Context paragraphs:
Maui ‘alauahio: The Maui ʻ alauahio ("Paroreomyza montana newtoni") also known as the Maui Nui ʻ alauahio or Maui creeper, is a species of Hawaiian honeycreeper.  It is endemic to Hawaii.  The name, Maui ʻ alauahio, is somewhat misleading because the species seems to have occurred on most, if not all, parts of the ancient Maui Nui.  Its natural habitats are dry, mesic and wet forests, as well as high and low shrublands and plantations, and can be seen at Polipoli Springs State Park, and Hosmer's Grove at Haleakalā National Park.  It is threatened by habitat loss.  Their call is a loud "cheep", and their song consists of a repeated whistled phrase "whichy-wheesee-whurdy-whew".

Lana'i 'alauahio: The Lana'i 'alauahio ("Paroreomyza montana montana") was found on much of Lanai's land.  It apparently was common until the early 1900s when there appeared to have been a steep decline in birds on the island.  It was similar to the Maui alauahio and this species may have reacted similarly to its existing relative, to which it was considered conspecific.  This bird disappeared along with many others, such as the Lanai hookbill which had disappeared earlier.

Haleakalā National Park: Haleakalā National Park is a national park located on the island of Maui in the U.S. state of Hawaiʻ i.  The park covers an area of 33,265 acre , of which 19,270 acre is a wilderness area.

Gouania hillebrandii: Gouania hillebrandii (also known as hairyfruit chewstick) is an endangered species of "Gouania" that is endemic to Hawaii.  It formerly could be found on Maui, Molokaʻ i, Lānaʻ i and Kahoʻ olawe, but is today restricted to western Maui near Lahaina.  It inhabits dry forests at elevations of 244 - .  Hairyfruit chewstick is a single branched shrub with small, white flowers.

Lanai City, Hawaii: Lanai City is a census-designated place (CDP) on the island of Lanai, in Maui County, Hawaii, United States.  The population was 3,102 at the 2010 census.  Because of the island of Lanai's small population, Lanai City functions as the island's main commerce and business area.  Many of the island's restaurants and shops can be found in the town square that surrounds Dole Park and the only hospital on the island, Lanai Community Hospital, is also located close to the park.

Maui parrotbill: The Maui parrotbill or kiwikiu ("Pseudonestor xanthophrys") is a species of Hawaiian honeycreeper, that is endemic to Maui in Hawaii.  It can only be found in 50 km2 of mesic and wet forests at 1200 - on the windward slopes of Haleakalā.  This species is critically endangered, with an estimated population of only 500 individuals.  Fossil evidence indicates that the bird could at one time be seen in dry forests at elevations as low as 200 - , as well as on the island of Molokaʻ i

Dartmoor kistvaens: Dartmoor kistvaens are burial tombs or cists from the late Neolithic and early Bronze Age, i.e. from c 2500 BC to c 1500 BC.  Kistvaens have been found in many places, including Dartmoor, a 954 sqkm area of moorland in south Devon, England.  The box-like stone tombs were created when the ancient people of the area lived in hut circles.  Cists are often to be found in the centre of a cairn circle although some appear solitary which could be the result of the loss of an original slight mound.  There are over 180 known cists on Dartmoor although there could be up to 100 that remain buried underneath unexplored cairns.  In the South West there are no cists to be found on the Quantock Hills, only 2 to be found on Exmoor and 58 to be found on Bodmin Moor.  The Dartmoor cists are unique in that about 94% have the longer axis of the tomb oriented in a NW/SE direction It appears that Dartmoor cists were positioned in such a way that the deceased were facing the sun.

Oʻahu ʻalauahio: The O'ahu 'alauahio ("Paroreomyza maculata"), also known as the Oahu creeper, is a small finch-like Hawaiian honeycreeper that is endemic to the Hawaiian island of Oahu.

Lobelia hypoleuca: Lobelia hypoleuca, common names kuhiʻaikamoʻowahie, `opelu, liua, or mo`owahie, is one of several species in the genus "Lobelia" endemic to Hawaii though cultivated elsewhere.  It is found in nature on the islands of Kauaʻi, Oʻahu, Molokaʻi, Lānaʻi, Maui and Hawaiʻi.

Oʻahu ʻakepa: The Oʻahu ʻakepa ("Loxops wolstenholmei") is an extinct species of ʻakepa that was endemic to the island of Oahu.  It was commonly sighted throughout the 19th century.  This brick red Hawaiian honeycreeper was found in the mountain peaks in densely forested areas.  The females were mostly gray with a tinge of green.  The birds had a slight crossbill just like the other "Loxops" species.  It used its crossbill to open up buds in search for nectar and insects for it to eat.  Its most common haunts were the ʻōhiʻa and koa forests that were filled with the many flowers and insects that this species liked to eat.  The Oʻahu ʻakepa is one of three different species of ʻakepa that were spread by possible weather and migration.  The movement of the species stopped causing the species to break into four branches.  The first branch was the Hawaiian ʻakepa, a scarlet- red bird that lives only on the Big Island and may be the ancestor of the "Loxops" genus.  Next is the Maui ʻakepa, which was found as fossils on all the islands of Maui Nui, but was historically seen on Maui.  It is a grayish-orange bird that was the first of the ʻakepa species to disappear.  Then came the Oʻahu ʻakepa, which is a brick red color and was seen till around the 1990s when it became extinct.  The last branch was the ‘akeke‘e, a green bird that is only found on the island of Kauai.
