Chidule:
Mbalame za ku Eurasian Bitterns Botaurus stellaris zomwe zimagwidwa nthawi yozizira kum'mawa kwa China nthawi yachilimwe zimachitikira ku Russia Far East. Pofuna kudziwa nthawi yosamukira, nthawi ndi njira, komanso malo oimikapo, omwe amagwiritsidwa ntchito ndi Mbalame za ku Eurasian Bitterns mumsewu wopita ku Russia Far East ndikupeza zambiri zokhudza khalidwe ndi chilengedwe kuchokera ku deta yotsatirira. Tinatsata mbalame ziwiri za ku Eurasian Bitterns zomwe zimagwidwa ku China ndi makina olembera malo padziko lonse lapansi/mafoni kwa chaka chimodzi ndi zitatu motsatana, kuti tidziwe njira zawo zosamukira ndi nthawi yawo. Tinagwiritsa ntchito mtunda womwe unasunthidwa pakati pa zosintha motsatizana kuti tidziwe momwe zimagwirira ntchito tsiku lililonse. Mbalame ziwirizi zinakhala kum'mawa kwa China m'nyengo yozizira ndipo zinayenda pafupifupi 4221 ± 603 km (mu 2015-17) ndi 3844 km (2017) mpaka chilimwe ku Russia Far East. Zotsatira za mbalame imodzi zasonyeza kuti m'zaka zonse zitatu, mbalameyi inali yotanganidwa kwambiri masana kuposa usiku, ngakhale kuti kusiyana kwakukulu kunasiyana malinga ndi nyengo, chifukwa inali yotanganidwa kwambiri usiku m'chilimwe. Chodabwitsa kwambiri kuchokera ku mbalameyi chinali kusinthasintha kwa kusamukira kwa masika komanso kusowa kwa kukhulupirika kwa malo achilimwe. Kafukufukuyu adapeza njira zosamukira za mbalame ya Eurasian Bittern ku East Asia zomwe sizinali zodziwika kale, ndipo adawonetsa kuti mitunduyi nthawi zambiri imakhala yotanganidwa kwambiri masana chaka chonse.
