Ibis and Spoonbill Behaviour

Ibis and Spoonbill Behaviour Notes

The gallery features some behaviours of four ibises and one spoonbill.

Australian White Ibis is widespread in Australia occupying swamp, grassland, urban park and garden habitats. The featured birds were in Sydney’s Royal Botanic Garden and Townsville (Palmetum) Botanic Garden. Straw-necked and Glossy Ibis, also widespread in Australia, I photographed them in several the Northern Territory locations.

Royal Spoonbills are Australasian residents. I photographed them in several places in New Zealand’s South Island. They catch prey using several methods; the most distinctive is when the bird makes slow side to side movements with the open bill. Inside the spoon, papillae detect vibrations that prey makes then the birds scoop up these aquatic creatures by lifting the beak and swallowing.

Scarlet Ibis photographed at the Orange Valley mudflats in Trinidad. And flying to Trinidad’s Caroni Swamp to roost. The species occur in the north-west part of South America, and it’s a non-breeding visitor to Trinidad. The species often gather in large flocks in wetlands, marsh, swamps, and mudflats habitat.
