Let's learn more about the Flesh-footed Shearwater, a bird that continues to fascinate and inspire.

Flesh-footed Shearwater's Life Cycle

life cycle of shearwater

The life cycle of the Flesh-footed Shearwater begins on the nesting grounds in New Zealand, where they form colonies on islands such as the Chickens and Mercury groups, Ohinau and Karewa Islands. The population count, based on recent surveys, indicates less than 12,000 pairs remain.

The birds then migrate to the North Pacific Ocean, spending the northern summer in the seas off eastern Japan. These seabirds, medium to large in size, are characterized by their dark coloring and long, powerful hooked bills.

Threats to the Flesh-footed Shearwater include plastics ingestion, exposure to land-based pollutants, increased levels of radioactivity, and the risk of being caught in commercial and recreational fisheries.

This life cycle information is key to understanding the conservation needs for this unique species.

Distinctive Bill Coloration

The Flesh-footed Shearwater seabird has a distinctive bill coloration. This feature is characterized by a rich, dark chocolate hue, making it stand out. The bill of the bird is entirely dark chocolate in color, exhibiting a dark-tipped pink bill.

The bill shape and pattern of the Flesh-footed Shearwater are unique, being shorter-tailed and stockier compared to the dark-morph Wedge-tailed Shearwater. The bill of the Flesh-footed Shearwater is significantly different from other dark Procellaria petrels, such as the Parkinsons.

The bill coloration, a uniform dark brown, imparts a striking appearance to the bird. This feature distinguishes the Flesh-footed Shearwater from other seabirds, such as the Sooty Shearwater. The Flesh-footed Shearwater's bill coloration, along with its size and shape resembling the Pink-footed Shearwater, adds a unique allure to the bird.

Anatomy and physiology

The Flesh-footed Shearwater showcases an intriguing combination of anatomical and physiological characteristics that enable them to survive and thrive in their oceanic habitat.

The Flesh-footed Shearwater is characterized by its medium to large size and a powerful hooked bill. This bill is thick and pale pink at the base which sets it apart from other dark Procellaria petrels. The bird's long, relatively broad wings and a long pointed tail contribute to its ability to soar and glide effortlessly through the air.

The Flesh-footed Shearwater displays a uniformly dark brown plumage that contrasts sharply with its pink-white bill and white-flesh colored legs. The distinctive foot color, similar to the base of the bill, is a key identification feature of this species.

Despite their dark plumage making them difficult to see in the field, the unique shape of their bill and the color of their feet are distinguishing features. These features not only identify the Flesh-footed Shearwater but also highlight the fascinating interplay of anatomy and physiology within this species.

Colorful Feather Patterns

The Flesh-footed Shearwater exhibits vibrant and intricate feather patterns. Its feathers are a deep, dark chocolate color, contrasting strikingly with its dark-tipped pink bill. The bird's overall shape and unique coloration make it distinguishable from other species.

Species flags in eBird-powered field guide apps often help differentiate the Flesh-footed Shearwater from other introduced species on the West Coast of North America. The bird's foot color, also dark chocolate, serves as another identification feature.

The Flesh-footed Shearwater breeds on islands off the coast of southern Australia and northern New Zealand. It is considered a native species in these regions, but also occurs in other parts of the world as an introduced species. The West Coast of North America's official eBird totals include records of what were once considered exotic populations, due to natural vagrancy or captive provenance. Bird records committees play a vital role in differentiating between native and introduced populations. The colorful feather patterns of the Flesh-footed Shearwater contribute to its identification and conservation efforts.

Parental Care

The Flesh-footed Shearwater displays a strong commitment to parental care. This is evident in the bird's active involvement in the incubation of eggs and the nurturing of its offspring. The bird's parental care can be broken down into three main tasks: incubation, feeding, and nurturing.

The Flesh-footed Shearwater adheres to a bi-parental care system, signifying that both parents share responsibilities. This involves both the mother and father bird taking part in the incubation of the egg. They alternate roles, ensuring the egg is always cared for during their long breeding cycle.

The feeding responsibility is also shared between the two parents. Both mother and father bird take on the task of finding food for their chick. They often travel great distances over the open sea to accomplish this. The feeding process is done through regurgitation, with both parents providing food for the chick in this manner.

The nurturing of the chick is the final aspect of the Flesh-footed Shearwater's parental duties. The parents look after the chick until it is ready to fledge and become independent. The survival and well-being of their offspring is a testament to the dedication of the Flesh-footed Shearwater to parental care.

Breeding Grounds

The breeding grounds of the Flesh-footed Shearwater are primarily located among the islands off the southern coast of Australia and the northern coast of New Zealand. These breeding grounds function as sanctuaries for the seabirds, serving as the main sites for their nesting and the rearing of their young.

The birds favor remote islands for their colonies, where they find appropriate nesting habitats. The plentiful population of the Flesh-footed Shearwater in these locations bears witness to the successful conservation efforts aimed at preserving their breeding grounds.

The Threatened Species Occasional Publication and the Action Plan for Australian Birds have underscored the need to protect these colonies, recognizing their vital role in maintaining the species' population. Measures are in place to mitigate threats, such as pelagic longline fishing and habitat degradation, to ensure the preservation of the Flesh-footed Shearwater breeding grounds for the benefit of future generations.

Unique Mating Call Pattern

The Flesh-footed Shearwater is a seabird species native to Northern New Zealand and Lord Howe Island. It is distinguished by its unique mating call pattern. This seabird's mating call is loud, undulating, and raucous, akin to cats in a brawl. The vocalization only occurs on land, making it a silent traveler over the sea. Despite their dark chocolate plumage, which often makes them hard to spot, the distinctive call of the Flesh-footed Shearwater greatly aids researchers and birdwatchers in their identification.

Hence, the unique mating call pattern of the Flesh-footed Shearwater contributes significantly to the enchantment and mystery surrounding this Pacific seabird.

Conservation

protecting our natural resources

The main concern revolves around the conservation of the Flesh-footed Shearwater, a unique seabird species native to Northern New Zealand and Lord Howe Island. The species is vulnerable and its survival directly depends on conservation efforts designed to mitigate various threats.

The limited distribution of the Flesh-footed Shearwater necessitates the implementation of effective conservation strategies.

Pollution and climate change are major threats that can gravely impact the population abundance of these seabirds.
