New Zealand’s Rarest Mainland Forest Bird Is Having an ‘Epic’ Breeding Season
Up until 25 years ago, New Zealand's orange-fronted parakeet, or kākāriki karaka, was believed to be extinct. Now, it's having one of its best breeding seasons in decades, NPR reported Thursday.
At least 150 kākāriki karaka chicks have been born in the wild this season, New Zealand Minister of Conservation Eugenie Sage said in a statement Wednesday, potentially doubling the population of New Zealand's rarest mainland forest bird, which is estimated to be between 100 and 300.
"It is great news that this year there are more than three times the number of nests compared to previous years," Sage said. "This year's epic breeding provides a much-needed boost to the kākāriki karaka population."

The New Zealand Department of Conservation (DOC) said it had found 31 nests in Canterbury so far this year, and that the breeding season was not yet over.
The bird, also known as Malherbe's Parakeet, scientific name Cyanoramphus malherbi, is considered critically endangered by the International Union for Conservation of Nature (IUCN). The leading threat to the endangered species are the stoats and rats that were introduced to New Zealand, which prey on the birds. The parakeets are also threatened by resource use and habitat loss. They require beech trees old enough to form cavities suitable for nests. But beech trees tend to be harvested before these holes have time to form, meaning the birds are unlikely to settle in managed forests, the IUCN concluded.
This year's population boost is also related to the beech tree: 2019's mast of beech seeds is the biggest in more than 40 years.
"There has been so much seed on the beech trees the birds just keep on breeding with some parakeet pairs onto their fifth clutch of eggs," Sage said. "When there's no beech mast they typically have just one or two clutches."
But the mast is also expected to increase the population of the bird's imported predators.
"Over the coming months, DOC will be focused on protecting the critically endangered kākāriki karaka from increased numbers of rats, stoats and feral cats," Sage said.
The birds once lived across New Zealand, BBC News reported, but during the 20th century, their numbers declined to the point where they were believed extinct. However, in 1993 they were re-discovered in the country's Canterbury region.
Conservation groups have bred more than 500 of the parakeets since 2003 and released them into Canterbury, as well as onto predator-free islands, DOC said.
This year, 62 kākāriki karaka were released into the South Branch of Canterbury's Hurunui River. Most of the introduced birds survived and are getting ready to breed.

The 2020 hurricane season is now expected to be the most active since at least the early 1980s, meteorologists at Colorado State University, a standard bearer for seasonal hurricane predictions, announced Wednesday.
Three years ago, scientists predicted it would happen. Now, new NASA satellite imagery confirms it's true: two ice caps in Canada's Nunavut province have disappeared completely, providing more visual evidence of the rapid warming happening near the poles, as CTV News in Canada reported.

Lebanese Prime Minister Hassan Diab says he believes Tuesday's explosion in Beirut could have been caused by large quantities of ammonium nitrate stored in the port.
What Is Ammonium Nitrate?<p>Ammonium nitrate is a white crystalline salt that can be fairly cheaply produced from ammonia and nitric acid. It is soluble and often used as fertilizer, as nitrogen is needed for healthy plant development.</p><p>Ammonium nitrate in its pure form is not dangerous. It is, however, heat sensitive. At 32.2 degrees Celsius (89.96 degrees Fahrenheit), ammonium nitrate changes its atomic structure, which in turn changes its chemical properties.</p><p>When large quantities of ammonium nitrate are stored in one place, heat is generated. If the amount is sufficiently vast, it can cause the chemical to ignite. Once a temperature of 170 C is reached, ammonium nitrate starts breaking down, emitting nitrous oxide, better known as laughing gas. Any sudden ignition causes ammonium nitrate to decompose directly into water, nitrogen and oxygen, which explains the enormous explosive power of the salt.</p>
Deadly Disasters<p>As ammonium nitrate is a highly explosive chemical, many countries strictly regulate its use. Over the past 100 years, there have been several disasters involving the chemical.</p><p>In 1921, for example, a massive blast occurred at a BASF chemical plant in Ludwigshafen in the German state of Rhineland-Palatinate. About 400 metric tons of a mixture of ammonium sulfate and ammonium nitrate exploded, killing 559 people and injuring 1,977. The plant was largely destroyed in the blast, which could be heard as far away as Munich, some 300 kilometers (186 miles) distant.</p><p>In 2015, explosions caused by ammonium nitrate ripped through the <a href="https://www.dw.com/en/china-convicts-dozens-for-last-years-giant-explosions-in-tianjin/a-36324321" target="_blank">Chinese port city of Tianjin</a>. Eight hundred metric tons of the chemical were said to have been stored along with other substances in a warehouse for hazardous materials. The blasts killed 173 people and destroyed an entire city district.</p><p>Two years earlier, in 2013, an ammonium nitrate explosion occurred at the West Fertilizer Company site in Texas, killing 14 people. And in 2001, 31 people died in Toulouse, France, in an explosion caused by the chemical.</p>
Terrorist Favorite<p>In Germany, the purchase and use of ammonium nitrate is regulated by the explosives act. This is because the cheap, highly explosive and relatively easily obtainable material has in the past been used by terrorists to carry out attacks.</p><p>For example, in 1995, U.S. conspiracy theorist and gun enthusiast Timothy McVeigh used a mixture of ammonium nitrate and other substances to bomb the Alfred P. Murrah Federal Building in Oklahoma City. Norwegian far-right extremist Anders Behring Breivik also used ammonium nitrate in a car bomb attack in Oslo in 2011.</p>

Most Americans know about the Dietary Guidelines for Americans primarily through their colorful representations: the original food pyramid, which a few years ago morphed into MyPlate. The guidelines represent the government mothering us to choose the healthiest vegetables, grains, sources of protein, and desserts, and to eat them in the healthiest portions.
As innocuous as the food pyramid and MyPlate seem, they are actually a matter of life and death.
