Australian Pelican

Overview

The Australian Pelican is a large, highly social waterbird widely distributed across Australia, New Guinea, and parts of Indonesia. It is easily recognized by its predominantly white plumage, black flight feathers, and an enormous, pale pink bill that holds the record for the longest of any living bird.

Distribution & habitat

This species is highly nomadic and adaptable, inhabiting a wide variety of freshwater, estuarine, and marine wetlands. It is commonly found on lakes, rivers, swamps, coastal lagoons, and sandy shorelines. While widespread across Australia and Tasmania, it also occurs in Papua New Guinea and parts of Indonesia, with occasional sightings as a vagrant in New Zealand and various Pacific islands.

Appearance

Adults typically weigh between 4 and 13 kg with a wingspan reaching 2.3 to 2.6 meters. The most striking feature is the massive, expandable gular pouch, which can hold up to 13 liters of water and prey. During courtship, the bill and pouch undergo dramatic color changes, becoming bright red, blue, and orange. Juveniles are generally duller, with brown-tinged feathers instead of black.

Biology & behavior

Australian Pelicans are graceful, efficient fliers that often conserve energy by soaring on thermal updrafts, sometimes remaining airborne for up to 24 hours. They are gregarious birds, frequently seen roosting and foraging in large groups. While generally silent, they produce various grunts, barks, and bill-clapping sounds, particularly within their large breeding colonies.

Feeding

Primarily piscivorous, they often employ cooperative foraging strategies, working in groups to herd fish into shallow water before scooping them up. They are opportunistic feeders and may also consume crustaceans, tadpoles, and occasionally scavenge for scraps or prey on other birds.

Reproduction

Breeding occurs in large, dense colonies on the ground, often on islands. Pairs are seasonally monogamous, with both parents sharing incubation duties for 30 to 36 days. Chicks are altricial at hatching and eventually form "creches" before fledging at approximately 70 to 80 days old.
