Nauru, a small island country located in the Pacific Ocean, is home to a vast variety of unique and beautiful bird species. Despite being just 21 square kilometers in area, Nauru offers a diverse range of habitats for these avian creatures, including lush forests, lagoons, and coral reefs.
The island’s geographic isolation and lack of predators have contributed to the evolution of a distinct range of bird species over time. The island’s endemic birds have fascinated wildlife enthusiasts and birdwatchers for generations.
With its extraordinary birdlife, Nauru is an exciting destination for anyone interested in birds and nature.
In this article, we will delve deeper into Nauru’s fascinating bird species, their characteristics, and their habitat.
1. Pacific Reef Heron

The Pacific reef heron is a species of heron found throughout Southern Asia and Oceania. It has two distinct colour morphs, one with slaty grey plumage and the other fully white.
This bird is easily identifiable by its long legs and yellow bill which are used to forage in shallow water bodies.
The sexes look alike except for minor differences such as size or body shape.
They feed on small fish, amphibians, crustaceans and molluscs that they find near reefs or mangroves where they roost during day time hours often preening their feathers if disturbed by predators like hawks or eagles .
When breeding season arrives these birds become more vocal using loud honking calls to attract mates before settling down into nests built among trees around wetlands or coastal areas.Scientific classification:

2. Procellariidae

Procellariidae is a diverse family of seabirds belonging to the bird order Procellariiformes.
These birds are commonly referred to as tubenoses and include fulmarine petrels, gadfly petrels, diving petrels, prions, and shearwaters.
They range in size from the small storm-petrel which measures around 18cm long to the giant albatross which can reach up to 3 meters in length.
Generally found near oceans or coasts where they feed on fish as well as squid and other marine life depending on species.
Many procellariids will also nest inland during breeding season before returning back out at sea for most of their lives.
Their wings have specially adapted feathers that give them incredible gliding abilities allowing them literally fly with minimal effort over vast distances across oceanic regionsScientific classification:

3. Lesser Sand Plover

The Lesser Sand Plover is a small wader bird belonging to the plover family. It has yellowish-brown upperparts and white underparts, with a distinct black band across its chest and whitish forehead.
Its wings are short but powerful, allowing it to cover large distances in search of food such as insects, worms or crustaceans found on muddy beaches or shallow lagoons near coasts.
The species prefers habitats with low vegetation like sandy deserts, coastal dunes and salt flats where they can hide among the sand grains while foraging for food during their migrations between Africa and Asia.
These birds form monogamous pairs that breed annually in springtime; nests consist of scrapes made on the ground lined with pebbles or shells carefully arranged by both parents who will vigorously defend them against predators until chicks fledge after about four weeks from hatching.Scientific classification:

The Collared Petrel is a species of seabird belonging to the Procellariidae family. It can be found in Fiji, where it breeds on Gau Island and possibly other islands, as well as potentially breeding in Vanuatu, Cook Islands and Solomon Islands.
Its plumage predominantly consists of greyish-brown colouring with white underparts and collar around its neck; this gives them their name ‘Collared’ petrels.
They are known to migrate over long distances out at sea during winter months before returning home for the summer season when they breed between August – April.
These birds feed primarily upon squid but also take small fish from surface waters or deeper depths depending on availability/seasonality.
Although not endangered yet conservation efforts need to continue so that these beautiful birds remain protected within our environment.Scientific classification:

8. Pacific Long-Tailed Cuckoo

The Pacific long-tailed cuckoo is a species of bird from the Cuculidae family. It is found only in New Zealand, where it breeds during spring and summer before migrating to various Pacific islands for its winter season.
This bird has many names such as sparrow hawk, home owl, screecher or koekoeā in Māori.
The most distinctive feature about this species are their elongated tails which can measure up to 16 cm long.
They are also brood parasites meaning they will lay eggs in other birds’ nests then rely on them to raise their young without any parental help from themselves.
Despite these traits however, they still make beautiful additions to our avian population with their melodious calls that echo through the forests each morning and night.Scientific classification:

It closely resembles the Lesser Noddy but has slightly darker feathers with dark lores instead of pale ones.
The species was first formally described in 1758, although it was previously considered to be part of Anous tenuirostris before being identified as a separate species.
They are usually found near tropical oceans or islands where they forage for food such as crustaceans, mollusks and insects during the day.
At night, they roost on trees or shrubs close to shorelines while avoiding larger predators like sea eagles.
During breeding season females lay single eggs which both parents protect until hatching takes place around four weeks later.Scientific classification:
