Except for feathers and eggs, the Stephens Island Wren bore more resemblance to a mouse than a bird. Cats can “go wild” within a generation. He envisioned spending long nights deep in thought, identifying specimens of plants, insects, and birds, burning through large amounts of paraffin oil—all while supporting his family. As one story goes, a cat, possibly named Tibbles, made it to Stephens Island and was allowed to roam free. The wren population on Stephens Island was, in fact, the last remnant of a species that once lived throughout New Zealand. Being a lighthouse keeper in the late 1800s was not an easy job, although the primary duty—keeping the light burning bright and clean—was straightforward, requiring a constant trimming of the wick to maximize the flame and reduce the smoke. If an unrelated adult male is not around, siblings will eventually mate with one another, or offspring will mate with their mother. Equipped with large feet and a short tail, it ran low to the ground among the shoreline rocks or jumped from branch to branch through thick tangles of knotty shrubs. While the Lyall’s wren was widespread in all of New Zealand prehistorically, it became extinct when the Maori settled on the island and introduced the Polynesian rat and other non-native animals which preyed on the birds. Due to World War 1, and with the invention of the guns and the other arms, it became much easier to hunt such ostriches and this lead to the extinction of the birds.

Like other small land-masses surrounded by water that have emerged over different time frames—such as the Galápagos, Hawaiian, and Caribbean island archipelagos—New Zealand provides a dramatic example of how the temporal process of species diverging and adapting to their local environment can be seen from place to place. The rock wren is still extant, not extinct.

In 1598, Dutch sailors came across these flightless birds on the island and immediately saw its potential for meat, as they were starving by the time they reached land. Given the biogeographic history of New Zealand, some populations of the Stephens Island Wren likely were isolated from other populations for millions of years, making this scenario quite plausible. He was blindly focused on getting to his new post on the largely unexplored and uninhabited island, a place where he could finally pursue his passions. According to the myth, this murderous feline brought the carcasses to his owner, David Lyall, who was interested in natural history, and then brought the new species to the attention of the scientific world in mid 1894. In other words, in the space of 12 months, the Stephen Island Wren was discovered and simultaneously declared extinct because of some jerk cat called Mr. Tibbles. Typically, it is the combination of morphological and/or genetic differences that are used to delineate different species. The cat had eaten the first and last of the species, and all the others in between. The species’ size, color, and shape changed at varying speeds over time, sometimes at a glacial pace, sometimes more rapidly. These are the traits that develop largely through genetic mutations and/or long periods of reproductive isolation, such as might occur on islands or on the opposite sides of mountain ranges or rivers. The disputed subspecies orii, the Daito wren, became extinct around 1940 – if it was indeed a valid taxon and not merely based on an anomaly. A story told over and over again, all over the planet, for thousands, hundreds of thousands, even hundreds of millions of years.

Several hundred people had lost their lives in three major shipwrecks in the mid-1800s in New Zealand, so lighthouse construction had become a priority. Many sailors at the time could not swim and, ironically, hated water—especially the frigid subantarctic waters enveloping the southern islands of New Zealand. They are ambush predators, sitting for long periods, motionless and quiet, waiting for the right time to pounce. Post Mar 03, 2015 #1 2015-03-03T14:34.

A unique song, a lost language never recorded, and one now permanently silent. But this species, like all species of plants and animals, changed at a pace to fit the landscape—the biological, climatic, and geological landscape—all through the process of natural selection. The dodo bird was discovered in 1591 in Mauritius by Portuguese sailors. It is not known exactly when this wren blinked off the earth for good.

Gigantopithecus -- the closest Nature ever came to producing a real King Kong -- weighed five times as much as an adult man and probably stood three metres (nine feet) tall, according to sketchy estimates. It could have been within a single year, but it was certainly not much more than a few years after Lyall and the other lighthouse keepers first made their way to Stephens Island that the wren disappeared. Because whole specimens of similar wrens from other regions of New Zealand do not exist in collections, there is no way to know whether these other populations were actually the same species as those preserved from Stephens Island. It may be that through the destruction of habitats, combined with the spread of cats and rats, populations of this flightless bird had shriveled, and the isolated inhospitable Stephens Island served as a last refuge for the only remnant population. As a kitten she was likely as silly and entertaining as any yarn ball–chasing kitten today. A collar and bell works pretty well to keep even a healthy young outdoor cat from killing birds.

In fact, the Stephens Island wren was discovered and then became extinct within the space of a year, the Equally plausible is the idea that fossil wrens found on other islands of New Zealand with physical features similar to the Stephens Island Wren were actually different species. Certainly all her progeny were feral. It was like solving a puzzle, revealing something previously unknown, and providing order to a natural landscape that appeared to be in disorder. Anglo explorations of the island began in the 1870s, led by New Zealand maritime officials who had determined that a lighthouse installation was needed to ensure safe passage through nearby channels. Small as it was, the island’s forested summit held a diversity of vertebrates and invertebrates that even then was unique. Tibbles, along with her litter in utero, was the first to come ashore, early in 1894. 771 23 1.
