AMAURORNIS ISABELLINA Meaning and
Definition
-
Amaurornis isabellina is a bird species commonly known as the Isabel rail. It is a medium-sized bird belonging to the family Rallidae and is found in various parts of South and Southeast Asia. The species was first described by Friedrich Boie, a German ornithologist, in 1826.
The Isabel rail has a distinctive appearance characterized by its reddish-brown plumage, which is paler on the breast and abdomen. It has a relatively short tail and a long, thin bill. The species exhibits sexual dimorphism, with males generally being larger and having brighter plumage than females.
These birds inhabit a wide range of wetland habitats such as marshes, swamps, and rice fields. They are primarily sedentary, meaning they do not migrate long distances, and are typically found near water bodies with dense vegetation. Amaurornis isabellina is primarily a herbivorous bird, feeding on a diet consisting of seeds, shoots, insects, and small aquatic invertebrates.
The breeding season for these rails varies depending on their geographical location. They construct nests on the ground, hidden among vegetation, and usually lay a clutch of 5-7 eggs. Incubation is performed by both parents, and they also jointly care for the young chicks.
The Isabel rail is considered a species of least concern on the IUCN Red List, indicating that it is not currently threatened with extinction. However, habitat loss and degradation due to human activities, as well as hunting in some areas, pose potential threats to its long-term survival.
Etymology of AMAURORNIS ISABELLINA
The word "Amaurornis isabellina" is a scientific binomial name that follows the binomial nomenclature system created by Carl Linnaeus. It consists of two parts: the genus name "Amaurornis" and the species epithet "isabellina".
The genus name "Amaurornis" is derived from the Greek words "amauros" and "ornis". "Amauros" means dark or dull, while "ornis" means bird. Therefore, "Amaurornis" can be interpreted as "dark bird" or "dull-colored bird".
The species epithet "isabellina" refers to the color isabelline, which is a pale yellowish-gray or fawn color. It is derived from the Spanish feminine name "Isabel", which means "consecrated to God" or "pledged to God".
