Gould's Petrel

Pterodroma leucoptera

Gould's petrel, a small gadfly petrel, presents a striking contrast with its white underparts and a dark brown and grey upper side. The bird is characterized by long, narrow wings and a short, rounded tail. The head is notably dark, adorned with a white forehead and face. With a body length of 30 cm, a wingspan of 70 cm, and a weight ranging between 180–200 g, males are marginally larger than females.

Identification Tips

This species can be identified by the distinctive dark M pattern across its upper wings, a feature common to members of the subgenus Cookilaria. The robust bill, pale back, and reduced pigmentation on the underside of the wing are also notable characteristics, particularly in the New Caledonian subspecies.


Gould's petrel nests in a variety of settings, including amongst rocks and boulders, under fallen palm fronds, in hollow trunks of fallen palms, and between buttresses of fig trees. On New Caledonia, they prefer burrows in steep forested valleys.


The nominate subspecies of Gould's petrel breeds on several small islands off the New South Wales coast in Australia, with a significant presence on Cabbage Tree Island. The New Caledonian subspecies is found breeding in the central mountain chain of New Caledonia and a small colony on Raivavae in French Polynesia. Both subspecies forage in the Tasman Sea and may venture as far as the Indian Ocean and the central and eastern Pacific Ocean.


Gould's petrels are monogamous, forming long-term pair bonds and exhibiting a lengthy breeding season. They spend the majority of their lives at sea, coming ashore solely to breed. The Australian subspecies has a unique nesting habit, not using burrows but rather nesting in more exposed conditions.


The breeding season begins in mid-October when birds arrive to secure nest sites and reunite with mates. A single egg is laid between late November and early December, with incubation lasting 6–7 weeks. Chicks fledge in April to May after reaching a body mass of 160–180 g.

Similar Species

The collared petrel is sometimes considered a subspecies of Gould's petrel, and the New Caledonian petrel is occasionally elevated to species status, with all three taxa forming a superspecies complex.

Diet and Feeding

Gould's petrels feed on small cephalopods and fish. They experience substantial variation in foraging success and can go without food during lengthy incubation shifts.

Conservation Status

The Australian subspecies has seen a remarkable recovery from endangered to vulnerable, with a population increase to over 1,000 pairs. The New Caledonian subspecies, however, is estimated at 10,000 individuals and is decreasing, also classified as vulnerable due to its restricted breeding range.


The nominate subspecies faces threats from potential feral predators and wildfires, particularly during the incubation period. The New Caledonian subspecies is threatened by introduced predators such as pigs and rats, as well as light pollution in Nouméa. At sea, the specific threats to Gould's petrels remain unknown, though they are not known to be directly affected by long-line fishing operations.

I’ve had a passion of photographing birds for a long time now but have only just gotten into proper birdwatching, and this app is brilliant for those just getting started. There is a great sense of community among users and the app is very easy to use and professional. Awesome app altogether
Great App
Great app to use for logging and communicating with others who are interested in birds
Really great app
It’s easy to use and it’s fun to log the birds you notice on a walk or just in your garden. There’s a option to record the birds you see in a session which is really nice. Good excuse to stop for a while and just watch birds. I am also enjoying the information part where you can find out fact about birds from all over the world.

Very encouraging birding app
Easy to use, fun to see progress and encouraging to receive feedback from other users.
Makes you want to spot birds more
I think this app is fun. It makes you want to spot birds more so I guess in a way it encourages you to get out and about instead of sitting in front of the TV.

Great app for learning Birds
I’ve been using the app for a couple of months and love it....Someone said it’s like a real life Pokémon Go for birds. They’re not far off! It’s something that the family can do that gets you out and about. Well worth downloading no matter your age.

Clean and easy to use
Really enjoying this app, it's clean and easy to use. I love the ease of being able to add those one-off birds without starting a whole checklist. I also like the social aspect, like the parts of my Facebook I like, without the ads and junk, just birds. Can't wait to see it become more populated.
