The Timor rice finch ( Lonchura fuscata , Syn .: Padda fuscata ), also called Timor rice amadine or brown rice finch , is a species from the family of the finch finches . No subspecies are distinguished. Together with the rice finch , it was assigned to the genus of rice finches . Recent molecular genetic studies have shown that this group of two species is phylogenetically located within the genus of the bronze male ( Lonchura ) and is closely related to the nutmeg bronze male there .
The population of the Timor Rice Finch was classified as “ Near Threatened ” in the IUCN's Red List of Threatened Species in 2016 , as their number has recently decreased significantly due to habitat destruction.
Appearance
The Timorese rice finch reaches a body length of 12 centimeters and weighs between 19.2 and 22.2 grams. The top of the head, the reins of the eyes, the throat and the neck are colored black. The head sides are white. The top of the body and the chest are chocolate brown and clearly set off from the cream-colored belly. The beak is blue-gray and the dark brown eyes are surrounded by a pale brown eyelid ring. Feet and legs are light flesh-colored to rosy-gray.
The Timorese rice finch shows no sexual dimorphism - males and females cannot be distinguished from one another due to their body color.
Distribution, habitat and way of life
Unlike the much more common rice finch , the Timor rice finch is only found on the island of Timor and the small islands of Semau and Roti to the west . He lives in the plains on these islands and prefers to stay in grassy areas interspersed with bushes. It can also be seen in the bushes along fields, rivers and paths. The Timorese rice finch's clutch usually comprises between four and six eggs. Both adult birds take part in the brood. The young birds hatch after about 13 to 16 days.
The Timor Rice Finch lives on grass seeds and grain . It occasionally invades the fields during harvest time. Unlike the rice finch, however, it does not form larger schools.
attitude
The first importation of the Timor rice finch can no longer be proven with certainty. For the year 1867 a Parisian dealer offered a "brown rice finch", which may have been Timor rice finches, and two such birds were also shown in 1869 at a Berlin exhibition. Their import is only proven for the year 1939 by a collector for the London Zoo . Shortly thereafter, a bird and a couple were also kept in the Berlin Zoo and the Frankfurt Zoo , respectively . Thereafter, the species seems to have been absent from European keeping for several decades. It was not until 1976 that three pairs returned to Europe and shortly afterwards the first breeding of this species was successful. In 1987 they were imported in large numbers for the first time and have been reared regularly since then, but mostly in only small numbers.
