense emergent vegetation, low trees, or bushes. Glossy Ibises are nomadic outside breeding, often migrating broadly, foraging in small flocks, and roosting communally at night.
