13 Inaccessible Island Rail Facts You’ll Never Forget

How many Inaccessible Island Rail facts do you know? Read on, and test your knowledge of this mysterious species!

If you want to see this bird in person, you might have to undertake a more perilous journey than you see in an adventure movie! Living on the other end of land bridges, the Inaccessible Rail is one bird that is a very difficult one to see. They live on a small, inaccessible group of islands where they had migrated 1.5 million years ago, and have stayed ever since, cut off from the world. People living in the United Kingdom may have already heard of them - called St. Helena. For so many years they saw no one, and then, their origin was discovered by humans less than 200 years ago. You might wonder, how did these land bridges come into existence at all? Scientists have theorized that the origin of this land bridge may have come from the debris of the nearby islands, which do not exist any more.

Do you want to know more about this brave bird, that migrated to these islands more than 1.5 million years ago, and continues to thrive, far away from the world? Then read on, and do not forget to check out other birds who live on islands - like the Blue Jay and Toco Toucan.

Inaccessible Island Rail Interesting Facts

What type of animal is an Inaccessible Island Rail?

The Inaccessible Island Rail (Atlantisia) is a type of bird, which lacks the ability to fly.

What class of animal does an Inaccessible Island Rail belong to?

The Inaccessible Island Rail (Atlantisia rogersi) belongs to the class of birds.

How many Inaccessible Island Rails are there in the world?

There are about 5600 Inaccessible Island Rail Atlantisia birds in the world.

Where does an Inaccessible Island Rail live?

The world's smallest flightless bird, the Inaccessible Island Rail Atlantisia, can only be located on Inaccessible Island in the Tristan Archipelago.

What is an Inaccessible Island Rail's habitat?

On Inaccessible Island, the rail can be found in practically all habitats and at all elevations. Its densest populations are found in tussock grass fields. This habitat can be found near the sea and on the steep cliffs that cover the majority of the island. The Inaccessible Island rail Atlantisia can also be spotted in the central plateau's upland fern-bush and island woodland, and it is the world's smallest extant flightless bird.

Who do Inaccessible Island Rails live with?

These species are solitary by nature.

How long does an Inaccessible Island Rail live?

The Inaccessible Island Rail Atlantisia bird lives for about six years in favorable conditions.

How do they reproduce?

The Inaccessible Island Rail bird is a type of seasonal breeder who lays her eggs from October to January months. They are monogamous by nature and form lifelong pair bonds. The nests are hidden among the tussock grass and ferns. The structure of nests is dome-like and pear/oval-shaped. Mostly, the nests are entirely constructed from the same material. The openings are close to the narrow end of the nests, connected by a tunnel or track which goes roughly half a meter away. Two eggs are laid in a clutch, and the color of the eggs is milky gray-white with brown-rufous markings. The male and female both incubate the clutch, since, in the observations made, the male bird incubates for a longer period of time. A couple carries food to their incubating partner, which is eaten either on the nest or near to it. It takes between 23-32 hours for the eggs to hatch.

What is their conservation status?

The IUCN Red List rated the Island Rail (Atlantisia rogersi) as a Vulnerable species, due to their vulnerability to extinction.

Inaccessible Island Rail Fun Facts

What do Inaccessible Island Rails look like?

The Inaccessible Island Rail (Atlantisia rogersi) male birds are darker chestnut-brown above as well as dark gray underneath, with deteriorated white barring on the belly and both flanks, with red-eye. The physical structure of females is almost the same as the male birds but has a paler gray underbelly and a light brown wash. These species have a short black bill that matches the length of its head. The Inaccessible Island rail's feathers seem to be almost hair-like.

Inaccessible Island Rail facts are fun to know!

How cute are they?

The Island Rail (Atlantisia rogersi) is possibly the coolest bird. These rail species from the rail family (genus: Laterallus ) with hair-like feathers, black bill, red-eye, and brown plumage are small and cute birds.

How do they communicate?

The Inaccessible Island Rail birds are a very loud species that call a lot. This could be due to the species' thick forests, which makes calls the effective ways to communicate, and couple and family members interact effectively while feeding. A long trill can be used when pair meet and when challenging a competitor.

How big is an Inaccessible Island Rail?

The average length of Island Rail (Atlantisia rogersi), of the genus Rallidae, is 5.1–6.1 in. While a relative of these species, the Dot Winged crake's length is 5.5-5.9 in. Regular Rail birds measure 4-18 in long. Island Rallidae and its relative belong to the same family.

How fast can an Inaccessible Island Rail fly?

The smallest extant flightless bird, endemic of the Inaccessible Island in the Tristan archipelago, has very small, weak, and reduced wings. This is because these birds (of the family Rallidae) don't have the ability to fly.

How much does an Inaccessible Island Rail weigh?

The average weight of male extant flightless birds is 1.43 oz and for females, the weight is 1.3 oz.

What are their male and female names of the species?

There is not any specific name for male and female species of Island Rail, Atlantisia rogersi,(of the class Aves).

What would you call a baby Inaccessible Island Rail?

A baby Inaccessible Island Rail (genus Laterallus) doesn't have any special name.

What do they eat?

Amphipods, earthworms, mites, isopods, and a range of organisms such as flies, beetles, caterpillars, and moths are among the invertebrates they eat. Centipedes are also eaten, and a newly added species of centipede is a staple in their diet. They can eat the berries including the seeds of the dock, in addition to invertebrate prey.

Are they dangerous?

The world's smallest flightless bird, Atlantisia rogersi species is not dangerous for humans.

Would they make a good pet?

This smallest extant flightless bird is on the vulnerable list and likes to live a solitary life. So these species of the Inaccessible Island in the Tristan archipelago would not be a good pet.

Did you know...

The world's tiniest, still-living, extant flightless bird can only be located on Inaccessible Island, a remote island in the South Atlantic Ocean's Tristan archipelago (UK residents will recognize it as St. Helena). Due to being endemic to Inaccessible Island, this bird got its name. Scientists first reported the bird in Inaccessible Island, which is  2,175 mi from South American areas and 1,740 mi from South Africa. The origin of the Inaccessible Island rail was really a long-standing secret due to the unavailability of sufficient data. Just before plate tectonics theory, scientists speculated that the bird had traveled to this island over a submerged land bridge.

According to scientists, the predecessor of this bird arrived on the island from South America around 1.5 million years ago. They may have reached there with the help of wings or floating on debris material. This species was first identified by British surgeon Percy Lowe, who was then in charge of the British Museum ornithology collections. Lowe labeled this species rogersi from the first person to collect samples, H M C  Rogers, a chaplain on the neighboring island of Tristan da Cunha.

Are Inaccessible Island Rails endangered?

These Rail birds, that don't have the ability to fly, are vulnerable to extinction. The main threats for this species are feral cats, house mice, and brown rats. Study shows that these predators are not native of the islands but they belong to neighboring Tristan da Cunha or Nightingale island. Through other visiting boats or fishing vessels these predators could reach the island home of Inaccessible Rail. The Tristan da Cunha Island Council announced the Inaccessive Island as a nature reserve and now access to this place is prohibited. This species future can be secured by increasing training on biosecurity to the local communities.

What is the difference between an Inaccessible Island Rail and a regular Rail bird?

This bird (found in Tristan da Cunha) has black-colored bills and feet with brownish hair-like feathers and has red eyes. The Inaccessible Island rail is territorial in nature. Regular Rail birds are mostly marsh birds with chicken-like shapes, short tails, and rounded wings, and have huge feet. These birds are secretive by nature.
