The Hawaiian crow or ʻalalā is a species of bird in the crow family, Corvidae, that is currently extinct in the wild, though reintroduction programs are underway. It is about the size of the carrion crow at 48–50 cm (19–20 in) in length, but with more rounded wings and a much thicker bill. It has soft, brownish-black plumage and long, bristly throat feathers; the feet, legs, and bill are black. Today, the Hawaiian crow is considered the most endangered of the family Corvidae. They are recorded to have lived up to 18 years in the wild, and 28 years in captivity. Some Native Hawaiians consider the Hawaiian crow an ʻaumakua.
Located about 2300 miles (3680 km) from the nearest continental shore, the Hawaiian Islands are the most isolated group of islands on the planet. The plant and animal life of the Hawaiian archipelago is the result of early, very infrequent colonizations of arriving species and the slow evolution of those species—in isolation from the rest of the world's flora and fauna—over a period of at least 5 million years. As a consequence, Hawai'i is home to a large number of endemic species. The radiation of species described by Charles Darwin in the Galapagos Islands which was critical to the formulation of his theory of evolution is far exceeded in the more isolated Hawaiian Islands.
The Hawaiian duck or koloa is a species of bird in the family Anatidae that is endemic to the large islands of Hawaiʻi. Taxonomically, the koloa is closely allied with the mallard. It differs in that it is monochromatic and non-migratory. As with many duck species in the genus Anas, Hawaiian duck and mallards can interbreed and produce viable offspring, and the koloa has previously been considered an island subspecies of the mallard. However, all major authorities now consider this form to be a distinct species within the mallard complex. Recent analyses indicate that this is a distinct species that arose through ancient hybridization between mallard and the Laysan duck. The native Hawaiian name for this duck is koloa maoli, or simply koloa. This species is listed as endangered by the IUCN Red List of Threatened Species, and its population trend is decreasing.
Gambelia sila, commonly known as the blunt-nosed leopard lizard, is a species of lizard in the family Crotaphytidae. The species is endemic to southern California.
Hylaeus is a large and diverse cosmopolitan genus within the bee family Colletidae. This genus is also known as the yellow-faced bees or masked bees. This genus is the only truly globally distributed colletid, occurring on all continents except Antarctica.
Moʻomomi is a Nature Conservancy preserve located on the northwestern shore of Molokaʻi in Hawaii. It was established in 1988. This area is dry and hot, primarily denuded of soil due to overgrazing and poor land use practices over the last 150 years.
The Hawaiian hoary bat, also known as ʻōpeʻapeʻa, is a species of bat endemic to the islands of Hawaiʻi. Whereas the mainland hoary bat is found throughout North America, the Hawaiian hoary bat is distributed only among the major volcanic islands of Hawaiʻi, making it the only extant and native terrestrial mammal in the state; although some studies also posit that the mainland hoary bat lives in sympatry on the Hawaiian Islands alongside the Hawaiian hoary bat, this has been disputed. The Hawaiian hoary bat was officially named the state land mammal of Hawaiʻi in 2015. It is a federally listed endangered taxon of the United States.
The Mauna Loa silversword, Argyroxiphium kauense, or Kaʻū silversword, is a rare species of flowering plant in the aster family. It is endemic to the eastern and southern slopes of Mauna Loa on the island of Hawaiʻi. A. kauense occurs in mountainous shrublands, bogs, and open mesic forest. The species is managed by the National Park Service and Hawaiʻi State Department of Forestry and Wildlife. It is a federally listed endangered species of the United States. There are three known populations remaining, for a total of fewer than 1000 individuals.
Dubautia herbstobatae, the Na'ena'e or Keaau Valley dubautia, is an endangered species of shrub which is endemic to Oahu, Hawaii.
Argyroxiphium sandwicense subsp. sandwicense, the Mauna Kea silversword, is a highly endangered flowering plant endemic to the island of Hawaiʻi of Hawaii. It is the "crown jewel" of the volcanic mountain Mauna Kea, from which it derives its English name. The Hawaiian name is ʻahinahina; it applies to silverswords more broadly. The Mauna Kea silversword was once common on the volcano, and extraordinary conservation efforts are being made to preserve the species.
Hylaeus longiceps, also known as the longhead yellow-faced bee, is a species of bee endemic to Hawaii and known from only six populations. In September 2016, along with six other Hawaiian yellow-faced bee species, H. longiceps was listed for protection under the United States Endangered Species Act. This marked a first listing for any bees species in the US.
Bombus affinis, commonly known as the rusty patched bumble bee, is a species of bumblebee endemic to North America. Its historical range in North America has been throughout the east and upper Midwest of the United States, north to Ontario, Canada, where it is considered a "species at risk", east to Quebec, south to Georgia, and west to the Dakotas. Its numbers have declined in 87% of its historical habitat range. On January 10, 2017, the United States Fish and Wildlife Service placed B. affinis on the list of endangered species, making the rusty patched bumblebee the first bee to be added to the list in the continental United States.
Hylaeus anthracinus is a species of bee, also known by the common name anthricinan yellow-faced bee. It is endemic to Hawaii and known from only 16 populations. In September 2016, along with six other Hawaiian Hylaeus species, H. anthracinus was listed for protection under the United States Endangered Species Act. This marked a first listing for any bee species in the US.
Hylaeus assimulans is a species of bee, also known by the common name Assimulans yellow-faced bee. It is endemic to Hawaii and known from only five populations. In September 2016, along with six other Hawaiian Hylaeus species, H. assimulans was listed for protection under the United States Endangered Species Act. This marked a first listing for any bee species in the US.
Hylaeus hilaris is a species of bee, also known by the common name hilaris yellow-faced bee. It is endemic to Hawaii and known only from a single population. In September 2016, along with six other Hawaiian Hylaeus species, H. hilaris was listed for protection under the United States Endangered Species Act. This marked a first listing for any bee species in the US.
Hylaeus kuakea is a species of bee that is endemic to Hawaii and known from only two populations. In September 2016, H. kuakea and six other Hawaiian yellow-faced bee species were listed for protection under the United States Endangered Species Act. This marked a first listing for any bee species in the US.
Hylaeus mana is a species of bee that is endemic to Hawaii and known from only four populations. In September 2016, along with six other Hawaiian yellow-faced bee species, H. mana was listed for protection under the United States Endangered Species Act. This marked a first listing for any bee species in the US.
Hylaeus agilis is a bee species in the family Colletidae. It is endemic to New Zealand. This species is found throughout the country and visits the flowers of a wide variety of plant species, both native and introduced.
Hylaeus lunicraterius is a hymenopteran and member of the Hylaeus genus, or yellow-faced bees. This species has been solely recorded at the Craters of the Moon National Monument found in Idaho, and is endemic to this location.
Hylaeus perkinsianus, commonly known as Perkin's yellow-faced bee, is a species of yellow-faced bee in the family Colletidae. It was described by Philip Hunter Timberlake in 1926, and named for Robert Cyril Layton Perkins. The species is entirely endemic to the island of Nihoa, Hawaiian Islands, where its range covers a majority of the island. It is listed by the Center for Biological Diversity as Declining and Threatened.
