100 Bird Species to be Endangered

Standard
Little_Dodo

The Little Dodo too is an endangered species

It is said that 100 birds on this planet are on the brink of extinction.

The main causes as because their habitats are being degraded, they are being hunted and forests are undergoing deforestation by us humans. 

Today there are many ways to prevent endangered species from undergoing extinction. Simply by increasing their population. However, it is clearly easier said than done.

Several countries like Nairobi and America have created national parks, nature reserves or wilderness areas to help prevent the extinction of animals such as the Chagos Marine Protected Area in the Indian Ocean. It is one of the largest Marine reserves on the planet.

Unfortunately, not all animals can be maintained. National parks too experience negative factors which can affect their aim of conserving the life of animals within its perimeters. Factors such as water issues and a more natural cause, climate change.

Another common way of preventing the extinction of animals is to make them populate. There are a large number of breeding programs around the world that ensure the increasing number within a species population. The Australian Zoo focuses on breeding a number of animals such as the Asian Small-clawed Otter and the Black Cockatoo.

Other methods include:

  • Habitat protection and conservation
  • Ensuring there are sufficient numbers to keep a broad gene pool
  • Keeping them on isolated islands without any predators
  • Prevention of disease within the same species

 

 Top 10 Birds in danger of extinction

 1. Giant Ibis – There are only 200 of Cambodia’s national bird left and they’re losing numbers.

2. New Caledonian Owlet-nightjar – There may not even be 50 of this rare bird, last sighted over 15 years ago.

3. Californian Condor – There are fewer than 500 of this iconic vulture.

4. Kakapo- Although there are only 125 of this charming creature, its numbers are growing thanks to conservation efforts.

5. Kagu – There are a couple of thousand of this bird, native to the island of New Caledonia, but it is flightless and vulnerable to predators.

6. Bengal Florican – There may still be around 1000 Floricans, but the south Asian bird is dying out fast.

7. Forest Owlet – There are as few as 50 of this Indian owl following the destruction of its habitat. It was thought already extinct for over a hundred years before its rediscovery in 1997.

8. Philippine Eagle – There are only two hundred left of this majestic bird of prey.

9. Christmas Island Frigate – This east Asian bird is under serious threat from the introduction of yellow crazy ants.

10. Sumatran Ground-cuckoo – There may be as few as 70 left of this Indonesian bird.

Chile’s Earthquake: 8.2

Standard

The Chilean earthquake that struck on the 1st of April 95km NW of Iquique caused a lot of stir regarding building regulations. The 8.2 mega-thrust quake was underestimated by seismologists as they expected an earthquake of a larger magnitude of around 9Mw to rupture the plates along the coastline of Northern Chile near the border of Peru. Henceforth, they believe another earthquake of a larger scale will occur and cause a massive rupture within the surface of the plate. Until then it shall remain as a seismic gap.

The quake was felt in Bolivia and Peru and was at a depth of 20.1km. Several aftershocks with an average magnitude of 4Mw to 5Mw were felt and are currently still occurring nearly on a day to day basis. The mega-thrust quake caused a tsunami on the shores of Laquique, however that too was not as large as seismologists had expected it to be as mega-thrust earthquakes produce large Tsunamis i.e. The Alaskan Tsunami in 1964. The tsunami occurred the following day at night and gathered up a height of 6.9ft.

The quake caused 7 deaths and left 200 hospitalized with 9 injured in Peru. 2500 homes were destroyed with 80,000 people displaced. Although the quake caused significant damage to many, it was said to not have caused as much damage as many had expected. Although a great number of houses were damaged many more were still standing all due to implemented building regulations.

Since Chile lies on a subduction zone, where the Nazca plate lies below the South American plate, it is constantly prone to earthquakes of all sizes. Chile’s officials aware of this fact have legislated building laws which say that buildings are meant to be made out of reinforced concrete and steel of causes a resistance towards moving ground. John Bellini, geophysicist for the US Geological Survey talked about Chile’s earthquake to CNN saying, “They’re a seismically active region of the world and they are very good at implementing their building codes similar to California.” He added, “Because of that, you would see less damage than in other places that have poorer building codes …. that’s probably one of the reasons there haven’t been as many casualties as there could have been from a magnitude earthquake of this size.”

Chile being home to the largest earthquake that ever occurred in 1960 raises concern for neighboring countries of which have neighboring fault lines. Events like the mega-thrust earthquake that occurred early this April has got countries like the US, Japan and Nicaragua taking extra precaution to ensure the safety and security of their nation by implementing building rules and guidelines and continuing to prepare and improve preparedness programs for people to follow with hopes of reducing the fatality rate in the near future. Seismologists however believe that 8Mw earthquakes may eventually occur in Japan and Indonesia due to their mobile crustal deep moving plates. In the case of moving tectonic plates it is just a matter of when.
