South rover. Like a cat, it killed all kinds of birds

In the history of the unusual southern rover, almost anything is possible, because this animal was also destroyed. for three years. He is believed to have achieved this a catAlthough some New Zealand sources are not sure that the name was invented, it is supposedly called Tibbles.

New Zealand, because this is a history from New Zealand, and it may explain a little bit how all species can disappear from the face of the Earth in a few years. Well, you can easily.

New Zealand is an isolated part of the world that broke away from the mainland of Gondwana a long time ago, and for so many years, a unique and different fauna has emerged here. Different but similar, because isolated New Zealand was subjected to the same natural processes as all other parts of the world, and one of these processes rapprochement.

What is convergence? Convergence is that completely different animal species that have remained in a similar environment for a long time begin to look similar as they find similar solutions to adapt to these conditions.

Examples include fish, dolphins, or extinct ichthyosaurs – organisms from very different groups that have very little in common but are similar in appearance because they live in a similar environment. Another example of building the wings of birds, bats and insects – unrelated animals have found a similar idea to move in the air.

In isolated New Zealand, there were almost no mammals, except for a few native bat species. Therefore, over time, some birds began to take on their role and resemble mammals – for example, the kiwi, whose feathers resemble even feathers. One such resemblance was the loss of flight skills that had been unnecessary here for millions of years. Until it is known.

It sounded when we looked at the little birds barglikam, we shrug our shoulders. They have nothing interesting – just small birds, like many around us. Nobody knows that the New Zealand leaf is the so-called basal layer of all our migratory birds. is the starting point of their evolution. It was once said that these were “the most primitive species,” but today the word “primitive” is not used in zoology, although it has never been degrading. Primitive here meant only “starting,” “with whom,” or “possessing traits lost from others,” which is extremely interesting from a natural point of view.

Barglikos in New Zealand are former relatives of shades. These birds have stopped their evolution for a while, so we can observe what migratory birds looked like in the past. Many of these animals have also lost the ability to fly – either in general or to a large extent.

The southern migratory bird probably never flew. According to the weak reports of the nineteenth century, he fled on the ground, hid in the bushes and looked for food there – small invertebrates, including insects, spiders, snails. It was one of only five non-flying species known to science. Polish birds include sparrows, magpies, tit and larks.

In New Zealand and the surrounding islands, different bird species have created separate species. The southern rover lived on the small island of Stephens, about three miles[3 km]from New Zealand, between the North and South Islands. Not much, but it is not known how the bird, which could not fly, covered these three kilometers of the sea. It is possible that his ancestors came here in a turban made of plants or wood and captured the island. They lived here peacefully. Until people come.

Little Stephens Island would not be so interesting if it did not have a strategic location between the rocks of the Cook Strait, which separates the two main islands of New Zealand. That is why in 1891 a lighthouse was built here to prevent ships sailing in these waters from falling on rocks and sandy shores. This was the verdict given to the southern rover.

A lighthouse keeper arrived on the island, and in time the crew became three lighthouse keepers with their families. There were 17 people in total. One of them was David Lyall from Scotland and his mother from the lighthouse family gave birth to him in a Scottish lighthouse. One of David Lyall’s sons insisted on taking the birds to the lighthouse, where he was bitten and brought to the door by the cat of the lighthouse keeper’s assistant. Some sources say his name is Tibbles and he slowly ran around the neighborhood. That’s why the agony of southern rovers unable to flyone by one the cat caught.

It is possible that this type of continent was also seen in New Zealand, where the mammals brought here were probably migrated by Polynesian rats who came to New Zealand with the Maori in the Middle Ages. They have inhabited the land since the 10th century, and quickly destroyed many native birds, from giant moose to small hunters.

Stephens Island was the bird’s last refuge, and it had no chance against a cat. Within a few years, he had killed all the specimens and delivered to the owners. The natural talent of one of the boys meant that we knew everything about these shades in which they were depicted Traversia lyalli. Traversation from Henry Travers, a naturalist who sent him several dead specimens, and a lyalli from the lighthouse keeper and his son.

The lighthouse was built in 1891 on Stephen Island. By 1894, there was no southern rover on it. thanks to which the species was completely destroyed one was left on the cat’s brush.
