Malinga ndi izi, pintail ya ku Bahamian imayesedwa ngati mitundu yomwe ili pachiwopsezo chochulukirapo ndipo palibe njira zotetezera zomwe zimagwiritsidwa ntchito. Komabe, abakha m'zilumba za Galapagos amakhudzidwa ndi zinthu zomwe zimayambitsa matenda, malo awo akukhala osintha mwamphamvu, chifukwa chake kubereka kwa mbalame kumachepa. Izi zingathe kuopsezedwa ndi kuwonongeka kwa malo.
Kusunga chidutswa cha Bahamian mu ukapolo
Pofuna kusunga ma Bahamian awnks, ma aviaries a 4 mita mita ndi oyenera. Mamita pa bakha aliyense. M'nyengo yozizira, ndibwino kusamutsa mbalamezo ku gawo lina la nkhuku ndikuzisunga kutentha kosachepera +10 ° C. Amaloledwa kupita kokayenda masiku owala okha komanso nyengo yabwino. Chipindacho chimakhazikika, kapena nthambi ndi zolimba zimalimbikitsidwa. Chidebe chokhala ndi madzi chimayikidwanso, chomwe chimachotsedwa m'malo mwake chifukwa chodetsedwa.
Udzu wofewa umagwiritsidwa ntchito pogona, pomwe abakha amapuma.
Abakha a ku Bahamian amadyetsedwa njere zosiyanasiyana: tirigu, chimanga, mapira, balere. Tirigu, phala la oatmeal, chakudya cha soya, chakudya cha mpendadzuwa, udzu wouma, nsomba ndi nyama ndi chakudya cha mafupa. Onetsetsani kuti mwapereka choko kapena kabokosi kakang'ono. M'chaka, abakha amadyetsedwa ndi zitsamba zatsopano - letesi, dandelion, plantain. Mbalame zimadyera mwadyera chakudya chonyowa kuchokera ku chinangwa, grated karoti, phala.
Pakati pa nyengo yobereketsa, zakudya zopatsa thanzi zimakulitsidwa ndipo nyama ndi minced zimasakanizidwa. Zakudya zomwezo zimasungidwa panthawi ya molt. Simuyenera kudya chakudya chokhacho cha mapuloteni, motsutsana ndi chakudya chotere, matenda a uric acid diathesis amayamba ndi abakha, chifukwa chake chakudyacho chiyenera kukhala ndi mapuloteni 6-8%.
Zidutswa za Bahamian zomwe zili mu ukapolo zimagwirizana ndi anthu ena am'banja la bakha, kuti zisungidwe pamadzi amodzimodziwo.
Mnyumba ya aviary, zisa zopangira zimayikidwa pamalo abata, obisika. Abakha a ku Bahamian amabereka ndi kudyetsa ana awo pawokha. Amakhala mu ukapolo kwa zaka pafupifupi 30.
