ALDABRA KESTREL Meaning and
Definition
-
The Aldabra kestrel, scientifically known as Falco araea, is a small bird of prey belonging to the falcon family, Falconidae. This endangered species is endemic to the Aldabra Atoll, a remote coral atoll located in the Indian Ocean, within the Seychelles archipelago.
The Aldabra kestrel typically measures around 23-30 centimeters in length, with a wingspan of approximately 54-68 centimeters. It displays sexual dimorphism, with males being smaller and lighter than females. The bird is characterized by a predominantly dark plumage, with its upperparts ranging from dark brown to black and its underparts off-white or pale grey in color. It possesses short and broad wings, allowing for agile flight in the open habitats it inhabits.
As a diurnal raptor, the Aldabra kestrel primarily feeds on small vertebrates such as lizards, small birds, and insects. It employs its sharp and hooked bill to capture and tear apart its prey. Nesting usually takes place in tree cavities or rocky crevices, where the female lays a clutch of 3-4 eggs. Both parents contribute to incubation and the rearing of their young.
Due to its restricted range and small population, the Aldabra kestrel faces numerous threats to its survival. Habitat loss, predation by invasive species, and climate change-induced sea-level rise are major factors contributing to its decline. Conservation efforts, including habitat protection on the Aldabra Atoll and invasive species management, are crucial for the long-term survival and recovery of this unique and vulnerable bird species.
Etymology of ALDABRA KESTREL
The word "Aldabra" in "Aldabra kestrel" refers to Aldabra Atoll, a coral atoll in the Seychelles. This is because the Aldabra kestrel (Falco araea) is native and endemic to Aldabra Atoll.
The word "kestrel" on the other hand, has its origins from Middle French "cresserelle" or Old French "creceorle", which refers to a type of falcon. It is believed to have been derived from the Old French word "crecerelle" meaning "rattle" or "ratchet", which likely refers to the sound of the kestrel's call.
