THE LORD HOWE
BOOBOOK/MOREPORK
1. The Lord Howe boobook, Ninox novaeseelandiae albaria, was the smallest subspecies of the morepork family of true owls. The name ‘boobook’ means hawk-owl. Some references show the Lord Howe boobook as a distinct species, but most now label it as one of 14 subspecies. 2. This small owl measured 11 - 13 inches tall and had spotted plumage. 3. According to measurements taken of museum specimens, the Lord Howe boobook was smaller than the boobook of mainland Australia but larger than those found in New Zealand or Norfolk Island. 4. Higgins described it as having, "an indistinct X-shaped marking; the upperparts were pale reddish brown, concolorous with the head, with white spots; and the underparts and upper wings were pale rufous brown with small white spots. Its bill was dark slate grey, its eyes were golden yellow and its legs and feet were greenish yellow.” 5. Nothing is known about its social structure, but other boobooks live singly, in pairs, or in small family groups during the summer months. This may have held true for the Lord Howe boobook. 6. It inhabited the native forests and the area around settlements. 7. The Lord Howe boobook’s last reported calls came from the 1950’s, and specimens can be found in the Australia Museum. 8. In 2019, a dead owl was found on Lord Howe sparking excitement that its boobook was not extinct, but DNA testing showed that it was actually a Tasmanian boobook that was far from home, perhaps blown off course by a “significant weather system” that had passed through the area. It was the first boobook found on Lord Howe Island in over 50 years.

EXTINCTION DATE
1950's
Lord Howe Island is a unique habitat found in the middle of the Tasman Sea and is part of New South Wales, Australia. Lord Howe Island’s extinction history runs parallel to so many other unique islands around the world. It has been a World Heritage Site for over 36 years and has many unique species that can only be found on Lord Howe Island. It had 113 unique plants, approximately 800 insect species, not to mention the many bird species that have gone extinct there. As people came to Lord Howe Island on the routes from Australia to Norfolk Island, then up to the Solomon Islands, the people used the island to hunt and gather supplies. The Lord Howe swamphen and pigeon were so tame they were “easily caught by hand”. They were the first island species to go extinct. In 1834, the British established a settlement on Lord Howe Island. In 1850’s scientists came to the island to catalog its unique species. Lord Howe Island became a tourist destination because of its unique plants, wildlife, and location. As people came to the island more often, invasive species were inadvertently brought with them. According to the Lord Howe Island Rodent Eradication Project, the house mouse was brought to the island in 1860. On June 15, 1918 the steamship SS Makambo ran aground and released black rats on Lord Howe Island when the crew threw crates of bananas overboard to lessen the ship’s weight. The rats had been hiding in these crates and floated to the island. This accidental event had devastating consequences on Lord Howe Island. The Lord Howe boobook’s fate was one of those creatures that was affected by this invader. The rats began eating the farmer’s crops which hurt the island’s economy. To combat the rat invasion, Tasmanian masked owls were introduced to the island from 1922 - 1930. It was thought these predators would help control the rats, but it had very little impact. Instead, the invasive owls began eating native birds. Seven bird species, including the Lord Howe boobook, went extinct as a result of the black rats and owls. It is thought that the boobook could not compete against the larger Tasmanian masked owl, and its numbers plummeted. A similar situation is taking place in the Pacific Northwest in America where the native spotted owls are in steep decline since the barred owl entered that area. In the U.S. the government is calling for 500,000 barred owls to be killed over the next few years to make room for the native spotted owls. The last Lord Howe boobook was heard in the 1950’s, but no one knows the exact date of its extinction. Although Jurassic Park is fiction, scientists are working on several de-extinction projects. In fact, in 2003 scientists did bring back the extinct Pyrenean ibex, a type of wild goat, for 7 minutes before it died, showing de-extinction is possible. The Lord Howe boobook might be a candidate. Scientists would potentially use DNA from museum specimens at the Australia Museum. While it could possibly be a candidate for de-extinction, would it be able to survive on Lord Howe Island today? Much has been done in Lord Howe to promote conservation and fight the invaders. Groups like the Lord Howe Island Rodent Eradication Project, are seeking to find ways to eliminate rats and mice from the island. Here is a quote from the Lord Howe Rodent Eradication Project about the impact of rodents on the island and what they are working on to help the Lord Howe ecosystem. “The presence of exotic rodents on islands is one of the greatest causes of species extinction in the world. Rats have already been implicated in the extinction of five endemic bird species, at least 13 species of endemic invertebrates, and two plant species on LHI. Rodents are also a recognised threat to at least 13 other bird species, 2 reptiles, 51 plant species, 12 vegetation communities, and 7 species of threatened invertebrates on the Island. Seven of these species are listed as “Critically Endangered” under NSW and Commonwealth legislation. These programs complement significant achievements to date including the eradication of cats and pigs in the 1980’s, feral goats in 1999, and Myrtle Rust in 2018, a world-first. The Protecting Paradise Program was the Gold winner of the 2018 Banksia Sustainability Awards and the 2018 NSW Green Globe Awards in the Natural Environment and Regional Sustainability categories. After more than 15 years of detailed research and planning, final implementation of the Rodent Eradication Project (REP) is almost complete.” Native birds were captured while rat poison was spread throughout the habitat. Once the rats had been poisoned, the captured birds were released back into the wild. These efforts worked well. Dogs were used to eliminate any remaining rats from the island. The last reported rat on Lord Howe Island was in August of 2022. If the Lord Howe boobook was reintroduced to Lord Howe Island, could it again thrive there? Maybe. Consider this. The Lord Howe woodhen population had been down to 15 individuals in 1980, but today there are over 800 birds.
NEW STORY
Who am I? I am Book, the Lord Howe boobook or morepork. I am a small owl, and owls are stereotyped as being wise, as are people who read books. Did I overcomplicate my name choice? I was from Lord Howe Island which was nicknamed “Treasure Island'' because of its pristine beauty. I am part of the TIC, Treasure Islanders Club, here. It wasn’t until 1918, that the TIC’s membership soared. Sorry. I mean, it increased dramatically. The term ‘soar’ can be insensitive to flightless birds. On June 15, 1918 the steamship S.S. Makambo ran aground and accidentally released black rats on Lord Howe Island. As the steamship began to sink, the crew threw crates of bananas overboard to lessen the ship’s weight. The rats had been hiding in these crates and floated to the island. This accidental event had devastating consequences on Lord Howe Island. Since that one event, the TIC has added five birds, thirteen invertebrates, and two plants.
