Nyasa lovebirds
agapornis lilian
احدى انواع طيور الحب التسعة وهى ليست طفره من الفيشر او البلاك ماسك
كما يعتقد البعض
فهى نوع قائم بذاته من طيور الحب ذوات الجفون لكن نجد فى الطائر البرى لهذا اللون تقارب كبير جدا فى شكله ولونه من طائر الفيشر
وعن نفسى وبالرغم انى لم اربى هذا النوع لكن هو احب طائر الى قلبى لانى احس فيه بالنقاء والرقه مايجعل الهواة يقعون فى غرامه حتى وان حتى
م يربوه وهذا بحث مصور عن طيور اليليان ( الليليان) حاولت جاهدا ان اجمع كل الصور المتاحه وكل المعلومات عن الطائر حتى يكون مرجعا متواضعا بسيط يلجأ اليه من يريد ان يتعرف على اليليان
اولا: المورفولوجى فى اليليان ويوضح اكثر تفصيلا فى الصوره القادمه ولعلها تكون فاتحة خير باذن الله لان يسير البحث قيم وبسيط ومفهوم وليس كم فقط من الصور
هذا الطائر اصغر بقليل من طائر الفيشر وفيه منطقة الوجه بلونها يمتد حتى خلف العين بلون برتقالى احمر جميلا مقدمة الراس و والزور واعلى الرقبه حتى اعلى الصدر ( البرست) تكون orang-red
اما خلف الراس فهو اخضر مصفر ونجد ان اللون الاخضر فى تلك الطيور اكثر لمعانا
الطول للنياسا ( اليليان) لايتعدى 14 سم
وفى الحالات النقية من اليليان نجد ان الرامب والذيل لايت جرين واضح
اما العين فنجد انها تلتف من الداخل بحلقه لونها عسلى ل bare whiteويسهل تمييزها فى الطيور الكبيره والنقيه
اما الارجل فهى رمادية مزرقه
تظهر اغلب اغلب طفرات ذوات الجفون فى هذا الطائر فلايوجد اى مانع لظهورها حتى انه يمكن فيها الحصول على اليليان اللوتينو لكنه ضعيف
تنتشر هذه الطيور فى المناطق التاليه وباشكال جماعية يظهر فيها مدى الترابط فى البيئه الطبيعيه من افريقيا ( سبحان الله)
discrete, separated populations in southernmost Tanzania, Zambia–Zimbabwe border district, northwestern Moçambique, southern Malawi, and southeastern Zambia to northern Zimbabwe; also in Lundazi district, northeastern Zambia, where probably introduced, and records of aviary escapees in southern Namibia; up to 1000m; near-threatened
وهناك مجموعه من الصور الرائعه اخذت فى البريه.
وهناك مجموعة من الصور الشهيره والتى اتقطت فى الاسر
وكما تحدثت سابقا ان اغلب مانشاهده هذه الايام ليس ليليان بل انها هجنت نفسها مع الفيشر والنيجريكس والبلاك ماسك لتخرج طائر وسطيا فى شكله الظاهرى لكنه اكثر قوة وتحملا من اليليان النقى
ونلاحظ وجود بعض طفرات ذوات الجفون فى المجموعه التالية من الصور والتى قمت بوضع تصنيفها العلمى بنفسى الا بعض الصور

واخيرا احب ان اضع بعض المعلومات الاساسية والاضافيه لعل احدا يريد معلومات اكثر عن هذا الطائر
The Lilian's Lovebird (Agapornis lilianae), also known as Nyasa Lovebird, is rare and endemic to Malawi. Often mistaken for Agapornis fischeri but are smaller in size, and lack the olive-green hood and the blue lower-back of the Fischers. Nyasa species is one of the least studied of all lovebird species. There have not been any previous ecological and field studies of this species but there is a new Research Project conducted by Research Centre for Parrot Conservation (University of KwaZulu-Natal, South Africa). This study represents a very important step towards defining Nyasa Lovebird ecology and conservation.
The Nyasa Lovebird currently inhabits Liwonde National Park (LNP) and a few cluster groups occur in the surrounding forests outside LNP. Its distribution is rapidly becoming restricted to LNP because their feeding and breeding habitats are being exploited over for agricultural purposes. The extent of habitat loss outside LNP has not been determined scientifically although remaining habitat outside the LNP are fragmented Miombo Forest Reserves. Liwonde National Park is located in the southern region of Malawi, which has the highest human population density in the country approximating 100-115 inhabitants per km² (FAO, 1997). LNP is greatly impacted by population growth and agricultural activities than any other national park in the country. Recently, cases of Nyasa Lovebird poisoning have intensified although it is not known why poachers are poisoning the birds. Nyasa Lovebird Researchers assume poachers mean to poison larger mammals and Lovebirds fall victims.
Nyasa Lovebirds have proved to be a difficult species to rear in captivity. Many breeders worldwide struggle to breed the species
Normal; Nyasa Lovebird (Agapornis lilianae)
Size 135 mm
Sometimes confused with the Fischer's lovebird, the Nyasa is a slightly smaller bird with the general colouration brighter than that of the Fischer's. The facial area, extending to behind the eyes, is bright orange red with the back of the head being yellowish green. The remaining plumage is a strong green colour. When Nyasa's are of pure blood, the rump and tail show a clear light green. The bill is a bright red fading to a light horn colour close to the cere. The eye is also adorned with a white eye ring. Feet are a bluish grey.Size 135 mm
A lutino mutation exists but is genetically not a strong bird and is rarely available. In some literature a Blue mutation is said to exist
Agapornis
lilianae 14cm.
Smaller than similar A. fischeri, and with green upper tail-coverts; forehead and throat orange-red
, merging into salmon-pink on crown, face, and upper breast; bare white eye-ring; sexes alike, JUV duller with blackish suffusion on green cheeks; chattering likened to rattling of metal chain. Closely associated with mopane (Colophospermum) woodland.
DISTRIBUTION
LOCALITIES Mana Pools National Park, Zimbabwe. South Luangwa National Park, Zambia

The Nyasa lovebird is very sociable in an aviary and friendly towards birds of a similar size. In the wild, it prefers building free nests to using tree holes and crevices. The nest is typically somewhat bulky, dome-shaped, with a tubular entrance. It is constructed of stalks and bark strips exclusively by the hen, the material being carried in her beak rather than being held between her rump feathers.
In captivity, these birds prefer nest boxes, ideally 22 x 22 x 25 cm (8V2 x 8'/2 x 93/4 in) in size, with an entrance-hole diameter of 6 cm (2^4 in). Although these birds breed in colonies, and results have been achieved with multiple broods in the aviary, it's best to separate the various couples and to house them in adjoining breeding cages or small aviaries.
The Nyasa lovebird has a beautiful, lutino mutation, the physical characteristics being a red head and yellow body; it is rather small in size. The first recorded breeding of this particular mutation was in 1933, by Prendergast, in Adelaide, South Australia. It is quite possible that the mutation was unwittingly imported from the wild in the 'split' form.
The first lutinos to arrive in England were exported from Australia in 1937. It is evident that split-lutinos were in the United Statesmany years before their presence was discovered because lutinos were bred in California in 1940.
