The Halmahera paradise crow (Lycocorax pyrrhopterus) also known as the silky crow, is a medium sized crow like bird of paradise. One of the few monogamous birds of paradise, this paradise crow is endemic to lowland forests of Northern Maluku in Indonesia. The diet consists mainly of fruits and arthropods. It is a restricted range forest dweller from Halmahera and Morotai, in the northern Maluku of Indonesia. A common species throughout its habitat range, the Halmahera paradise crow is evaluated as being of least concern on the IUCN Red List of Threatened Species. Both sexes are similar; the female is slightly smaller than the male. The nominate subspecies has the least or no white patch on the inner flight feathers. The head is slightly glossy black brown and the upper parts are lighter than the head. The upper plumage shines slightly, with a blue gray shimmer that is most pronounced on the coat, with cinnamon brown wings. It was originally thought to be a crow (Corvidae), and was then reassigned to the birds of paradise, where it is the earliest known offshoot from the paradisaeid family tree, dating back approximately 17 million years in the Miocene period. There are two subspecies, which occur in the following regions of Maluku. Lycocorax pyrrhopterus pyrrhopterus — Halmahera, Kasiruta, and Bacan
Lycocorax pyrrhopterus morotensis — Morotai, and Rau
Previously, the Obi paradise crow (Lycocorax obiensis) was treated as a subspecies of the Halmahera paradise crow. However, due to its distinctiveness and potential for separation, it was split from L. pyrrhopterus in 2016, with the International Ornithological Congress also following through in 2021.
Halmahera paradise crow (Lycocorax pyrrhopterus) – жібекті қарға деп те аталатын, жұмақ құсына ұқсас орташа мөлшердегі құс. Бұл жұмақ құсы – жұмақ құстарының ішіндегі сирек кездесетін, моногамды түрлердің бірі. Ол Индонезияның Солтүстік Малуку аралдарындағы Халмахера және Моротай аралдарының төменгі жазықтықтағы орманды мекендейді. Оның рационы негізінен жемістер мен бунақденелілерден тұрады. Халмахера жұмақ құсы мекендеген аймақтарында кең таралған түр, және IUCN Қауіпті түрлердің қызыл тізімінде «қауіпсіз» санатында тіркелген. Екі жыныс та бір-біріне ұқсас, бірақ аналықтары еркектерге қарағанда сәл кішідірек. Номинативті подвидінің қанаттарының ішкі жағында ақ дақтар аз немесе мүлдем жоқ. Басы сәл жылтыраған қоңыр қара түсті, ал жоғарғы жағы басынан ақшыл. Жоғарғы қауырсындары көк-сұр жылтырмен сәл жарқырайды, бұл жылтыр қанаттарының қызыл қоңыр түсімен ең жақсы көрінеді. Бұл құс бастапқыда қарғалар (Corvidae) тұқымдасқа жатқызылған, бірақ кейіннен жұмақ құстары тұқымдасына қайта жіктелді. Ол жұмақ құстарының эволюциялық ағашындағы ең ерте тармақ болып саналады, шамамен 17 миллион жыл бұрын миоцен кезеңінде пайда болған. Малуку аралдарының келесі аймақтарында кездесетін екі подвиді бар:

Бұрын Obi paradise crow (Lycocorax obiensis) Халмахера жұмақ құсының (Lycocorax pyrrhopterus) подвиді ретінде қарастырылған. Алайда, оның ерекшелігі мен жеке түр ретінде даму мүмкіндігіне байланысты, 2016 жылы L. pyrrhopterus-тен бөлінді, ал 2021 жылы Халықаралық орнитологиялық конгресс де осы шешімді қабылдады.

Экология және мінез-құлық
Атаулы түрі – орманды мекендейтін, сонымен қатар бақтарда және орман шеттерінде кездеседі. Ол орманның ішкі бөлігіндегі биік ағаштарды жақсы көреді және әдетте ашық егіс жерлерінде көрінбейді. Батпақ орманда немесе мангрде сирек кездеседі, кейде кокос плантацияларында және жеміс бақшаларында кездеседі, ал өсімдіктердің ортаңғы қабатынан жоғарырақ, жапырақ шатырына дейін жиі ұшырасады. Жаннат қарғасының тамақтануы негізінен жемістерден тұрады, сонымен қатар бунақденелілерден де қосымша тамақтанады, олардың екеуі де негізінен тығыз жапырақ шатырынан және ортаңғы жапырақтардан ізделіп табылады. Көбейту маусымы шамамен желтоқсаннан маусымға дейін созылады, ал жұмыртқалар осы кезеңде туады. Еркек және ұрғашысы бір-бірінен айырмасыз болғандықтан, түр моногамды болуы мүмкін, бірақ көбейту мінез-құлқына қатысты мәліметтер жоқтың орнына. Халмахерадағы ұялар тамырлар мен мүктерден жасалған, ағаш қиыршықтарымен қапталған, үлкен шұңқыр тәрізді құрылым ретінде сипатталады, және аналық бір жұмыртқа туады.
