Its beak is hooked and pointed and its eyes are brown.
The Flesh-footed Shearwater breeds on islands in the southern hemisphere from Australia to New Zealand, South Africa, Chile, Peru and South Georgia. It’s also commonly seen off the coasts of California, Oregon, Washington and British Columbia during migration seasons. With this broad range, the species has adapted to a variety of habitats including rocky cliffs for nesting and offshore waters for feeding. Moving on from here, we will look at how the Flesh-footed Shearwater utilizes these environments in more detail.
Distribution And Habitat
The flesh-footed shearwater is found mainly in the temperate regions of the southern hemisphere, with some populations occurring as far north as Japan and Alaska. Its primary breeding range includes New Zealand, Australia, and islands off the coasts of Argentina and Chile. These birds are usually observed near coasts or offshore islands, but can also be found on pelagic trips into the open ocean.
This species is a pelagic seabird that forages for food in the waters overlying continental shelves. They often occur in large flocks when foraging, but disperse during breeding season when they return to their colonies on land to nest. In these colonies, they form dense aggregations of up to several thousand individuals. With their wide distribution and large numbers, this species is classified as least concern by the IUCN Red List. Moving forward it’s important to understand their characteristics and behavior that help them thrive in such a vast habitat range.

The flesh-footed shearwater is a medium-sized seabird that has greyish-brown plumage. Its head and neck are brown, while its underparts are white. It has a distinctive yellow bill with a dark tip and black legs and feet. The species is named for the pinkish tinge to its feet.
It actively feeds at night, when it engages in aerial dives from heights of up to five meters above the ocean’s surface. During the day, it rests on the water or on land near the shoreline. It breeds in colonies, usually laying one egg per breeding season in burrows and crevices that they dig into hillside soil and sand.
Some key characteristics of the flesh-footed shearwater include:
- A distinctive yellow bill with a dark tip
- Black legs and feet with a pinkish tinge
- Greyish-brown plumage
The flesh-footed shearwater is an active feeder that dives from heights up to five meters above the ocean’s surface. Its diet and feeding habits will be discussed in more detail below.
Diet And Feeding Habits
The Flesh-footed Shearwater is an avid sea-diver, plunging deep into the ocean in search of food. It catches its prey by swooping down and snatching them with its strong beak. Its diet consists mainly of small fish and squid, but it also eats crustaceans and some other marine life.
The seabird has a unique way of feeding; it uses its wings to ‘shear’ the surface of the water, creating a wave that stirs up prey from the depths below. This technique provides the bird with an abundant food source that it can easily access from above. Its powerful wings can lift heavy loads from depths up to 30 feet!
The Flesh-footed Shearwater’s diet is varied, allowing it to survive in a wide range of environments and provide sustenance for itself wherever it travels. With such adaptive feeding habits, this magnificent seabird will continue to thrive in its natural habitat for generations to come. Now, let’s explore how they breed and nest in their environment.
Breeding And Nesting
Flesh-footed shearwaters typically start breeding in Autumn and nest for about two months. They form colonies on islands off Australia and New Zealand, often in burrows or rock crevices. Pairs of birds use the same burrow year after year. The female lays a single egg, which is incubated by both parents for approximately fifty days. During this time, the parents take turns sitting on the egg while searching for food at sea. After hatching, the chick remains in its burrow while both parents bring it food until it’s ready to fledge.
The fledging period lasts around seventy days, during which time the chick continues to receive food from its parents until they migrate away for winter. At this point, the chick is left to fend for itself until its first migration season begins. With such a long period of parental care, flesh-footed shearwaters form strong bonds with their offspring before migrating away. This allows them to reunite with their chicks when they return each spring to breed again. Now that we know more about their breeding and nesting habits, let’s explore their migration patterns next.
Migration Patterns
The flesh-footed shearwater is a highly migratory species that breeds in colonies on the coast of Australia and New Zealand. Its wintering grounds are located in the North Pacific, where it can be found from Japan in the north to California in the south. The species undertakes an annual loop migration, traveling from its breeding sites to its wintering grounds and then back again:
| Migration Route | Months | Distance (km) |
|---|---|---|
| NZ/Aust – Japan | Aug-Sep | 5,000-7,000 |
| Japan – California | Sep-Nov | 10,000-14,000 |
| California – NZ/Aust | Dec-Feb | 12,000-17,000 |
This long distance flight requires remarkable navigational capabilities as well as great stamina and endurance. During migration they often travel in large flocks over open ocean waters. Flesh-footed shearwaters also feed while flying and will pause occasionally to rest at sea or on remote islands before continuing on their journey.
The incredible migratory pattern of flesh-footed shearwaters highlights their impressive adaptation skills and ability to survive over long distances throughout their lifecycle. Their next stop is examining their conservation status.
Conservation Status
The conservation status of the flesh-footed shearwater is considered of least concern by the International Union for Conservation of Nature (IUCN). It is found in large numbers and its population size is estimated to be between 4.9 and 5.7 million adult breeding birds. Its population has declined at a rate of roughly 3% annually, likely due to habitat loss, entanglement in fishing nets, and predation by cats and rats on the mainland.
Despite these threats, this species is still widespread throughout its range. To ensure that its populations remain healthy, there have been conservation initiatives in place to protect nesting sites from human activities, such as installing artificial nest boxes and controlling feral cats near colonies. In addition, efforts are being made to reduce plastic pollution that could potentially affect this species.
These efforts have been successful in maintaining the populations of flesh-footed shearwaters up to now. Moving on, their unique adaptations will be discussed next.
Unique Adaptations
The flesh-footed shearwater is an incredible bird, adapted to its environment in many interesting ways. Its wings are longer and more pointed than those of other species, allowing it to soar effortlessly over the ocean. Its beak is also well-adapted for catching fish and other prey from the water’s surface. Its feathers are waterproof, which helps protect it from the elements when swimming and diving underwater. The combination of these adaptations make the flesh-footed shearwater a highly successful predator and ocean traveler.
This bird also has an interesting reproductive strategy that ensures its survival despite environmental challenges or human interaction. The flesh-footed shearwater nests in colonies on islands or coastal cliffs, laying single eggs each season that are incubated by both parents.
