# List of birds of Macquarie Island

This is a list of the bird species recorded on Macquarie Island. The avifauna of Macquarie Island include a total of 74 species, of which 6 have been introduced. Of these, 8 species are globally threatened.
The birds of Macquarie Island are, unsurprisingly for an isolated oceanic island, predominantly seabirds. By far the majority of the breeding species are penguins, petrels and albatrosses. However, the bird list includes many vagrants, including passerines, from New Zealand and Australia.

## Overview

Four species of penguin breed on Macquarie Island. The royal penguin has a population estimated at 850,000. There are also 100,000 breeding pairs of king penguin, the third largest such colony in the world. Gentoo and southern rockhopper penguins also breed there. In the past the penguins, mainly the royal and king penguins, were exploited for their oil, a practice which ceased in 1919.
The four breeding species of albatross are all threatened by long-line fishing when feeding away from the island, including the most numerous, the light-mantled sooty albatross with 2000 breeding pairs, and the wandering albatross, with fewer than ten pairs breeding each year.
Many species of petrel breed on Macquarie. They were adversely affected by the introduction of black rats, house mice, rabbits and cats, and the small blue petrel breeding population on the island is considered to be critically endangered. Wekas were introduced by sealers in the mid-19th century and flourished, adding to the predation threat, while the rabbits caused erosion of the hillsides. With the eradication of first the cats and the wekas, and then of the rabbits and rodents by 2014, there are signs that the breeding petrel populations are beginning to recover.
The Macquarie Island parakeet became extinct about 1891. The Macquarie Island rail, an endemic subspecies of the buff-banded rail, disappeared about the same time. The Pacific black duck population on Macquarie Island is threatened by crossbreeding with introduced mallards, a common problem on Australian and New Zealand islands.
This list's taxonomic treatment (designation and sequence of orders, families and species) and nomenclature (common and scientific names) follow the conventions of The Clements Checklist of Birds of the World, 2022 edition. The family accounts at the beginning of each heading reflect this taxonomy, as do the species counts found in each family account. Introduced and accidental species are included in the total counts for French Polynesia.
The following tags have been used to highlight several categories. The commonly occurring native species do not fall into any of these categories.
* (A) Accidental - a species that rarely or accidentally occurs on Macquarie Island
* (E) Endemic - a species that is native only to Macquarie Island
* (I) Introduced - a species introduced to Macquarie Island as a consequence, direct or indirect, of human actions

## Ducks, geese, and waterfowl

Order: Anseriformes Family: Anatidae
Anatidae includes the ducks and most duck-like waterfowl, such as geese and swans. These birds are adapted to an aquatic existence with webbed feet, flattened bills, and feathers that are excellent at shedding water due to an oily coating.
* Pacific black duck, Anas superciliosa
* Domestic mallard Anas platyrhynchos (I)
* Mallard × Pacific black duck hybrid, Anas platyrhynchos × superciliosa (I)
* Grey teal, Anas gracilis (A)

## Swifts

Order: Caprimulgiformes Family: Apodidae
Swifts are small birds which spend the majority of their lives flying. These birds have very short legs and never settle voluntarily on the ground, perching instead only on vertical surfaces. Many swifts have long swept-back wings which resemble a crescent or boomerang.
* White-throated needletail, Hirundapus caudacutus (A)
* Pacific swift, Apus pacificus (A)

## Rails, gallinules, and coots

Order: Gruiformes Family: Rallidae
Rallidae is a large family of small to medium-sized birds which includes the rails, crakes, coots and gallinules. Typically they inhabit dense vegetation in damp environments near lakes, swamps or rivers. In general they are shy and secretive birds, making them difficult to observe. Most species have strong legs and long toes which are well adapted to soft uneven surfaces. They tend to have short, rounded wings and to be weak fliers.
* Eurasian coot, Fulica atra (A)
* Baillon's crake, Zapornia pusilla (A)

## Sandpipers and allies

Order: Charadriiformes Family: Scolopacidae
Scolopacidae is a large diverse family of small to medium-sized shorebirds including the sandpipers, curlews, godwits, shanks, tattlers, woodcocks, snipes, dowitchers and phalaropes. The majority of these species eat small invertebrates picked out of the mud or soil. Variation in length of legs and bills enables multiple species to feed in the same habitat, particularly on the coast, without direct competition for food.
* Ruddy turnstone, Arenaria interpres (A)
* Latham's snipe, Gallinago hardwickii (A)

## Skuas and jaegers

Order: Charadriiformes Family: Stercorariidae
The family Stercorariidae are, in general, medium to large birds, typically with grey or brown plumage, often with white markings on the wings. They nest on the ground in temperate and arctic regions and are long-distance migrants.
* South polar skua, Stercorarius maccormicki
* Brown skua, Stercorarius antarcticus

## Gulls, terns, and skimmers

Order: Charadriiformes Family: Laridae
Laridae is a family of medium to large seabirds, the gulls, terns, and skimmers. Gulls are typically grey or white, often with black markings on the head or wings. They have stout, longish bills and webbed feet. Terns are a group of generally medium to large seabirds typically with grey or white plumage, often with black markings on the head. Most terns hunt fish by diving but some pick insects off the surface of fresh water. Terns are generally long-lived birds, with several species known to live in excess of 30 years.
